mcp-hub

Serve many stdio MCP servers from one container, published over HTTPS for ChatGPT connectors, Claude (Web and Code), Mistral Le Chat, Cursor, LibreChat and any other Streamable-HTTP MCP client — with a built-in OAuth 2.1 login protected by a single password, plus long-lived API tokens for clients that cannot do OAuth (OpenAI Responses API, xAI API, Gemini API). Per-client recipes: client compatibility.

Demo: config in, hub up, servers reachable through one endpoint

Why

Wrapping each stdio MCP server in its own auth-proxy container costs a full image, an OAuth stack, a hostname and a compose stack per server. mcp-hub replaces N containers with one process:

Config is exactly Claude Code's mcpServers format — copy entries 1:1.

Path-based routing: https://host/paperless, https://host/homeassistant, …

/hub aggregate: register a single connector and reach every server through 6 meta-tools (list_servers, list_tools, get_tool_schema, call_tool, wake_server, sleep_server) without flooding the model context with N×tools schemas.

Also without HTTP: mcp-hub --stdio serves that same aggregate on stdin/stdout for clients that can only spawn a local process (Claude Desktop, Codex, …) — same mcp.json, no TLS, no reverse proxy, no login. Auth exists for the network endpoints; over stdio the trust boundary is the local user.

On-demand lifecycle: stdio and docker servers start when used and sleep after 60 idle minutes, answering initialize/tools/list from a persistent snapshot meanwhile — a dozen servers cost only the memory of the ones in use. keepAlive: true exempts a server, IDLE_TIMEOUT_MINUTES=0 the hub.

Supervision: children are pinged and restarted with exponential backoff when they die. A down server answers 503, not silence; a crash-looping server nobody uses is parked instead of restarted forever.

Hot reload: edits to mcp.json start/stop/restart only the affected servers.

Stateless Streamable HTTP: no session state, so claude.ai's reconnect-without-DELETE behaviour cannot leak processes or memory.

Lightweight by design: one Node process, no database (state is one JSON file plus a JWT key under /data), a handful of runtime dep
