🛡️ 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.

Key Features:

• 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.

🛠️ Available Tools

Core Tools

| Tool | Description | |:---|:---| | rigour_check | Runs all configured quality gates on the current workspace. | | rigour_explain | Explains why a specific gate failed and provides actionable fix instructions. | | rigour_check_pattern | Checks if a proposed code pattern already exists in the codebase. | | rigour_remember | Stores project-specific context or rules in Rigour's persistent memory. | | rigour_recall | Retrieves stored context to guide AI generation. | | rigour_security_audit | Runs a live CVE check on project dependencies. |

Frontier Model Tools (v2.14+)

For next-gen multi-agent workflows (Opus 4.6, GPT-5.3-Codex):

| Tool | Description | |:---|:---| | rigour_agent_register | Register agent in session with scope conflict detection. | | rigour_agent_deregister | Remove agent from session when work is complete. | | rigour_checkpoint | Record quality checkpoint with drift detection. | | rigour_handoff | Initiate task handoff to another agent. | | rigour_handoff_accept | Accept a pending handoff from another agent. |
