How to Set Up and Use Rigour
Rigour is an MCP server that acts as a quality gate system for AI coding agents, providing automated lint, test, and build checks with persistent memory across sessions. It exposes 26 MCP tools covering security vulnerability detection (hardcoded secrets, SQL injection, XSS, CSRF), code complexity analysis, and AI-specific issues like hallucinated imports and phantom API usage. By integrating Rigour into your agent workflow, AI assistants can self-heal code quality issues without human intervention.
Prerequisites
- Node.js 18 or later with npx available
- An MCP-compatible client: Claude Desktop, Cursor, or Claude Code
- A software project with TypeScript, JavaScript, Python, Go, Ruby, C#, Java, Kotlin, or Rust code
- Optional: Claude API key (sk-ant-...) for deep AI-assisted analysis mode
Run a zero-config scan on your project
Use the Rigour CLI to perform an immediate scan of your codebase with no setup required. This identifies security issues, code quality problems, and AI-specific bugs.
npx rigour-scanInitialize Rigour quality gates
Set up persistent quality gates for your project. This creates a configuration that AI agents will check against during code generation.
npx @rigour-labs/cli initAdd the MCP server to your AI client configuration
Add Rigour to your MCP client so AI agents can call quality gate checks automatically during coding sessions.
{
"mcpServers": {
"rigour": {
"command": "npx",
"args": ["-y", "@rigour-labs/mcp"]
}
}
}Run quality gate checks
Execute all configured quality gates. Use --deep for local AI-powered analysis that provides detailed fix instructions in JSON format for agent self-healing.
npx @rigour-labs/cli check
# or with AI analysis:
npx @rigour-labs/cli check --deep --provider claude -k sk-ant-xxxLaunch the monitoring dashboard
Open the Rigour Studio web dashboard to monitor quality gate results, track issues over time, and observe agent self-healing activity.

Example instructions to give your AI agent once Rigour is connected via MCP.
- "Run rigour quality gates on this file and fix any issues you find"
- "Check for hardcoded secrets or SQL injection vulnerabilities in the codebase"
- "Detect any hallucinated imports in the Python files I just wrote"
- "Run the lint and test gates, then report any failures with suggested fixes"
- "Scan for cyclomatic complexity issues and refactor the most complex functions"Troubleshooting Rigour
npx @rigour-labs/mcp fails to start
Ensure Node.js 18+ is installed and your network can reach the npm registry. Try 'npm install -g @rigour-labs/mcp' for a global install, then set the command to 'rigour-mcp' in your client config.
Deep analysis mode returns no results
Deep mode requires a valid Claude API key passed via '--provider claude -k sk-ant-xxx'. Verify the key is active and has sufficient quota. Without --deep, basic static analysis still runs without an API key.
Memory persistence not working between sessions
Rigour stores gate state in the project directory. Ensure the working directory is consistent between sessions and the agent has write permissions to the project folder.
