CloneAI for Agents MCP
An MCP server that enables AI agents to conduct synthetic-persona surveys using 1,000 fictional Japanese personas. It allows agents to define survey questions, target specific demographic segments, and retrieve simulated responses for hypothesis testing and pretests without involving real human respondents.

cloneai_synthetic_persona_survey — Run Japanese Synthetic Persona Survey (In-Call Wait + Agent Hub Recall)
Run a free response simulation across 10-100 synthetic Japanese personas (up to 3 questions). This result is a response simulation by synthetic personas. It is not a survey of real people and does not represent public opinion. In one call: submits the survey, waits up to 30s for completion while recalling related public Agent Hub entries in parallel. Returns status "succeeded" with survey_result, or "running" with next_tool. Requires accept_terms: true. Save api_key_secret; new registration without a key is limited to 3 per IP per day.
