Overview
What is WebSocket MCP?
WebSocket MCP is an implementation of the Model Context Protocol (MCP) using WebSocket transport, including a server, client, and a local LLM chat bot demo. It aims to overcome the limitations of the default stdio and SSE transport layers.
How to use WebSocket MCP?
Run uv run local-llm-server to start the server, which defaults to ws://0.0.0.0:8766. Connect a client with uv run local-llm-client --server-ip <IP> to interact with the LLM.
