Rules MCP

A local MCP server that lets an assistant evaluate rules, skills and knowledge files for Cursor, Claude, VS Code and Antigravity.

What you can do

Evaluates rules, skills and knowledge content for AI coding assistants such as Cursor, Claude, VS Code and Antigravity, per the registry description. Reads rule, skill and knowledge directories, whose locations can be overridden by environment variables. Applies an active agent profile (default, cursor, claude and others) and supports a legacy YAML rules directory alongside Markdown/MDC skills. Writes logs to stderr at a configurable log level. No individual tools are listed in the manifest, so the exact operations are not documented.

When to use it

Useful when you maintain rule, skill or knowledge files for several AI coding assistants and want an assistant to evaluate them against a chosen agent profile. Best suited to local desktop setups where those files already live on the machine.

Requirements

Runs as a local stdio process installed from the npm package @akr1166org/rules-mcp, so Node.js is needed. Optional environment variables set paths and behavior: KNOWLEDGE_PATH, SKILLS_PATH, RULES_PATH, PROFILES_PATH, PROFILE and LOG_LEVEL. No authentication is declared. Desktop only; not available as a web executable.
