mcp-read-only-argocd: Instructions file for Codex

AGENTS.md

mcp-read-only-argocd AGENTS.md is an instructions file for Codex, OpenCode from lukleh/mcp-read-only-argocd. It costs 600 tokens per session, scanned A, original, MIT.

A repository guide for AI coding assistants working on a read-only Argo CD server. It explains the folder structure, coding rules, configuration, tests, and development commands.

In plain words
What is it for?
Use it when implementing, reviewing, testing, or troubleshooting changes to the server and its Argo CD connections.
Why use it?
It helps an assistant find the right files and follow the project's rules instead of guessing how the code is organized.

Instructions file for CodexOpenCode

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

This is lukleh/mcp-read-only-argocd's own configuration. It tells Codex and OpenCode how to work on mcp-read-only-argocd 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-read-only-argocd 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-read-only-argocd 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 8d 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.

Repository Guidelines

Project Structure & Module Organization

src/mcp_read_only_argocd/server.py is the MCP entry point and wires the domain tool modules under src/mcp_read_only_argocd/tools/. Connection parsing and token resolution live in config.py; HTTP calls and cookie rotation live in argocd_connector.py; shared error types are in exceptions.py; runtime path resolution is in runtime_paths.py; and validation helpers are in validation.py. Tests live in tests/, and smoke_test.py is the checkout-level connectivity probe for configured Argo CD instances.

Build, Test, and Development Commands

  • uv sync --extra dev installs runtime and development dependencies.
  • uv run mcp-read-only-argocd --print-paths shows the resolved config, state, and cache locations.
  • uv run mcp-read-only-argocd --write-sample-config writes the default connections.yaml; add --overwrite only when you intend to replace it.
  • uv run pytest -q runs the full test suite.
  • uv run pytest tests/test_server.py -q runs a focused test module while iterating.
  • uv run python smoke_test.py --connection staging exercises one configured connection end to end.
  • uv run ruff check src tests smoke_test.py runs linting.
  • uv run ty check runs the type checker on src/.

Coding Style & Naming Conventions

Target Python 3.11+ with four-space indentation, explicit type hints, and small focused helpers. Use snake_case for modules, functions, tests, and config keys; use PascalCase for classes and Pydantic models. Keep tool registration split by domain instead of growing server.py, and preserve the current exception-driven error flow rather than returning ad hoc error payloads.

Testing Guidelines

Pytest uses unit and integration markers from pyproject.toml; prefer unit coverage by default and reserve integration runs for live Argo CD environments. Add or update tests whenever request shaping, runtime path handling, cookie refresh, NDJSON log parsing, MCP tool outputs, or hot reload behavior changes. When touching token reload or persistence behavior, cover both YAML-configured and state-file-driven cases.

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.
