MCP Hub acts as a central coordinator for MCP servers, exposing a management REST API and web UI for server administration while providing a single MCP endpoint for clients to access all server capabilities. It implements the MCP 2025-03-26 specification with support for streamable HTTP, SSE, and STDIO transports, OAuth 2.0 authentication, and real-time status updates. This enables MCP clients like Claude Desktop and Cline to connect to one endpoint and access tools, resources, and prompts from multiple managed servers.
