WebSocket client and server implementation for FastMCP framework
If you already use Mcpsock, the mcpsock mcp server is the piece that lets your assistant work with it directly. WebSocket client and server implementation for FastMCP framework.
MCPSock is a Python library that provides WebSocket client and server implementations for the FastMCP framework. It offers a clean, easy-to-use API for building WebSocket-based applications that communicate using the FastMCP framework.
mcpsock on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
WebSocketClient — The WebSocketClient class provides methods for connecting to a FastMCP WebSocket server and interacting with itWebSocketServer — The WebSocketServer class provides a decorator-based API for registering handlers for FastMCP messagesSetup — The Setup tool exposed by this serverPlenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Mcpsock's toolset — WebSocketClient, WebSocketServer, Setup — is a fair guide to whether it matches your workflow.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
