WebSocket MCP Wrapper
MCPOpen Source39.9
by nick1udwig • Messaging & Collaboration
Wraps MCP stdio servers with a WebSocket layer to expose MCP servers over the network for use with agents and tools like kibitz.
Example Use Cases
- 1
Access local MCP stdio servers remotely via WebSocket so they can run system operations or fetch web data over a network connection.
- 2
Serve multiple MCP servers concurrently (e.g., wcgw and fetch) and manage them via a single configurable host and port.
- 3
Bootstrap MCP servers with environment variables or custom commands (including npx or uvx commands) and expose them to web clients or orchestrators.
Description
ws-mcp launches and exposes MCP (Model Context Protocol) stdio servers over WebSocket, allowing MCP servers (e.g., wcgw, fetch) to be served remotely and accessed by web clients or agents. It integrates with the uv/uvx toolchain, supports configuration via JSON or command-line commands, environment variables, and multiple servers on configurable ports. This makes it easy to host and combine existing MCP servers and provide them to agents that speak MCP over WebSocket without modifying the servers themselves.
