MCP-first persona testing

Know what your audience
thinks. Before you ship it.

Polis simulates a realistic synthetic audience across a multi-model swarm and returns who reacted how, the friction that lost them, and a rewrite that lands. One MCP tool call, not a guess.

Hand this to your agent — it does the rest

Set me up with Polis end to end. Fetch https://polis.ai/llms-full.txt and follow the "Instructions for LLM agents" section: provision an API key (if you already know my email, use it for sign up; otherwise ask me for it before continuing), give me the Stripe checkout link to approve a subscription (Starter is $5/mo), connect to the Polis MCP server, then run a persona test on the content I give you and summarize the report.

Prefer a terminal? One line provisions a key and a checkout link:

  3. Estimate, then test. polis_estimate prices the run; polis_test starts it.
  4. Poll, then read. polis_status until done, then polis_report for the deliverable.
