Proofpane

Proofpane is an AI governance platform — the evidence plane for governed AI work. Every AI action across coding agents (Claude Code, Cursor, Codex, Hermes, Claude Desktop), workflow platforms (n8n, UiPath, Power Automate, Zapier, Make) and direct LLM API calls is policy-gated in the execution path (allow / deny / redact / pause for a human), cost-metered, and recorded in a SHA-256 hash-chained, tamper-evident audit log that exports as an Ed25519-signed Evidence Pack an auditor verifies offline — no vendor account, no trust in us required.

The architecture

Our claim: governance must happen at runtime, and the record it leaves must be tamper-evident. A policy that is checked after the fact governs nothing — by the time a review reads the log, the secret has left, the payment has cleared, the decision has shipped. So the gate sits in the execution path: the AI action does not complete until policy has allowed it, redacted it, or paused it for a human. And a record the operator can quietly edit proves nothing — so every decision is appended to a SHA-256 hash-chained, append-only log (DB-level immutability trigger, Ed25519 chain-head anchoring) whose export any auditor can verify offline, against a published rubric, without trusting the operator or us. Runtime enforcement produces the evidence; the evidence does not depend on anyone's word — including ours.

The architecture is a public, versioned reference — not a private rubric:

• Read it: proofpane.com/architecture — interactive map + full Markdown spec
• Cite it: DOI 10.5281/zenodo.21402331 (CC BY 4.0 — anyone may implement it)
• Core claim: evidence must be checkable by parties who trust neither the operator nor the vendor — and so must the rubric it is graded against. A standard that can quietly move is not a standard.

The MCP server below is one enforcement point of this architecture: the on-machine gate for MCP-speaking AI clients.

This repo

This repo hosts download artefacts for proofpane.com and is the public home of the Proofpane MCP server (the airgov_daemon). The main Proofpane codebase is private; this public mirror gives browsers (Chrome Safe Browsing, Edge SmartScreen) a high-reputation host so downloads aren't flagged as "unverified".

What you can do with just the download

No account, no pairing, no talking to us first:

• Run the MCP server — airgov_daemon mcp serves 13 governed tools (bash, read, write, edit, glob, grep, listdir, RAG search, session search, skills) to any MCP client. Local policy gates and DLP redaction are active: a secret in a file read is masked before the model sees it, on your machine, with no cloud in the loop.
• Scan your coverage — airgov_daemon coverage reads this machine's AI-client configs and shows which MCP servers route through governance and which run direct (ungoverned).
• Check the monitoring switch — airgov_daemon monitoring-status, and disable / enable <app> to turn per-app monitoring off and on.
• Preview usage extraction — airgov_daemon usage-sync --dry-run shows what token/usage data WOULD sync, without sending anything.

Pairing with a Proofpane org (airgov_daemon pair <CODE>) connects the daemon to the server side: the cloud audit chain, human-approval gates, org-wide policy sync, and Evidence Pack export.

Proofpane MCP server

airgov_daemon mcp is a stdio Model Context Protocol server — a governance layer that runs on the user's machine and exposes local tools to MCP clients (Claude Desktop, Cursor, Codex, …) under policy control. Every call is policy-gated, DLP-redacted before a model sees a secret, and recorded on a hash-chained, offline-verifiable audit trail.

Tools advertised (tools/list, no pairing needed): bash, read, write, edit, glob, grep, listdir, search_compliance_docs, ingest_to_rag, session_search, skills_list, skill_view, skill_manage.

Run it

airgov_daemon mcp     # stdio MCP server (from a downloaded binary)

Container / directory checks (e.g. Glama)

A Dockerfile is included that pulls the public prebuilt Linux binary and runs the server in mcp mode, so an automated directory can start it and introspect (initialize + tools/list) without the private source:

docker build -t proofpane-mcp .
docker run --rm -i proofpane-mcp     # speaks stdio MCP

Get the daemon

See proofpane.com/install for the guided install. Direct download links live on the Releases page.

SHA-256 verification

Every binary ships with a .sha256 sibling:

shasum -a 256 -c ProofpaneDaemon-macos-x86_64.zip.sha256
