Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is akougkas/zulipchat-mcp's own configuration. It tells Codex and OpenCode how to work on zulipchat-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 zulipchat-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 C, and why

zulipchat-mcp AGENTS.md scanned grade C with 1 finding 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 9d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Repository Guidelines

Current Status (v0.7.3-beta.1)

Published: PyPI | Install: uvx zulipchat-mcp

Project Structure & Module Organization

  • Source code lives in src/zulipchat_mcp/:
    • tools/ (tool groups), core/ (client, cache, commands), services/ (listener, scheduler), integrations/ (client installers), utils/ (logging, metrics, db).
  • Tests are in tests/ (pytest with slow and integration markers).
  • Config via CLI flags or environment; copy .env.example to .env for local dev. Entry points: zulipchat-mcp, zulipchat-mcp-integrate.

Build, Test, and Development Commands

  • uv sync — install dependencies.
  • uv run zulipchat-mcp --zulip-config-file ~/.zuliprc [--enable-listener] — run server locally.
  • uvx zulipchat-mcp — quick run via uvx shim.
  • uv run pytest -q — run tests. Use -m "not slow and not integration" to skip long tests; --cov=src for coverage. Gate is set to 60%.
  • uv run ruff check . — lint; use Black on changed Python files; uv run mypy src — type-check.

Coding Style & Naming Conventions

  • Python 3.10+, 4‑space indent, Black line length 88, Ruff configured (pycodestyle, pyflakes, isort, bugbear, pyupgrade). Keep imports sorted.
  • Names: functions/variables snake_case, classes CamelCase, constants UPPER_SNAKE_CASE, modules lower_snake_case.py.
  • Tool groups should expose register_*_tools(mcp) mirroring patterns in src/zulipchat_mcp/tools/.

Testing Guidelines

  • Place tests under tests/ as test_*.py; classes Test*, functions test_*.
  • Mark long/external tests with @pytest.mark.slow or @pytest.mark.integration and gate in CI via markers.
  • Prefer fast, deterministic unit tests; mock Zulip API calls. Aim for meaningful coverage with pytest --cov=src.
  • Testing strategy: always use uv (no direct Python invocations), keep tests isolated and network-free by mocking clients, aggressively clean caches/venv before major coverage pushes (rm -rf .venv .pytest_cache **/__pycache__ htmlcov .coverage* coverage.xml .uv_cache && uv sync --reinstall), and maintain the coverage gate at 60% while adding minimal, targeted tests without altering functionality.

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.
