Use Darwin through a remote MCP connection when your ChatGPT workspace supports MCP tools. For an application built on OpenAI APIs, call Darwin from your server through the API or SDK.
Developer-mode installation works now. Darwin is not yet published in the ChatGPT Apps Directory or Codex Plugin Directory; that public listing requires OpenAI review and a separate publish action after approval.

​
Remote MCP

Add https://mcp.darwin.so/mcp, complete Darwin sign-in, and approve only the scopes the conversation needs. Verify that ChatGPT lists one Search tool and six Action tools before relying on the connection.

​
Application integration

Expose Darwin as a server-side tool to your OpenAI model. Keep the exact Search result in application state and pass its capability ID and revision to Act without asking the model to reconstruct them.
Do not place a Darwin API key in a custom instruction, conversation, browser bundle, or tool argument.
See OpenAI Agents SDK for framework guidance.
