🛡️ Rigour MCP Server

The Quality Gate for AI-Assisted Engineering.

Rigour is a local-first Model Context Protocol (MCP) server that forces AI agents (Claude, Cursor, Windsurf, etc.) to meet strict engineering standards before marking tasks as complete.

🚀 Overview

Rigour moves code quality enforcement from the "Post-Commit" phase to the "In-Progress" phase. By running as an MCP server inside your editor, it provides the AI with a deterministic PASS/FAIL loop, preventing "Vibe Coding" and broken builds.

$3

- Quality Gates: Deterministic checks for file size, complexity, and hygiene.
- Context Memory: Persistent memory that tracks project rules and patterns across sessions.
- Pattern Reinvention Blocking: Warns or blocks the AI when it tries to rewrite existing utilities.
- Security Audits: Real-time CVE detection for dependencies the AI is suggesting.
- Zero Cloud: 100% local analysis. Your code never leaves your machine.
