MCP Supergateway Hub
Self-hostable hub that wraps stdio MCP servers as streamable HTTP endpoints via supergateway, so a fleet of Model Context Protocol servers can run on one machine and be reached from any MCP client over the network.
Open the source and read safety notes before installing.
Safety notes
- Bridges stdio MCP servers to HTTP and exposes them on your network, so each wrapped server's tools become reachable over HTTP — run it on a trusted network or behind authentication, not on a public interface.
- Running dozens of servers behind one host broadens the tool surface available to any connected client; use the --only/--exclude flags to scope what is exposed.
Privacy notes
- The gateway process and its .env hold API keys and see traffic passing between MCP clients and the wrapped servers.
- Fully self-hosted, so data stays on your own infrastructure rather than a third-party service.
Prerequisites
- Node.js 22+ (the gateway runs as a Node process; an optional systemd unit is provided for always-on use).
- Python 3.10+ with uv for uvx-based servers, Docker for the docker server, and the Quint CLI for the formal-verification server.
- API keys/connection strings in a local .env for any servers that authenticate against external services.

Editorial notes
MCP Supergateway Hub is relevant to HeyClaude users who self-host MCP infrastructure. It uses supergateway to bridge stdio MCP servers to streamable HTTP endpoints (one sequential port per server, starting at 3170), so a large set of Model Context Protocol servers — 62 are included across tiers like core dev, databases, cloud/infra, and AI bridges — can run on a dedicated machine and be reached from any MCP client. It ships a systemd unit for always-on operation and pairs well with Claude Code's Tool Search, which keeps the cost of many configured servers low.
