Starfetch MCP Server

Starfetch gives AI agents safe, reproducible access to public astronomy catalogs through the Model Context Protocol (MCP). It runs locally over stdio via the published package.

People who work with adql, astronomy and gaia and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Starfetch

before you install - you'll need

ALLOWED_ORIGINS

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add starfetch-js-starfetch -- npx -y @starfetch-js/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "starfetch-js-starfetch": {
      "command": "npx",
      "args": [
        "-y",
        "@starfetch-js/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
