mcp-hub MCP

mcp-hub is a community-maintained MCP gateway that aggregates multiple stdio MCP servers into a single containerized HTTPS endpoint. It supports both MCP protocol revisions, provides path-based routing for individual servers, and offers a hub aggregate endpoint with meta-tools. The server handles OAuth 2.1 authentication for both clients and upstreams, ensuring secure access for tools like ChatGPT, Claude, and Cursor.
