agent-passport-mcp: Instructions file for Codex

AGENTS.md

agent-passport-mcp AGENTS.md is an instructions file for Codex, OpenCode from aeoess/agent-passport-mcp. It costs 759 tokens per session, scanned A, original, Apache-2.0.

Project instructions for AI coding agents working on a Model Context Protocol server. The server exposes software tools for issuing and checking digital passports, delegations, receipts, and governance decisions.

In plain words
What is it for?
Use it when adding or changing MCP tools, running tests and builds, checking the tool count, or preparing a pull request.
Why use it?
It gives agents the project background, required setup, testing steps, and contribution rules in one place. This helps prevent changes that break compatibility with the related SDK.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is aeoess/agent-passport-mcp's own configuration. It tells Codex and OpenCode how to work on agent-passport-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-passport-mcp configures →

Token cost

What it costs to keep this loaded

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.

Security

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 7d 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.

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 install installs both this package and the SDK dep.
  • src/index.ts is the single-file source of all MCP tool registrations. Do not split until there is a real reason.

Test before you ship

  • npm test full suite must exit 0.
  • npm run build produces dist/, checked via the postinstall hook.
  • npm run inspector launches 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 McpError with ErrorCode.InvalidParams or ErrorCode.InternalError, never throw raw Error to the MCP transport.
  • No console.log. Use process.stderr with structured prefixes if debug output is absolutely required.

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.
