Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00857 | $0.00857 |
| Opus 5.5 | $0.00343 | $0.00343 |
| Sonnet 5.5 | $0.00171 | $0.00171 |
| Haiku 4.5 | $0.00086 | $0.00086 |
Grade A, and why
agent-passport-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Context and instructions for AI coding agents working on agent-passport-system-mcp.
About this project
agent-passport-system-mcp is the Model Context Protocol server that exposes APS protocol primitives as MCP tools. Every public SDK primitive has a corresponding MCP tool registered via server.tool(...). LLM-facing agents call these tools to issue passports, build delegations, verify receipts, evaluate governance, etc. Apache-2.0.
This repo is tightly coupled to agent-passport-system (the SDK). Version alignment matters: when the SDK adds a primitive, this repo adds the corresponding tool. The tool count is part of the public narrative.
Dev environment
- Node.js >= 20
npm installinstalls both this package and the SDK dep.src/index.tsis the single-file source of all MCP tool registrations. Do not split until there is a real reason.
Test before you ship
npm testfull suite must exit 0.npm run buildproducesdist/, checked via the postinstall hook.npm run inspectorlaunches the MCP Inspector for manual tool-call testing. Use this when adding new tools.- Count tools with
grep -c 'server.tool(' src/index.ts. The count must match the version bump reason.
PR instructions
- Title format:
<type>(<scope>): <summary>per Conventional Commits. - Never merge your own PR. Never push to
main. - Version bumps are a human decision. Open a PR proposing the bump.
- If the SDK bumps major, this repo bumps major. Keep the coupling explicit in the PR description.
- New tools require a test, a JSDoc block on the handler, and a Zod schema for input validation.
Code style
- Strict TypeScript.
- Zod for every tool input schema. No manual JSON validation.
- Error responses use
McpErrorwithErrorCode.InvalidParamsorErrorCode.InternalError, never throw rawErrorto the MCP transport. - No
console.log. Useprocess.stderrwith structured prefixes if debug output is absolutely required.
What this repo is and is not
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agent-passport-mcp AGENTS.md is an instructions file published in the GitHub repository aeoess/agent-passport-mcp (4 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 857 tokens to every session, about $0.0034 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
