Source Library MCP Server

Search, read, and cite 22,000+ rare pre-modern texts (alchemy, Hermetica, Kabbalah, theology, early science) with AI-generated English translations. 12 tools (full-text + semantic search, reading, exact quoting, image search, duplicate detection, feedback, sharing findings back). CLI + MCP server, no API key needed. It runs locally over stdio via the published package.

People connecting web framework tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Source Library

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add embassy-of-the-free-mind-sourcelibrary-v -- npx -y @source-library/mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "embassy-of-the-free-mind-sourcelibrary-v": {
      "command": "npx",
      "args": [
        "-y",
        "@source-library/mcp-server"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

license AGPL-3.0 - declared in the repository

npm package @source-library/mcp-server - the @source-library scope differs from the repo owner (embassy-of-the-free-mind); confirm it's the project's official package

registry namespace io.github.Embassy-of-the-Free-Mind is GitHub-verified and matches the repo owner
