mcp: Instructions file for Codex

AGENTS.md

mcp AGENTS.md is an instructions file for Codex, OpenCode from temporal-cortex/mcp. It costs 538 tokens per session, scanned A, original, MIT.

A set of project instructions for the Temporal Cortex MCP documentation repository. MCP is a standard way for AI tools to connect to external services and tools.

In plain words
What is it for?
Use it when updating the repository, checking links, keeping version details consistent, or adding setup and integration examples.
Why use it?
It gives coding agents the project structure, build and test checks, coding conventions, and rules for adding examples. This reduces guesswork when changing the documentation.

Instructions file for CodexOpenCode

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

This is temporal-cortex/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 2mo 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.

The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Temporal Cortex MCP

Public documentation repo for the Temporal Cortex MCP server (@temporal-cortex/cortex-mcp). Source code is in a private repository — this repo contains user-facing docs, setup guides, integration examples, directory configs, and the Dockerfile.

Structure

  • README.md — Main user-facing docs (Q&A format: each section is a question)
  • CHANGELOG.md — Release history
  • docs/ — Setup guides (google-cloud-setup, outlook-setup, caldav-setup), tool reference, integration guides (CrewAI, OpenAI Agents SDK), architecture overview
  • examples/ — Integration examples: crewai/, langgraph/, openai-agents/, config snippets (claude-desktop.json, cursor.json, windsurf.json)
  • Dockerfile — Multi-stage build wrapping the npm binary
  • smithery.yaml — Smithery directory config
  • glama.json — Glama directory metadata (maintainers field only; Docker config is in Glama dashboard)
  • .mcp/server.json — MCP Registry metadata
  • assets/ — Icons and logos

Build & Test

No build system — this is a docs-only repo. To verify changes:

npx markdown-link-check README.md   # check links

Ensure version numbers match across README.md, Dockerfile, and smithery.yaml.

Conventions

  • Pin npm version (@temporal-cortex/[email protected]) in Dockerfile, smithery.yaml, and .mcp/server.json
  • Do NOT pin npm versions in user-facing docs — always use @temporal-cortex/cortex-mcp (latest)
  • Keep tool counts (18), layer numbers (0-4), and tool lists in sync with the source
  • README uses Q&A format: each ## section is a question starting with "How", "What", "Can"
  • No pricing or business strategy content (public repo)

Adding Examples

Follow the pattern in examples/crewai/:

  • README.md with prerequisites, quick start, file descriptions
  • .env.example with required environment variables
  • requirements.txt for Python dependencies
  • Both Local Mode (stdio) and Platform Mode (HTTP) variants where applicable

Boundaries

  • Always: verify version numbers match across README, Dockerfile, smithery.yaml after version bumps
  • Ask first: changing tool descriptions, parameter schemas, or layer assignments
  • Never: include API keys, secrets, or pricing information

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.
