Fast Insight

Connect Your MCP Client

Add the Fast Insight MCP server to Claude, ChatGPT, or Codex and sign in with OAuth.

On this page

For every client below: after adding it, click Connect, sign in to Fast Insight when asked, click Allow, and start chatting.

ChatGPT

In ChatGPT go to Settings → Apps → Advanced settings, turn on Developer mode, then use Create app to register this URL and connect.

https://fastinsight.ai/api/public/mcp

Claude

This link opens Claude's add dialog with the name and URL already filled in:

Add Fast Insight to Claude

Or, in Claude go to Customize → Connectors → Add custom connector, paste the server URL above, click Connect, then sign in and allow access.

Prefer to work in plain English? Add the Fast Insight research skill on top of the connector to create, launch, and analyze studies without handling the tools yourself. Upload it under Settings → Capabilities → Skills in Claude.

Codex

  1. Open a terminal

    Open your terminal.

  2. Add the server

    codex mcp add fastinsight --url https://fastinsight.ai/api/public/mcp

  3. Sign in

    Sign in to Fast Insight in the browser, allow access, and start using it.

Server URL

https://fastinsight.ai/api/public/mcp

The server uses stateless Streamable HTTP: each request is independent, and there are no long-lived MCP sessions to manage.

First-time sign-in

  1. Discovery

    Your MCP client finds the OAuth details from the server on its own.

  2. Redirect

    You are sent to https://fastinsight.ai/api/oauth/authorize (or asked to sign in first).

  3. Consent

    The consent screen shows which app is asking for access and what it will be allowed to do.

  4. Allow

    Once you allow it, the client receives an access token and a refresh token.

Token lifetimes

Access token1 hourRefreshed automatically by the client

To disconnect, remove the MCP server from your client, or disconnect it under Account settings, "Connected AI tools" (it stops working immediately).

Permissions

When you approve access, the MCP integration can:

  • View studies and their details in the workspaces you belong to
  • Read transcripts and reports from those studies
  • Create draft studies and set their targeting
  • Start recruitment (panel recruitment starts only after you review the cost and approve it in Fast Insight)

The integration acts as you and respects the same permissions as the web app. It only sees studies you can already access.
