What is the Galley MCP MCP server?

Galley mcp mcp server connects Galley MCP to AI assistants that speak the Model Context Protocol. A Model Context Protocol (MCP) server for Galley GraphQL API integration using Apollo MCP Server with mandatory automatic schema introspection. The server introspects your Galley GraphQL schema on startup and provides seamless integration with MCP clients like Claude, Cursor, and VS Code.

What Galley MCP does

A Model Context Protocol (MCP) server for Galley GraphQL API integration using Apollo MCP Server with mandatory automatic schema introspection. The server introspects your Galley GraphQL schema on startup and provides seamless integration with MCP clients like Claude, Cursor, and VS Code.

Tools it exposes

Once connected, the assistant can call these 5 tools directly:

  • Rover — Apollo's GraphQL CLI tool for schema introspection
  • Prerequisites — The Prerequisites tool exposed by this server
  • macOS — The macOS tool exposed by this server
  • Windows — The Windows tool exposed by this server
  • Debugging — The Debugging tool exposed by this server

Installing the galley mcp mcp server

The server is distributed via a container image as public.ecr.aws/o0r1r5q2/galley-mcp, 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 5 environment variables: X_API_KEY, X_USER_API_KEY, GALLEY_AUTH_TOKEN, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY. Keep credentials in your client's env block or a secrets manager rather than committing them.

Requirements

  • Docker installed on your system - Galley API authentication (X-API-KEY or Bearer token) - Network access to Galley GraphQL endpoints

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Galley MCP sits in that group, and the shape of its toolset — Rover, Prerequisites, macOS among others — tells you what it is really for. Worth comparing against the other developer tools 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 galley-solutions.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the galley mcp 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.
