Link Gemini to Trilly

The Gemini app can add an app like Trilly by its address, for now only in the US. Then you can say "find a free skill on Trilly for my budget and add it".

Steps

  1. Copy Trilly's address

    Copy Trilly's address from the box below. You'll paste it in a moment.

    https://trilly.io/api/mcp

    No key or password to copy: Trilly asks you to log in and say yes.

  2. Open Connected Apps

    On gemini.google.com, choose Settings, then Connected Apps. Don't see it? Choose Personal Intelligence, then Connected Apps.

  3. Add Trilly

    Under Custom apps, choose Add a custom app. Paste the address and choose Next. Leave Advanced features as they are: Trilly doesn't need them.

    From Google's help: Gemini's Add a custom app box, with Address https://trilly.io/api/mcp. Paste the address, then choose Next.
  4. Log in or join free, then say yes

    Trilly opens. New here? Choose Join free and confirm your email: the link in the email brings you straight back. Check what Gemini will be able to do, then choose Yes, link Gemini.

    On Trilly, the link screen: Gemini wants to link to your Trilly account. It will be able to: Find skills, and add or remove the ones you choose; Tell Trilly when a skill is used, so its numbers stay honest. Never your conversations; Use your name, business details and brand in what skills make, and save what you tell it, and ask your workspace's approvers for a yes before a letter goes out (they're told). Then the button Yes, link Gemini.
  5. Add your first skill

    In a chat, type @ and pick Trilly. Then ask: "find a free skill on Trilly for my budget and add it".

Then: Ask as you normally would. Want it to use your email or calendar? Connect them in Gemini first.

If something goes wrong

I don't see Custom apps

Google only offers it to people 18 or over in the US, on a personal account with Keep Activity on. Otherwise, download a skill and add it by hand: see Can't link?, under What you need.

Trilly says it can't check who made the app

Trilly only names apps it can recognise for certain. Before you say yes, check the address it will send you back to belongs to Google.

Checked against Gemini Apps Help: connect custom apps on 17 October 2026. See your linked apps, and unlink them, in Settings, Linked AI apps.
