What is the MCP Gateway MCP server?

If you want an AI assistant working directly with MCP Gateway, the mcp gateway mcp server is the bridge. The MCP gateway is a reverse proxy server that forwards requests from clients to the MCP server or uses all MCP servers under the gateway through a unified portal.

What MCP Gateway does

The MCP gateway is a reverse proxy server that forwards requests from clients to the MCP server or uses all MCP servers under the gateway through a unified portal.

Key capabilities

  • Deploy multiple MCP servers
  • Connect to MCP server
  • Use gateway to call MCP servers
  • Get all MCP servers' SSE streams
  • Get all MCP servers' tools
  • Streamable HTTP aggregated endpoint with session management via Mcp-Session-Id header
  • Dynamic capability aggregation (gateway only advertises capabilities that at least one downstream MCP supports)
  • MCP OAuth 2.1 resource server authentication with Protected Resource Metadata discovery

Tools it exposes

Once connected, the assistant can call this tool directly:

  • Deploy — support: uvx, npx. or sse url http POST /deploy HTTP/1.1 Host: localhost:8080 Content-Type: application/json

Installing the mcp gateway mcp server

The server is distributed via a container image as ghcr.io/lucky-aeon/mcp-gateway, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Configuration

Before the server will start you need to supply 2 environment variables: KEY1, KEY2. Keep credentials in your client's env block or a secrets manager rather than committing them.

Where it fits

Cloud and DevOps servers put infrastructure on speaking terms with your assistant, so "why is this broken?" is answered from real state rather than a generic checklist. MCP Gateway sits in that group, and the shape of its toolset — Deploy — tells you what it is really for. Worth comparing against the other cloud devops servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • It will not start until its required credentials are present, so set those before wondering why the tools never appear.
  • Maintained by lucky-aeon.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the mcp gateway mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

Frequently asked questions

It connects MCP Gateway to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (Deploy) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with MCP Gateway directly.
