Takes the persona data produced by chat_persona and saves it to your Percio account. Once created, the persona is immediately available for test runs in both the web app and the agent.

​
Inputs

Every field maps directly to the persona fields in the web app — see Creating personas for the full field guide.

​
Output

The saved persona, including its new UUID, plus a ready-to-use CLI command for running a test with it:

​
When to use it

  • After a chat_persona loop returns isComplete: true, to save the generated persona.
  • Directly, if Cursor has enough structured input to skip the conversation.

​
Cost

Creating a persona is free. It does not consume credits.

​
Typical MCP flow

  1. User asks Cursor to create a persona.
  2. Cursor calls chat_persona and relays the Q&A.
  3. When the conversation returns isComplete: true, Cursor calls create_persona with the generated data.
  4. Cursor confirms the persona was saved and optionally offers to run a test with it.
