harmony-mcp

Overview

harmony-mcp is a Model Context Protocol server that enforces repository rules for AI agents by checking diffs against your project's conventions. It integrates directly with AI assistants, giving them tools to validate code changes and maintain consistency across your codebase.

The server runs locally on your machine via the npm package harmony-mcp, communicating over stdio. Installation is simple with npx -y harmony-mcp, and no authentication is required to get started. The latest release is v0.1.5.

You'll find harmony-mcp listed in the AI & Agents category here on mcp.site. It works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to verify ownership and keep it up to date.
