MCP-Hub MCP

What is MCP-Hub MCP?

MCP-Hub MCP is a hub server that connects to and manages other MCP (Model Context Protocol) servers, allowing users to list their tools and execute them. It is especially useful for bypassing Cursor’s 40-tool MCP limit and reducing AI mistakes by hiding infrequently used tools.

How to use MCP-Hub MCP?

Install via npx with the mcp-hub-mcp package and specify a config path. Configure the hub by providing a JSON configuration file (Claude Desktop format) via environment variable (MCP_CONFIG_PATH), CLI argument (--config-path), or a default mcp-config.json. Once connected, use the tools list-all-tools and call-tool to interact with all managed servers.
