Getting started
Install the server and connect your agent.
rule-mcp
v0.1.3GitHub
Deterministic skills for every AI coding agent, without calling an LLM.
rule-mcp is an MCP server. It sends a free-text request to the correct skill. It serves styleguides and templates as tools and resources. It checks generated code with guardrails. It runs on your machine and works with any model.
- Node 24+
- 82 skills
- 105 tools
- 172 resources
- 41 prompts
- 44 slash commands
How it works
- Route. The router reads a free-text request and selects a skill or an area hub.
- Serve. The skill gives its evidence as MCP tools, resources, and prompts.
- Validate. Deterministic guardrails check the generated code before you keep it.

What the server does
rule-mcp is one MCP server that runs on your machine and serves deterministic skills to any coding agent. It reads a free-text request, routes it to the right skill, and returns that skill's evidence as tools, resources and prompts. Guardrails then check the generated code against the rules the skill states. No model is called to route, to serve or to validate, so the same request returns the same answer at no token cost. What the server records stays in one directory on the machine, with an off switch, and it sends the prompt nowhere else.
