mcp: Instructions file for Codex

AGENTS.md

mcp AGENTS.md is an instructions file for Codex, OpenCode from Teamwork/mcp. It costs 24,231 tokens per session, scanned A, original, MIT.

Repository instructions for AI coding agents working on a public MCP project. They describe the project, setup and run commands, and what information may be included in public changes.

In plain words
What is it for?
Use them when changing, testing, documenting or reviewing this repository, especially before committing publicly visible work.
Why use it?
They reduce mistakes by making project rules and public-information limits explicit. This helps agents avoid exposing private services or internal implementation details in code and documentation.

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

This is Teamwork/mcp's own configuration. It tells Codex and OpenCode how to work on 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 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

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 yesterday.

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 — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

A concise guide for AI coding agents working on this repository. It complements README.md with machine-actionable build, test, run, and convention notes.

This repository is public

Everything committed here is world-readable and permanent — source, comments, tests, docs, commit messages, PR titles and descriptions, issue text. A later fix does not retract what has already been cloned, cached or indexed. This file is public too, and is bound by its own rules.

Using an internal source to get the behaviour right is fine; publishing it is not. Only the externally observable result belongs in the repo.

  • Never name private repositories or services. desksdkgo, twapi-go-sdk and the MCP SDK are public and may be cited freely. The backends behind the Projects and Desk APIs are not — do not name their repositories, packages, files, handlers, models, or query-argument identifiers. Describe the HTTP endpoint instead: route, parameters, JSON keys, status codes.
  • Never name internal infrastructure. Deployments, hostnames, dashboards, monitoring, CI tooling, chat channels, wikis, runbooks, or environment detail beyond the documented TW_MCP_ENV values.
  • Never reference internal tracking. Ticket keys, incident IDs, or links and commit hashes in private repositories. Public protocol references (SEP-2575) are fine — those are published.
  • Never describe a backend defect as a defect. State what the endpoint does today ("list endpoints clamp pageSize over 100 to 100"), not that it is a bug, what causes it, or when it is due to be fixed — the service is still running the old code.
  • Never publish unreleased information. Roadmap items, planned deprecations, dated fixes, feature flags, or capacity and traffic figures.
  • Never commit real data. Tokens, API keys, cookies, real installation subdomains, or real customer and employee names, emails and IDs — in code, tests, fixtures, log samples and error strings alike. Fixtures use example.com, test.teamwork.com, [email protected], and IDs like 777/12345.

Changes

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.
