MCP (Model Context Protocol) lets external LLM clients — Claude Desktop, Warp, Cursor, Continue — read your data through Sery. Two flavors:

Local stdio mode (Free, no account)

Toggle a folder under Settings → MCP in Sery Link. Copy the generated config snippet for your client. Paste, restart, done. Nine read-only tools — list files, search, schema, sample rows, document text, SQL — all running locally.

{
  "mcpServers": {
    "sery": {
      "command": "/Applications/Sery Link.app/Contents/MacOS/sery-link",
      "args": ["--mcp-stdio", "--root", "/Users/me/Documents"]
    }
  }
}

Or skip the GUI: cargo install sery-mcp gives you the same MCP server as a standalone Rust binary.

Cloud endpoint (Plus only)

For multi-machine workspaces, point your MCP client at https://mcp.sery.ai/sse with a workspace API key (generate one at Settings → API Keys). Same nine tools, but query_sql routes to the machine that owns the file via the WebSocket tunnel.

{
  "mcpServers": {
    "sery-cloud": {
      "url": "https://mcp.sery.ai/sse",
      "transport": "sse",
      "headers": { "Authorization": "Bearer sery_xxx" }
    }
  }
}
