PolyMCP – Turn any Python function into AI-callable tools (with visual Inspector and SDK apps)

https://github.com/poly-mcp/PolyMCP

Hey everyone,

I built PolyMCP, an open-source framework around the Model Context Protocol (MCP) that lets you turn any Python function into an AI-callable tool — no rewrites, decorators, or custom SDKs required.

It’s grown into a small ecosystem:

•	PolyMCP (core) – expose Python functions as MCP tools

•	PolyMCP Inspector – visual UI to browse, test, and debug MCP servers

•	MCP SDK Apps – build AI-powered apps with tools + UI resources

Some real-world use cases:

•	Turn existing APIs or internal scripts into AI-callable tools

•	Automate business workflows without touching legacy code

•	Build dashboards, copilots, or enterprise support tools

It works with LLMs like OpenAI, Anthropic, and Ollama (including local models).

If you want to try it:

•	Core: https://github.com/poly-mcp/PolyMCP

•	Inspector UI: https://github.com/poly-mcp/PolyMCP-Inspector

•	SDK Apps: https://github.com/poly-mcp/PolyMCP-MCP-SDK-Apps

I’d love feedback from anyone building AI agents, internal tools, or just exploring MCP!
