MCP Host CLI

🚀 mcp-host-use

mcp-host-use is a Node.js-based Model Context Protocol (MCP) host application used to connect and manage multiple MCP servers. The Host provides a unified interface that allows clients to interact with multiple MCP servers through the HTTP API, accessing and invoking tools (or resources). You can use it to quickly test and run your MCP Servers.
