Rigour
@rigour-labs
Deterministic quality gates for AI coding agents. Rigour runs 23 automated checks on every file AI writes — structural analysis, security scanning, AI-drift detection, and agent governance.
Works as an MCP server for Claude Desktop, Cursor, and Cline. Supports TypeScript, JavaScript, Python, Go, Ruby, and C#. Forces AI agents to write production-grade code with PASS/FAIL enforcement.

# Rigour — Deterministic Quality Gates for AI Coding Agents
Rigour is an MCP server that forces AI agents to write production-grade code. It runs 23 automated quality checks on every file the agent writes, returning PASS/FAIL results that the agent must address before proceeding.
## Why Rigour?
AI coding agents (Claude, GPT, Copilot) generate code fast — but without quality enforcement. Rigour acts as a leash, not a suggestion. Every file gets scanned for:
- **Structural issues**: file size, cyclomatic complexity, deep nesting, long functions
- **Security vulnerabilities**: SQL injection, XSS, hardcoded secrets, command injection, path traversal
- **AI-drift patterns**: duplicated functions across files, hallucinated imports, context window quality degradation, inconsistent error handling
- **Agent governance**: retry loop breaking, checkpoint enforcement, environment alignment
## Two-Score System
Every scan produces:
- **AI Health Score** — measures AI-specific code quality (drift, hallucinations, async safety)
- **Structural Score** — measures traditional code quality (complexity, size, patterns)
Both scores use severity-weighted deductions: critical issues cost 20 points, high costs 10, medium costs 5.
## Quick Start

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