The persona builder. Like chat_scenario, this is a conversational loop between you and Percio’s persona assistant, with the MCP client as a strict relay. When the persona is complete, the client passes the generated data to create_persona to save it.

​
Inputs

​
Output

The assistant’s next response. Includes an isComplete boolean and, once finished, the generated persona data ready to pass to create_persona.

​
The relay rule

Same as chat_scenario: Cursor must show the assistant’s questions to you verbatim and wait for your answer. It should never invent details about the persona — only your actual words go in as role: "user" messages.

​
Typical loop

  1. Client calls chat_persona with an opening role: "user" message describing the persona you want.
  2. Assistant replies with follow-up questions — occupation, device context, pain points, tech level, etc.
  3. Client relays the questions to you.
  4. You answer.
  5. Client appends to the history and calls again.
  6. Repeat until isComplete: true.
  7. Client calls create_persona with the generated data to save the persona.

​
Example prompt in Cursor

“Create a Percio persona for a 35-year-old bakery owner who mostly uses Instagram on her phone to run her business.”
Cursor will call chat_persona with that opening line and start the Q&A.

​
When to use it

Whenever you want to create a persona without leaving Cursor — or when a scenario calls for a persona you don’t have and you want to create one on the spot.
