Supertest MCP server

Supertest runs AI-moderated user interviews. Connect this server and your AI client can write a study, launch it, and read back what participants said.

Your AI client
claude mcp add --transport http supertest …

Then run /mcp in Claude Code and authenticate with the Supertest MCP server.

  1. Go to Plugins and choose “Add custom MCP server”, from the + button or from Browse directory → Add at the top right. If neither is there, turn on developer mode in ChatGPT’s settings.
  2. Name it Supertest, paste …, and pick OAuth. Accept the warning, create it as a plugin, and sign in with your Supertest account.
  3. In a new chat, type @ and pick Supertest.

Add an MCP server to Lovable using the following configuration. Leave the authentication method set to OAuth.

Name…
Server URL…

Open the Lovable MCP form

Once it is added, set its tools to “Always allow”, or Lovable asks you to approve every call.

Add a remote server over Streamable HTTP at … and authenticate with OAuth. The server registers your client automatically.

Run a Supertest

Tell your agent what you want to learn from your users, with the word “supertest” in it. Plain “test” is not enough: Lovable takes “Let’s test this” as a request to run its own checks. To test something you built, open the agent in its project, or give it the link.

  1. Your agent asks about your product and your users, then suggests a few studies, and you pick one. Each is either a conversation with participants, or one where they use your app or site while they talk. Say “Supertest my app” and it skips straight to that.
  2. For an app or site, it agrees one task with you and labels the buttons and fields the task uses in your code. Except in Lovable, it asks whether to upload the app or use an address where it is already live. An upload is hosted by Supertest, and participants can read everything in it, so it must hold no secrets.
  3. Your agent writes the interview questions, and you get a preview link: one interview for you to take yourself. You need a microphone, it does not count as a participant, and you can change the interviewer’s voice and pace in it.
  4. Your agent asks how the preview went and reads it, so you can change things and preview again. When you are happy, ask it to publish: it gives you a link, and each person who opens it gets their own interview. Ask your agent to read their interviews, and a summary across them, as they come in.

Only have the address of a live site? That works too: the interviewer knows which page participants are on, but not what they press.

No app yet? Your agent can run a voice-only study instead, or build a simple app first and supertest that.
