Rigour MCP Server

Your coding agents write code. Rigour makes the codebase learn. Rigour is a local-first engineering intelligence layer for coding agents. It gives agents the smallest useful context, enforces deterministic boundaries around observable work, and turns verified outcomes into reusable knowledge for the next task.

People who work with agentic workflow, code quality and developer productivity and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Rigour

Claude Code

claude mcp add rigour-labs-rigour -- npx -y @rigour-labs/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "rigour-labs-rigour": {
      "command": "npx",
      "args": [
        "-y",
        "@rigour-labs/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
