MotherDuck MCP Server

Create or sign in to a MotherDuck account via MotherDuck. Then add the remote MCP server https://api.motherduck.com/mcp in your MCP client; MotherDuck documents that clients like Claude, ChatGPT, Cursor, Claude Code, and GitHub Copilot open a browser and authenticate automatically through OAuth during connection setup in Connect to the MotherDuck MCP Server.

In the MotherDuck UI, open your organization menu, go to Settings, click + Create token, choose a token type (Read/Write or Read Scaling), optionally set an expiry, then copy the token. For service accounts, an org Admin can create the service account in Settings → Service Accounts and then create a token there; the walkthrough is in Create and configure service accounts. Store the token securely; for DuckDB clients MotherDuck recommends setting motherduck_token in your environment.
