aso-mcp — the free Agent Readiness Scanner

What's your ASO score?

SEO made you visible to search engines. ASO (Agent Signal Optimization) makes you discoverable, trustable, and payable by the AI agents that are becoming the web's next visitors.

aso-mcp is the free, open-source ASO Scanner — an MCP server that scans any website and produces an Agent Readiness Report scored on the open ASO framework. The beta npm package is @forgemeshlabs/aso-audit-mcp.

Beta. Experimental ASO scanner for evaluating whether agents can discover, trust, understand, and use a website/API/tool. ASO scoring is experimental and will evolve as agent standards mature.

=== Agent Readiness Report: https://example.com ===
ASO Score: 70/100
Agent Readiness: Ready
Level: ASO-4 Trustable — Agents can verify trust, reputation, and operational signals.

Discoverability  20/20    Identity  15/20    Trust   11/15
Commerce          5/15    Reputation 4/15    Memory  15/15

What it checks — 33 signals across 6 pillars

Find gaps in discovery, trust, interoperability, and commerce — every emerging agent standard in one scan:

Every check returns pass / partial / fail with concrete evidence and a fix recommendation. Results roll up into the six ASO pillars (Discoverability 20, Identity 20, Trust 15, Commerce 15, Reputation 15, Memory 15) → your ASO Score and maturity level.

Install

Requires Node.js ≥ 18. Published on npm as @forgemeshlabs/aso-audit-mcp — no clone or build needed.

npm install -g @forgemeshlabs/aso-audit-mcp

Or skip the install entirely and run it with npx (recommended for MCP clients):

npx -y @forgemeshlabs/aso-audit-mcp

Claude Code

claude mcp add aso -- npx -y @forgemeshlabs/aso-audit-mcp

Claude Desktop / Cursor / Windsurf (any MCP client)

{
  "mcpServers": {
    "aso": {
      "command": "npx",
      "args": ["-y", "@forgemeshlabs/aso-audit-mcp"]
    }
  }
}

Development (from source)

Only needed if you're hacking on the scanner itself:

git clone https://github.com/forgemeshlabs/aso-audit-mcp
cd aso-audit-mcp
npm install && npm run build
claude mcp add aso -- node /path/to/aso-audit-mcp/dist/index.js

Tools

Try it: "Scan example.com for agent readiness" · "What's my ASO score?" · "Give me a fix plan to make my site agent-ready."

CLI smoke test (from a source checkout)

npm run smoke -- https://your-site.com

Glama / registry metadata

This repository includes glama.json for Glama MCP registry ownership and install metadata.

• Package: @forgemeshlabs/aso-audit-mcp
• Current release: v0.1.3
• Transport: local stdio
• Authentication: none required for local stdio use. The scanner does not ask for API keys, tokens, cookies, or third-party credentials.
• HTTP deployment: not enabled by this npm package. Any public HTTP deployment of this scanner must add authentication, per-client rate limits, request logging, and an egress policy before exposure.

Recommended Glama/MCP install command:

npx -y @forgemeshlabs/aso-audit-mcp

Example usage after connecting the server to an MCP client:

Scan https://example.com for agent readiness.
Give me the ASO fix plan for example.com.
Check only the llms-txt signal for example.com.
List the ASO scanner checks.

Release verification:

• Git tag: v0.1.3
• npm package: @forgemeshlabs/aso-audit-mcp
• MCP server version: 0.1.3

v0.1.3 is the Glama-ready release: the tagged source includes glama.json, npm installation metadata, usage examples, release verification, and local stdio authentication notes.

Glama release build

Glama installability requires a Glama release, which is a containerized build created from the Glama Dockerfile admin page, not a GitHub release. This repo includes a production Dockerfile and GLAMA.md with the build spec values to use in Glama:

Build steps:

npm ci
npm run build
npm prune --omit=dev

Runtime command:

node dist/index.js

In Glama's CMD arguments field, enter:

["node", "dist/index.js"]

Do not leave CMD arguments as []; Glama validates that field separately from the Dockerfile CMD.

The ASO framework

SEO ranks pages for people. ASO prepares services for agent selection, invocation, payment, and repeat use.

Scores from this scanner are directional self-assessments. ASO Certification (ASO-3+) requires verified evidence — see the scoring rubric and agentsignaloptimization.com for audits, certification, and the full framework.

Security

This scanner makes outbound requests to URLs you give it, so it is built to resist SSRF abuse:

• Scheme allow-list — only http/https; file:, ftp:, gopher:, data: etc. are rejected.
• Private-target blocking — after DNS resolution, requests to loopback, private (RFC 1918), link-local, CGNAT, reserved, multicast, and the cloud metadata address (169.254.169.254) are refused. IPv6 loopback/ULA/link-local and IPv4-mapped forms are covered too. If a hostname resolves to any private address, the scan is refused.
• Pinned-IP transport — each request dials the exact public IP that was validated, while TLS still verifies the original hostname. This closes the validate-then-connect DNS rebinding window.
• Manual redirect validation — automatic redirect following is disabled; every hop is re-validated against the same rules, capped at 5 redirects. A public URL that 30x-redirects to an internal address cannot slip through.
• Untrusted remote content — parsed manifests are omitted from tool output by default (include_artifacts: true to opt in, and they are then explicitly labeled untrusted); embedded text excerpts are control-char-sanitized and length-capped. Treat any returned remote content as data, never instructions.
• Bounded — GET only, ASO-Scanner/1.0 UA, max 6 concurrent, 10s timeout, 512KB body cap. Never authenticates, never POSTs, never crawls beyond well-known paths.
• Tested hardening — npm test covers unsafe URL rejection, private IP ranges, artifact sanitization, redirect blocking, redirect hop caps, and the test-only loopback escape hatch.

Deployment: stdio (local, per-user) is the safe default. A public HTTP deployment is a network-egress tool and must add authentication, per-client rate limiting, request logging, and an egress policy before exposure.

• Reputation signals (citations, reviews, success rates) cannot be auto-verified by a crawler; they are reported as manual and scored 0 until verified by audit — so the auto-verifiable maximum is 89/100. That is intentional honesty, not a bug.
• Emerging specs (MCP Server Cards SEP-1649/SEP-2127, DNS-AID, Web Bot Auth, UCP/ACP/MPP) move fast. PRs updating paths welcome.
