House of Wisdom MCP: Multi-model consultation council. Diverse AI model families investigate independently and return th
What this is — an MCP (Model Context Protocol) server that asks the same question to several different AI model families at once and hands you back every answer, unmerged.
How to read it — What it is → Quick start → The three modes → The two tools → How a call flows → Installation → Configuration. Go to Sharp edges when something surprises you.
Requires — Python 3.10+,
uv/uvx, and at least two enabled models.Reflects code as of — 2026-07-25,
master, package version0.9.3.
The medieval Bayt al-Hikma worked because it was diverse: scholars, translators, and copyists from many traditions read the same questions through different lenses, and the reader weighed the results. This server does the same with models — OpenAI, Anthropic and Google via OpenRouter, DeepSeek, local Ollama, or any OpenAI-compatible endpoint.
| It does | It does not |
|---|---|
| Fire N models in parallel on one question | Merge, rank, vote, or summarize their answers |
| Return one complete, self-contained analysis per model | Return a single "council answer" |
| Optionally let each model read your codebase first (read-only) | Ever write, execute, or network beyond each model's own endpoint |
| Tag each answer with the mode it was asked to run in | Tell you which answer is correct |
There is no synthesizer. The caller — your IDE agent — reads every perspective and decides. Treating any single perspective as ground truth defeats the design.
When it earns its cost. A call spends several model API calls and tens of seconds, so it pays off when a different model family seeing the problem would plausibly change the outcome: a contested design decision, a bug you have been circling without converging, a high-stakes or hard-to-reverse conclusion, or an explicit request for a second opinion. Work that just needs one mind's focused reasoning does not need a council.
# 1. Get a config file
curl -O https://raw.githubusercontent.com/EzzoHamdan/house-of-wisdom-mcp/master/config.example.yaml
# 2. Edit it — the only field you MUST set is `models`, and at least 2 must be enabled.
# 3. Register the server with your MCP client (see Installation for per-client syntax):
# command: uvx
# args: --from house-of-wisdom-mcp
# ai-council --config /absolute/path/to/config.yaml
# 4. Restart the client, then ask your agent to call `list_models`.
If list_models returns your roster, the server is loaded. Then try one consult
call in scribe mode — it is the fast path and needs no filesystem access.
One argument, mode, decides how much freedom each consultant gets. It is the only knob that
changes behavior at call time.
| Mode | Tools | Tool budget | Scope discipline | Use when |
|---|---|---|---|---|
scribe | none | — | — | You already pasted the relevant code into context, or the question is a judgment call needing no lookup |
translator | read-only | max_tool_iterations (built-in 8) | scope_hint is a cage — the prompt forbids wandering | You know which files matter and want each model to verify against them |
scholar | read-only | scholar_max_tool_iterations (built-in 64) | scope_hint is a starting point — the prompt permits following leads | You do not know which files matter |
With default budgets, wall-clock ordering runs scribe < translator < scholar; absolute
numbers depend entirely on which models you configured and whether they are local or remote.
Nothing enforces that ordering, though — raising max_tool_iterations above
scholar_max_tool_iterations inverts it.
Since v0.8.0 the depths between the presets are reachable per call: tool_budget lowers the
resolved mode's round budget and timeout lowers the wall-clock deadline, both clamped to the
configured values — see the consult arguments. A caller can never raise either
above what the config allows.
Precedence, highest first (synthesis.py::collect_perspectives):
| # | Source | Result |
|---|---|---|
| 1 | mode argument, if it is one of scribe / translator / scholar (case-insensitive) | that mode |
| 2 | mode argument set to anything else | logs a warning, falls through to 3 |
| 3 | legacy agentic argument | false → scribe, true → translator |
| 4 | synthesizer_tools.enabled in config | true → translator, false → scribe |
agentic is a deprecated boolean kept so older callers keep working; mode wins whenever both
are passed. scholar can only be reached by asking for it explicitly.
⚠ synthesizer_tools.enabled only picks the default in row 4. It is not a gate: an explicit
mode: "translator" or mode: "scholar" runs the tool loop even when enabled: false.
Renamed in v0.5.0.
ai_council→consultandai_council_list_models→list_models. The old names still work — they are accepted as backward-compatible aliases, so clients or scripts registered before the rename keep functioning. Only the new names are advertised, so your agent will discover and useconsult/list_modelsgoing forward.
At initialize the server sends a block of instructions (main.py::SERVER_INSTRUCTIONS) that
MCP clients surface as always-in-context text. This matters because many clients load tool
descriptions lazily — behind a search, or not at all when the tool list is long — so an
orchestrator may see nothing but the bare names consult and list_models, neither of which says
what this server is. The instructions block is the only text guaranteed to arrive, so it stands on
its own: what the server does, which tool to call, and the concrete situations worth calling it in.
Keep it short if you edit it — it costs context on every turn of every conversation.
list_modelsTakes no arguments. Returns the configured roster straight from loaded config.
{
"status": "success",
"data": {
"models": [
{"name": "GLM", "model_id": "glm-5.2:cloud", "provider": "custom", "enabled": true},
{"name": "Kimi", "model_id": "kimi-k2.7-code:cloud", "provider": "custom", "enabled": true}
],
"max_models": 3,
"enabled_count": 2
}
}
It does not contact any endpoint and does not validate API keys. enabled: true means
"present in config and not switched off", nothing more. Note that models lists every configured
entry; when a consult call names no subset, only the first max_models enabled ones fire, but
any enabled model can be requested by name — see Who actually fires.
consult| Argument | Type | Required | Meaning |
|---|---|---|---|
question | string | yes | The only required argument. Must be non-empty, max 10,000 characters. |
context | string | no | Background, max 200,000 characters. Optional since v0.7.0. In scribe mode this is the only material the models see, so paste file contents here; in translator/scholar a sentence or two is plenty, because consultants read files themselves. |
mode | string | no | scribe | translator | scholar. See resolution order. |
workspace_root | string | no | Absolute path used as the read-only sandbox root. Ignored in scribe. Must be an existing directory — a bad path fails the call with INVALID_INPUT (v0.7.1), it no longer degrades to a silent no-tools run. Falls back to synthesizer_tools.workspace_root, then to the server process's current working directory — which is set by your MCP client, not by you, and is refused when it is a home directory or filesystem root. Pass it explicitly. |
scope_hint | string | no | Free text injected into each consultant's system prompt, e.g. "Start with main.py and config.py". Ignored in scribe. |
models | array of strings | no | Subset of consultant name values to fire. Resolves against all enabled models, so any enabled model is reachable regardless of max_models or its position in the YAML. Unknown names are dropped silently; if none survive, the call fails with NO_MATCHING_MODELS. Omit to fire the default window (first max_models enabled). |
agentic | boolean | no | Deprecated alias: false → scribe, true → translator. Overridden by mode. |
tool_budget | integer ≥ 1 | no | v0.8.0. Max tool-call rounds per consultant for this call — the depth dial between the mode presets (scholar + tool_budget: 20 sits between translator's 8 and scholar's 64). Clamped to the resolved mode's configured budget, never above it. Ignored in scribe. The effective (clamped) value is reported in each perspective's tool_rounds_budget. |
timeout | integer ≥ 5 | no | v0.8.0. Wall-clock seconds for this call, applied per consultant and to the whole batch — the same double application as parallel_timeout, which it overrides downward. Clamped to the configured parallel_timeout, never above it — it makes a quick check cheap; it cannot extend a deep run. |
Success shape. One entry per model that was dispatched, in roster order:
{
"status": "success",
"data": {
"perspectives": [
{
"label": "GLM", "model_name": "GLM", "code_name": "Alpha",
"analysis": "...", "status": "ok", "mode": "translator",
"telemetry": {
"duration_s": 31.4, "tokens_in": 3000, "tokens_out": 220, "api_calls": 2,

"files_read": ["src/math.py"], "paths_listed": [], "tool_calls": {"read_file": 1}
}
},
{
"label": "Kimi", "model_name": "Kimi", "code_name": "Beta",
"analysis": "...", "status": "ok", "mode": "translator",
"telemetry": {
"duration_s": 12.0, "tokens_in": 800, "tokens_out": 60, "api_calls": 1,
"cost_usd": null, "tool_rounds_used": 0, "tool_rounds_budget": 4,
"files_read": [], "paths_listed": [], "tool_calls": {}
}
}
],
"consensus": {
"models_queried": 2, "models_succeeded": 2, "models_failed": 0,
"wall_clock_s": 31.4, "total_tokens_in": 3800, "total_tokens_out": 280,
"total_cost_usd": 0.002284
}
}
}
status: "error" and the error text sitting in
analysis. The call as a whole still reports "status": "success" as long as at least one
consultant succeeded.label equals model_name. code_name (Alpha/Beta/…) is also always present as a short handle.consensus counts nothing about agreement — despite the name, it is a dispatch tally, and
models_failed is simply the number of status: "error" entries.wall_clock_s is elapsed time, not the sum of the per-consultant durations: consultants run
in parallel, so summing them would report a number nobody actually waited.telemetry — what each perspective cost, and what it rests onAdded in v0.7.0. It is measurement, never judgment: the server still merges, ranks, and votes on nothing. It just stops you from having to take each analysis on faith.
| Field | Meaning |
|---|---|
files_read | Files this consultant actually opened, in first-touch order, deduplicated. Only successful reads — a miss or a sandbox rejection is not evidence. |
paths_listed | Directories it listed. |
tool_calls | Per-tool call counts. Measures effort, so failed calls count here even though they contribute no files_read. |
tool_rounds_used / tool_rounds_budget | Rounds spent against the budget it was given. Equal values mean it was cut off, and its answer may be partial. |
tokens_in / tokens_out / api_calls | Summed across every completion, including retry nudges and forced-final turns. Taken from the provider's own usage block; providers that omit it contribute zero. |
cost_usd | Computed from the model's configured rates. null when unpriced. |
duration_s | Wall-clock for this one consultant, reported even when it errored or timed out — a failed call still cost you something. |
finish_reason | v0.9.1. The provider's own stop reason for the completion whose text became the answer (stop, length, …). null when the provider reported none. |
truncated | v0.9.1. Derived from finish_reason: true means the answer was cut off at the output-token cap and may be incomplete. Tri-state — null means the provider never said, which is "unknown", not "no". |
Read files_read first. It is the difference between a perspective grounded in your codebase and
one that merely sounds grounded, and it changes what disagreement means:
GLM read src/auth.py → "the token refresh is racy"
Kimi read nothing → "looks fine to me"
That is not a two-way split to be weighed evenly. In scribe mode every consultant reports empty
files_read by design — the mode has no file access at all, so the field carries no signal there.
Progress notifications. If your MCP client sends a progressToken, the server emits one
notification per consultant as it finishes (3/3 consultants), so a 60-second scholar run stops
looking like a hang. Clients that don't ask for progress get none, and the council behaves
identically either way.
Error shape.
{"status": "error", "error": {"code": "...", "message": "...", "type": "...", "details": "..."}, "data": null}
code | Fires when |
|---|---|
INVALID_INPUT | question is empty, question/context is over its character cap, tool_budget/timeout is not an integer within its floor (1 / 5), or a translator/scholar call has no usable sandbox root (nonexistent path, or an implicit cwd fallback landing on a home/filesystem root) |
NO_MATCHING_MODELS | A models array was passed and matched no enabled model |
NOT_ENOUGH_MODELS_ENABLED | The fireable roster is empty (startup validation normally prevents this) |
ALL_MODELS_FAILED | Every consultant errored or the whole batch timed out |
UNKNOWN_TOOL | Tool name is neither consult nor list_models |
INTERNAL_ERROR | Unhandled exception; details carries the Python error string |
data is null on every error except ALL_MODELS_FAILED, which carries
{"attempted_models": N, "failed_responses": N}. Note that no individual analyses survive that
path — if you need partial results from a slow batch, raise parallel_timeout rather than
retrying.

| Need | Why |
|---|---|
| Python 3.10+ | requires-python = ">=3.10" |
uv / uvx | How the server is launched. Verify with uvx --version. |

Start from config.example.yaml, which is fully commented:
curl -O https://raw.githubusercontent.com/EzzoHamdan/house-of-wisdom-mcp/master/config.example.yaml
mkdir -p ~/.config/ai-council && mv config.example.yaml ~/.config/ai-council/config.yaml
~/.config/ai-council/config.yaml is the path the server checks when --config is omitted. Any
other location works if you pass --config /absolute/path.yaml.
If the path you pass to --config does not exist, the server refuses to start with
Configuration error: Config file not found: <path> (v0.7.1 — it was previously ignored
silently, booting on built-in OpenRouter defaults instead). There is still no fallback to
~/.config/ai-council/config.yaml when --config is passed; that path is only probed when the
flag is omitted entirely.
The launch command is identical everywhere; only the surrounding JSON/TOML differs.
command: uvx
args: --from house-of-wisdom-mcp
ai-council
--config /absolute/path/to/config.yaml
Why
--fromis not optional. The published package ishouse-of-wisdom-mcp; the console script it installs isai-council. Because the two names differ,uvxcannot infer the second from the first — a bareuvx house-of-wisdom-mcpfails with "An executable namedhouse-of-wisdom-mcpis not provided by packagehouse-of-wisdom-mcp". Both tokens must stay.Pinning, and tracking
master.uvxresolves to the newest release each launch. Pin with--from house-of-wisdom-mcp==0.9.3to freeze it. To run unreleased code instead, swap the package name forgit+https://github.com/EzzoHamdan/house-of-wisdom-mcp@master— every other token is unchanged.The server key is the display name. The key you give the entry under
mcpServers(House-of-Wisdombelow) is what your IDE shows as the tool prefix, e.g.House-of-Wisdom [consult]. Rename it to whatever you like — it is purely cosmetic and lives in your client config, not in this repo. Theai-counciltoken insideargsis a different thing (the installed console-script name) and must stay as-is.
Claude Desktop — Settings → Developer → Edit Config, which opens
~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or
%APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"House-of-Wisdom": {
"command": "uvx",
"args": ["--from", "house-of-wisdom-mcp",
"ai-council", "--config", "/absolute/path/to/config.yaml"]
}
}
}
Cursor — same JSON, in .cursor/mcp.json (project) or via Settings → MCP (global).
Kilo Code — same JSON, in the file opened by the MCP Servers panel
(Edit Global MCP → mcp_settings.json, or Edit Project MCP → .kilocode/mcp.json). Kilo
kills a server that is slow to answer, so raise its per-server timeout if you use scholar
mode:

"args": ["--from", "house-of-wisdom-mcp",
"ai-council", "--config", "/absolute/path/to/config.yaml"],
"timeout": 240
}
}
}
Claude Code (CLI) — the -- separator matters, otherwise claude parses --from as its own
flag:
claude mcp add House-of-Wisdom -- uvx --from house-of-wisdom-mcp \
ai-council --config /absolute/path/to/config.yaml
Codex CLI — ~/.codex/config.toml:
[mcp_servers."House-of-Wisdom"]
command = "uvx"
args = ["--from", "house-of-wisdom-mcp",
"ai-council", "--config", "/absolute/path/to/config.yaml"]
Anything else — any client that speaks stdio MCP can run this server. Only the registration syntax changes.
Config is read once at process start. Every config edit or server upgrade needs a client restart.
list_models → your roster comes back.consult with mode: "scribe", a short context, and a short question → each model
answers. This isolates model connectivity from filesystem/sandbox concerns.translator with an explicit workspace_root."Built-in" is what you get when the key is absent from your YAML. "Example file" is what
config.example.yaml ships with — these differ, so do not read the example
file as documentation of defaults.

parallel_timeout | 60 | 240 | 5–600 (seconds) |
log_level | INFO | INFO | DEBUG INFO WARNING ERROR CRITICAL |

max_concurrent_consultants | 3 | 3 | 1–32 |
openai_api_key | unset | commented out | string |
openrouter_api_key | unset | commented out | string |
synthesizer_tools.enabled | false | true | boolean |
synthesizer_tools.workspace_root | null → process cwd (refused when home / fs root) | null | absolute path to an existing directory |

synthesizer_tools.scholar_max_tool_iterations | 64 | 64 | 1–256 |
synthesizer_tools.allowed_tools | all five | all five | subset of the five tool names — ⚠ omit the key (null) for all five; [] permits none. A config pinning an explicit pre-v0.9.0 list must add content_search by name to get it |
models | 3 OpenRouter models | 6 enabled Ollama + 4 disabled paid | 2–10 entries (10 configured max, 2 enabled min) |
A minimal working config is just:
models:
- name: "GLM"
provider: "custom"
model_id: "glm-5.2:cloud"
base_url: "http://localhost:11434/v1"
api_key: "ollama"
enabled: true
- name: "Kimi"
provider: "custom"
model_id: "kimi-k2.7-code:cloud"
base_url: "http://localhost:11434/v1"
api_key: "ollama"
enabled: true
These are checked at load time. Each exits with Configuration error: … on stderr — which your
MCP client usually surfaces as "server failed to start" — wrapped in a Pydantic ValidationError,
so the strings below appear as a fragment of a longer message rather than on their own.
| Rule | Message contains |
|---|---|
At least 2 models must have enabled: true | At least two models must be enabled |
| At most 10 models configured in total | Cannot configure more than 10 models (found N) |
name values must be unique | Duplicate model names found in model configuration |
code_name values must be unique | Duplicate code names found in model configuration |
Every provider: custom entry needs a base_url | Custom endpoint '<name>' requires a base_url |
Every provider: custom entry needs an api_key | Custom endpoint '<name>' requires an api_key |
provider: openai needs a key from somewhere | OpenAI API key is required if using OpenAI models |
provider: openrouter needs a key from somewhere | OpenRouter API key is required if using OpenRouter models |
The base_url requirement is checked independently of api_key (v0.5.1). Previously validation
short-circuited on the presence of api_key, so a custom entry with a key but no base_url was
never checked and the client fell back to OpenAI's default endpoint — silently sending prompts to
api.openai.com. A base_url-less custom entry is now rejected at startup (and guarded again at
client construction).
| Field | Required | Notes |
|---|---|---|
name | yes | Human label. This is the string the models call argument matches against. |
model_id | yes | Provider's identifier: an Ollama tag, an OpenRouter slug, an OpenAI model name. |
provider | no (default openrouter) | openai | openrouter | custom |
base_url | for custom | OpenAI-compatible /v1 endpoint. Not enforced when api_key is set — see the warning above. |
api_key | for custom, else optional | Overrides the provider-level key for this entry. |
enabled | no (default true) | false keeps the entry configured but dormant. |
code_name | no | Auto-assigned from Alpha, Beta, Gamma, … if omitted. A short stable handle, always returned in the payload alongside model_name. ⚠ Setting it by hand on some entries while running close to the 10-model cap can crash startup — see Sharp edges. |
input_cost_per_1m | no | USD per 1M input tokens. Purely for reporting: turns the provider's own token counts into telemetry.cost_usd. |
output_cost_per_1m | no | USD per 1M output tokens. Same. |
Leave both pricing fields unset for local or free endpoints. cost_usd is then reported as null
rather than 0.0 — "not priced" and "measured as free" are different claims, and only one of them
is true for an unpriced cloud model.
Local Ollama — free, api_key can be any non-empty string:
models:
- name: "GLM"
provider: "custom"
model_id: "glm-5.2:cloud" # a tag from `ollama list`
base_url: "http://localhost:11434/v1"
api_key: "ollama"
enabled: true
OpenAI — one shared key at the top of the file:
openai_api_key: "sk-..."
models:
- name: "GPT-5.6-Terra"
provider: "openai"
model_id: "gpt-5.6-terra"
enabled: true
Claude / Gemini / most others via OpenRouter — one key, many families. model_id is the slug
from openrouter.ai/models:
openrouter_api_key: "sk-or-..."
models:
- name: "Claude Opus"
provider: "openrouter"
model_id: "anthropic/claude-opus-4"
enabled: true
- name: "Gemini Pro"
provider: "openrouter"
model_id: "google/gemini-2.5-pro"
enabled: true
DeepSeek direct, Perplexity, Groq, Together, vLLM, LM Studio — anything OpenAI-compatible uses
provider: custom with its own base_url and api_key. Use a ${ENV_VAR} placeholder to keep
the secret out of the file (see Keeping keys out of the YAML):
models:
- name: "DeepSeek-Pro"
provider: "custom"
model_id: "deepseek-chat"
base_url: "https://api.deepseek.com/v1"
api_key: "${DEEPSEEK_API_KEY}" # resolved from the environment at load time
enabled: true
Per model, first match wins:
api_key on the model entry — always wins for that entry, whatever the provider.openai_api_key for provider: openai, openrouter_api_key for
provider: openrouter), which is itself resolved as CLI flag → YAML top-level field →
environment variable.provider: custom entries never fall back to a provider-level key; they require their own
api_key.
The environment variable names are AI_COUNCIL_OPENAI_API_KEY and
AI_COUNCIL_OPENROUTER_API_KEY (v0.5.1 — the fields no longer declare a Pydantic alias, so the
AI_COUNCIL_ prefix applies to them like every other setting). A bare, unprefixed
OPENAI_API_KEY / OPENROUTER_API_KEY in the environment your MCP client launches is not
picked up — set the prefixed name, or pass the key via YAML or the CLI flags.
All settings use the prefix and match case-insensitively:
AI_COUNCIL_OPENAI_API_KEY, AI_COUNCIL_OPENROUTER_API_KEY, AI_COUNCIL_MAX_MODELS,
AI_COUNCIL_PARALLEL_TIMEOUT, AI_COUNCIL_LOG_LEVEL, AI_COUNCIL_LOG_FORMAT,
AI_COUNCIL_MAX_CONCURRENT_CONSULTANTS.
The config file describes structure (which models, timeouts, modes); secrets belong in the
environment. Keeping config.yaml secret-free means you can hand it to an AI agent to edit, or
even commit it, without leaking a key. Three ways to supply keys without touching the file:
Environment variables — set the AI_COUNCIL_-prefixed names. For MCP the cleanest place is
your client's env block, so the server inherits them at launch:
"env": {
"AI_COUNCIL_OPENAI_API_KEY": "sk-...",
"AI_COUNCIL_OPENROUTER_API_KEY": "sk-or-..."
}
A .env file — the server reads one next to the config file and one in the working
directory, before it parses any keys. Copy the committed .env.example to .env
(it's gitignored) and fill it in; use the same AI_COUNCIL_-prefixed names:
AI_COUNCIL_OPENAI_API_KEY=sk-...
AI_COUNCIL_OPENROUTER_API_KEY=sk-or-...
A real environment variable (e.g. from the client env block) always wins over the .env file.
${ENV_VAR} placeholders — any api_key or base_url value may reference an env var, which
is expanded at load time. This is the only secret-free path for a per-model api_key on a
provider: custom entry (DeepSeek, Groq, …), since those never fall back to a provider-level key:
api_key: "${DEEPSEEK_API_KEY}"
A referenced-but-unset variable fails loudly at startup, naming the missing var — it is never silently sent as an empty key.
config.yaml, *.local.yaml, and .env are gitignored, so a filled-in config can't be committed
by accident.
The per-call roster is built one of two ways, then bounded by concurrency:
configured models ── enabled: true ──► enabled models
│
no `models` arg ◄─────┴─────► `models` arg passed
│ │
[:max_models] match names against ALL enabled models
│ │
default window this call's roster (any enabled model, any position)
└──────────────┬───────────────┘
▼
this call's roster ── semaphore ──► N running at once (all modes)
max_models (1–10) caps the default fan-out — the roster used when a call names no subset.
The window is the first max_models enabled entries by position in the YAML list, not by
preference.models argument resolves against the full enabled list, so any enabled model
is reachable by name regardless of max_models or its position. With eight enabled models and
max_models: 3, asking for the seventh by name fires exactly that model. A named subset is not
re-capped to max_models — the caller chose the models, and max_concurrent_consultants still
bounds how many run at once.max_concurrent_consultants (1–32) caps how many consultants run simultaneously; the rest queue.
Match it to your provider's concurrency allowance (Ollama Cloud Pro = 3, Max = 10). It applies in
all modes — scribe included, since v0.6.2 — so a large roster no longer fires every model
at once.In translator and scholar modes each consultant gets its own read-only tool loop, rooted at
workspace_root. These tools are internal to the consultant; they are never exposed to your MCP
client.
| Tool | Signature | Behavior |
|---|---|---|
read_file | path | UTF-8 read, truncated at 200,000 bytes with a ...[truncated] marker. Undecodable bytes are replaced, not fatal. |
list_dir | path (default root) | One entry per line, relative to root, / suffix on directories. |
glob_search | pattern | Glob relative to root, e.g. **/*.py. Capped at 100 results. |
content_search | pattern, glob? | v0.9.0. Regex grep over file contents; returns path:line: text hits. Bounded on every axis: 100 matches, 2,000 files scanned, 200,000 bytes read per file, 300 chars per shown line. Binary files and dot-directories (.git, caches) are skipped — dot-files stay searchable. Every candidate is re-checked against the sandbox boundary, so a symlink cannot leak outside content. |
think | thought | Echoes the thought back. No I/O. Costs budget on the same terms as the others. |
Restrict the set with synthesizer_tools.allowed_tools; a call to a tool outside the list returns
an error string to the model rather than executing. ⚠ Distinguish the two "empty" cases: omitting
the key (null) permits all five, while allowed_tools: [] permits none — an empty allowlist
advertises no tools, so every consultant loses read access. To narrow the surface, name the tools
you want, e.g. ["read_file", "think"]; to grant everything, leave the key out.
tools.py::ToolRegistry.call).workspace_root. Paths are resolved with Path.resolve() and checked with
relative_to(), so symlinks pointing out of the root are rejected as SandboxViolation
(tools.py::ToolRegistry._resolve).scribe mode.list_models.The loop stops when the model replies with plain text instead of tool calls, or when the budget is spent — after which it gets one forced turn to answer from what it gathered, and a second nudge if that comes back empty.
The budget counts rounds, not individual tool calls: one unit per assistant turn that contains
tool calls, however many it contains. A model that requests four files in a single turn spends one
unit, not four — and a think batched alongside them is free. As of v0.6.3 the system prompt says
this plainly ("you have at most N rounds; a round is one turn, batched calls cost one round"), so
the prompt matches the accounting. A batching model can therefore legitimately read more of your
workspace per round than a naive per-call reading of the number would suggest — the frugality
guidance ("read only what matters, do not read speculatively") is what keeps reads bounded.
Values are hardcoded in models.py; listed here because they are not otherwise visible from the
outside.
| Path | Temperature | max_tokens | Timeout |
|---|---|---|---|
scribe (call_model) | 0.7 | 8,000 | parallel_timeout, applied to the whole batch |
translator / scholar (call_model_with_tools) | 0.4 | 16,000 | parallel_timeout, applied both per consultant and to the whole batch |
A per-call timeout argument (v0.8.0) substitutes for parallel_timeout in both rows — same
double application — but only downward: it is clamped to the configured value.
Empty responses get one automatic retry. Models that return their answer in a reasoning,
thinking, or reasoning_content field instead of content — common with Ollama's cloud
thinking models — are handled by models.py::_extract_text.
Per-provider request adaptation (v0.5.2, models.py::_create_completion): for provider: openai
the output cap is sent as max_completion_tokens instead of max_tokens (newer OpenAI models
reject the latter). If a model still rejects a parameter — e.g. reasoning models accept only the
default temperature: 1 — that parameter is dropped and the call retried (up to three strips).
custom / openrouter endpoints are sent the classic max_tokens / temperature unchanged.
One rejection needs the opposite adaptation (v0.9.1): OpenAI reasoning models refuse function
tools on /v1/chat/completions unless reasoning_effort is 'none' — a parameter the server
never sends, so there is nothing to strip. That specific 400 is retried once with
reasoning_effort: "none", and the model is remembered so a tool loop pays the discovery request
once, not once per round. The trade is explicit: on such models, translator/scholar run
without extended reasoning rather than not at all; scribe (no tools) is unaffected.
⚠ Because parallel_timeout also bounds the whole batch, and because queued consultants spend
their wait inside that window, a scholar run with more models than
max_concurrent_consultants needs a generous value. When the batch timeout fires, only the
consultants still running are cancelled and marked as timed out; perspectives that already
finished are kept (v0.5.1), so a slow straggler no longer collapses a partial success into
ALL_MODELS_FAILED.
Known divergences between what the system looks like it does and what it does. Each is verified in code.

Fixed in v0.9.1 — reasoning models with tools, and visible truncation. OpenAI reasoning models rejected every tool-bearing call (
translator/scholardied on round one) because chat completions requiresreasoning_effort: 'none'for function tools — now detected and adapted automatically, at the documented cost of running those modes without extended reasoning. And telemetry gainedfinish_reason/truncated, closing the gap where an answer cut off at the token cap was indistinguishable from a complete one.models.py,main.py.
Added in v0.9.0 — content search, CI, and packaging. A fifth sandbox tool,
content_search, greps file contents by regex (path:line: texthits, bounded at 100 matches / 2,000 files / 200 KB per file, binary and dot-directories skipped, sandbox boundary re-checked per candidate). Locating a symbol previously meant globbing names and reading whole files — spending the round budget on enumeration. It is in the defaultallowed_tools; configs pinning an explicit older list must add it by name. Separately: GitHub Actions now runs the full test suite and ruff on every push/PR (Python 3.10–3.13), and a release-triggered workflow publishes to PyPI via trusted publishing.tools.py,config.py,models.py,.github/workflows/.
Added in v0.8.0 — per-call depth dials.
consultgained optionaltool_budget(max tool rounds per consultant) andtimeout(wall-clock seconds) arguments. Both are clamped to the operator's configured ceilings — the resolved mode's round budget andparallel_timeoutrespectively — so a caller can dial a call down (a 20-round scholar, a 30-second sanity check) but never past what the config allows. Invalid values fail asINVALID_INPUT; the effective budget is visible in each perspective'stool_rounds_budget.main.py,synthesis.py,models.py.
Fixed in v0.7.1 — the lying edges. Two long-documented sharp edges were resolved. (1) A
translator/scholarcall now validates its sandbox root before any consultant fires: a nonexistentworkspace_rootfails the call withINVALID_INPUTinstead of silently degrading to a no-tools run still tagged with the requested mode — and if the fallback path ever does fire (unexpected setup failure), the perspectives are stamped with the mode that actually ran (scribe). The implicit cwd fallback is refused when it lands on a home directory or filesystem root; passing such a path explicitly still works. (2) A typo'd--configpath is now a startup error instead of a silent boot on built-in OpenRouter defaults.synthesis.py,main.py,config.py.
Added in v0.7.0 — telemetry and progress. Every perspective now carries a
telemetryblock: which files that consultant actually read, how many tool rounds it spent against its budget, its token counts and wall-clock, andcost_usdwhen the model hasinput_cost_per_1m/output_cost_per_1mconfigured (unpriced models reportnull, never0.0).consensusgainedwall_clock_sand batch token/cost totals. None of this merges or ranks anything — it is the evidence behind each answer, andfiles_readin particular distinguishes a grounded analysis from a confident one. Separately, the server now emits an MCP progress notification per consultant when the client sends aprogressToken.main.py,models.py,synthesis.py,tools.py,config.py.
Changed in v0.7.0 — discoverability. The server was functionally correct long before it was reachable: models rarely called it. Six causes were fixed. (1) The server now sends
instructionsatinitialize, so a client that lazily loads tool schemas still knows what this server is — previously it sent none, and an orchestrator could see only the bare tool names. (2) Theconsultdescription no longer opens by redirecting the caller to a different, possibly uninstalled MCP server. (3) It now leads with concrete situations worth calling it in, instead of leading with latency figures and "do NOT fire reflexively". (4) Theagenticmigration trivia moved out of the description into the field schema where it belongs — the blurb went from ~2,300 to ~1,250 characters. (5)contextis now optional; onlyquestionis required, so the cheapest valid call is one argument. A blankcontextemits no header into the consultant prompt. (6) The README's own "do not fire on every prompt" framing was rewritten to say when the tool earns its cost. No behavioral change to dispatch, modes, or the sandbox.
Changed in v0.6.3.
anonymous_perspectiveswas removed — it only rewrote the displaylabelwhile the realmodel_namestayed in the payload, so it hid nothing from an AI orchestrator (which reads every field). Model identity is intentional signal the caller may weigh;code_nameremains as a short handle. An old config that still sets the key is silently ignored. Also: the consultant tool-budget prompt now states its accounting honestly (N rounds, batched calls cost one round), alog_format: text | jsonoption (and--log-format) adds line-delimited JSON logs, and duplicate modelnamevalues are rejected at startup.
Fixed in v0.6.2. A full-source audit resolved a batch of defects:
glob_searchno longer escapes the sandbox via..patterns; SCHOLAR mode's prompt no longer contradicts itself (mode guidance sits outside the strict scope cage); the budget-exhaustion forced-final turn answers its pendingtool_callsso strict endpoints no longer 400;allowed_tools: []sends an omittedtoolsparam instead oftools: [];read_file's truncation marker is byte-accurate and its cap is no longer overridable; the.envparser strips inline comments. Plus two reliability changes: transient API failures (429 / 5xx / connection) now retry with bounded backoff, and themax_concurrent_consultantssemaphore applies inscribemode too (it previously fired every model at once).models.py,tools.py,synthesis.py,config.py.
Fixed in v0.6.1. The per-call
modelsargument now resolves against the full enabled list, so an explicitly named enabled model is reachable regardless ofmax_modelsor its position in the YAML.max_modelsagain caps only the default (no-subset) fan-out, and theNO_MATCHING_MODELSdetail reports the true full enabled set.config.py::get_enabled_models,main.py::_process_ai_council.
Fixed in v0.5.1. Nine long-standing sharp edges were resolved: the
AI_COUNCIL_env prefix now works (and a bareOPENAI_API_KEYis no longer silently adopted); a batch timeout keeps consultants that already finished;statusis carried explicitly instead of guessed from the text; acustommodel withoutbase_urlis rejected instead of talking toapi.openai.com;allowed_tools: []now permits nothing;code_nameauto-assignment no longer skips names or crashes at 10 models; the advertised version tracks the package;synthesis_model_selection(dead) was removed; and theconsultdescription no longer quotes example-config defaults.

Run the tests with uv run pytest (or pytest -q inside an activated venv). 170 tests cover
config parsing, sandbox path resolution, the tool loop, mode resolution, workspace-root
validation, per-call override clamping, content search, prompt assembly, transient retry,
telemetry, progress notifications, and the discoverability contract. All model I/O is stubbed —
no test hits a live endpoint. CI (.github/workflows/test.yml) runs the suite plus ruff check
on every push and PR across Python 3.10–3.13; .github/workflows/publish.yml builds and uploads
to PyPI on a GitHub release via trusted publishing.
Inspired by Cognition Wheel, which established the wisdom-of-crowds approach to multi-model consultation. This project diverges from it in dropping the synthesis step entirely, adding the three named modes, giving every consultant its own read-only investigation loop, and pushing the weighing of perspectives back onto the caller. The medieval House of Wisdom supplied the name and the principle: many lenses, weighed by the reader, not merged by an authority.
