Choobyu MCP Server

Connect Claude and other AI agents directly to Choobyu — verified, structured topic databases built for AI consumption. Aircraft specs, FAA data, pharmaceuticals, medical devices, microcontrollers, app processors, metals, minerals, polymers, battery chemistries, sensors, and more — all queryable as native tools, no custom integration needed.

Every record includes a confidence score, source URLs, and a one-line llm_summary an agent can use directly in a response.

Quick start (Claude Desktop)

Get an API key at choobyu.com (free Explorer tier available), then add this to your Claude Desktop config:

Windows: %APPDATA%\Claude\claude_desktop_config.json Mac: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "choobyu": {
      "command": "npx",
      "args": ["-y", "choobyu-mcp"],
      "env": {
        "CHOOBYU_API_KEY": "cho_live_your_key_here"
      }
    }
  }
}

Fully quit and reopen Claude Desktop. You'll see the Choobyu tools available.

Works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, Windsurf, and others) — same command and env var everywhere.
