Agent Harnesses

Overview

Agent Harnesses is a Model Context Protocol server that provides curated agent-harness picks and decision guides, with live GitHub and Hacker News discovery through its pick_infrastructure tool. Rather than switching between apps to research frameworks and tools, you can query Agent Harnesses directly from your AI assistant as callable tools.

The server runs locally via the Python package agent-harnesses-mcp, installed with uvx agent-harnesses-mcp. It requires no authentication and works immediately over stdio. Version v0.5.1 is available under the CC-BY-SA-4.0 license, with source code at RyanAlberts/best-of-Agent-Harnesses on GitHub, where the project has 747 stars.

Agent Harnesses belongs in the AI & Agents category on mcp.site and 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 information up to date.
