PolyMCP – A framework for structuring and orchestrating MCP agents

I’ve been working on PolyMCP, an open-source framework designed to make it easier to build and coordinate agents using the Model Context Protocol (MCP).

Most MCP tooling today focuses primarily on exposing tools. PolyMCP instead targets the agent layer: how to structure agents properly, connect them to multiple MCP servers, and make them reliable in real-world workflows.

PolyMCP provides: • A clean way to implement MCP-compatible tool servers in Python or TypeScript • An agent abstraction that can connect to multiple MCP endpoints (stdio, HTTP, etc.) • Built-in orchestration primitives for handling multi-step tasks • A CLI to scaffold projects and run an inspector UI to debug tools and agent interactions • A modular architecture that makes it easier to compose skills and reuse components across projects

The goal is to reduce ad-hoc glue code between models and tools. Instead of manually wiring everything together for each new setup, PolyMCP offers a structured way to: • Register tools as MCP servers • Attach them to one or more agents • Explicitly manage execution flow and state • Inspect and debug interactions

It’s MIT licensed and aimed at developers building production-grade automation, internal copilots, or multi-tool assistants.
