Central MCP Host Overview

The Central MCP Host solves a common pain point for developers building AI‑powered applications: managing multiple Model Context Protocol (MCP) servers in a single, scalable environment. By bundling Traefik as a reverse proxy and SuperGateway for transport conversion, it allows teams to expose dozens of MCP services—such as Notion, GitHub, Linear, and a custom Memory Bank—through straightforward HTTP endpoints while keeping each service isolated in its own Docker container. This architecture eliminates the need for individual server deployments, simplifies network routing, and centralizes monitoring via Traefik’s dashboard.

At its core, the host runs a Traefik instance that listens on a single hostname and routes traffic to the appropriate MCP server based on path prefixes (, , , ). SuperGateway sits inside each service container, translating the MCP server’s standard input/output (stdio) interface into Server‑Sent Events (SSE) and message endpoints. Clients can therefore maintain long‑lived SSE connections for streaming responses while sending discrete messages over HTTP, all through the same URL space. This dual‑transport support is critical for AI assistants that need real‑time updates and fine‑grained control over tool interactions.

Key capabilities of the Central MCP Host include:

• Modular Docker Compose: Each service has its own compose file, making it trivial to start the entire stack or individual services via Docker Compose profiles. Adding a new MCP server is as simple as creating a new compose fragment and updating the main file.
• Unified Authentication: API tokens for Notion, Linear, and GitHub are injected via environment variables, keeping secrets out of the codebase while allowing each service to authenticate against its external API.
• Scalable Routing: Traefik’s path‑based routing and header manipulation ensure that requests are forwarded correctly without exposing internal container ports. The proxy also strips path prefixes, so downstream services receive clean URLs.
• Observability: Traefik’s built‑in dashboard provides real‑time insight into request latency, error rates, and traffic distribution across the MCP services, enabling rapid troubleshooting.

Typical use cases for this host include:

• AI‑driven project management: An assistant can query GitHub issues, create Linear tickets, and pull data from Notion all through a single MCP endpoint, streamlining workflow automation.
• Knowledge capture: The Memory Bank service records project notes and thought trails, allowing developers to retrieve contextual information during AI interactions without manual copy‑paste.
• Continuous integration pipelines: CI/CD systems can invoke MCP servers to trigger GitHub actions or update Linear statuses, integrating AI insights directly into release workflows.

By centralizing MCP servers behind a single, well‑documented proxy stack, the Central MCP Host empowers developers to focus on building intelligent features rather than wrestling with deployment complexity. Its modularity, transport flexibility, and built‑in observability make it a standout solution for teams that rely on AI assistants to interact with diverse external tools.
