RuleStack MCP

Lets an assistant search real AGENTS.md, CLAUDE.md and Cursor-style agent config files from public repositories, scored for quality.

What it does

RuleStack exposes a single search tool, search_agent_configs, which takes optional filters for stack, format, tag, minimum quality and result limit. It returns real agent configuration files such as AGENTS.md, CLAUDE.md, Cursor, Copilot, Windsurf, GEMINI.md and Cline files drawn from public repositories, each scored for quality. The intended use is seeing how maintained projects on a given stack write their own agent instructions.

When to use it

Useful when drafting or improving an agent instruction file and wanting examples from real, maintained projects on a similar stack. Also handy for comparing conventions across formats such as Cursor, Copilot or Cline before settling on one.

Requirements

Runs locally over stdio, typically launched with npx, so Node.js and network access are needed to fetch the package and query results. No API key, signup or environment variables are declared. It can also be started with the --http flag to serve streamable HTTP on a local port.
