Access follows your account, not the connection: upgrade and the same connection sees more on its next question.

Founders

The people behind the tools. Free accounts search public profiles; members search every founder behind a tool, with enrichment, and can ask for contact details one founder at a time. The watchlist is wider: founders we follow before they have listed anything.

On request means your assistant asks for one founder's contact details on purpose, never in a list. Up to 50 a day, and every lookup is logged.

Help

“localhost refused to connect” after approving
Your app stopped waiting before you finished. Start the connection again from the app and approve within a minute or two.
The sign-in email opened a different browser
Approve there. If the app then keeps waiting, start again and open the email link in the browser your app opened.
The app can’t reach the server
Use the address exactly as shown, with www and ending in /api/mcp.
Results look limited
Ask your assistant to run my_access: it shows your plan, what you approved and today's usage.
Disconnecting an app
Every connected app is under Connected apps on your account. Disconnect, and it stops on its next question.
What you approve
  • catalog:read — Search early.tools: tools, founders, resources and blog posts, at your membership level
  • account:read — See your own listings, with their views and clicks
  • submissions:write — Check whether a product is already listed, and start a submission you finish and pay for on early.tools
  • The first is required; untick the others on the approval screen. Nothing is ever paid for from an assistant.
