PolyMCP is a framework for building and interacting with MCP (Model Context Protocol) servers and for creating agents that can use those servers as dynamic tools.<p>Developing and managing MCP servers often involves several challenges:<p>Exposing Python functions as discoverable tools requires repetitive boilerplate.<p>Coordinating multiple MCP servers simultaneously is complex.<p>Debugging tools during development is hard due to limited visibility into calls and outputs.<p>Integrating agents with LLMs to automatically discover and invoke tools is usually ad-hoc.<p>PolyMCP addresses these challenges by providing:<p>Flexible tool exposure: Python functions can be served over HTTP, in-process, or stdio with minimal setup.<p>Inspector dashboard: Monitor tool invocations, metrics, and test calls interactively in real-time.<p>Agent integration: Support for multiple LLM providers and automatic tool discovery and invocation.<p>CLI and workflow utilities: Streamline project setup, testing, and execution.<p>PolyMCP reduces friction in MCP server development and multi-tool agent orchestration, offering a reliable framework for building intelligent, tool-driven systems.<p>Github: <a href="https://github.com/poly-mcp/Polymcp" rel="nofollow">https://github.com/poly-mcp/Polymcp</a>
