Experimental support.

Confirmed as of July 13, 2026

Prerequisites

• A ChatGPT account — any plan works, including free.
• You need a Valency account. Sign up here if you haven't already.

1. Open ChatGPT's Security and login settings — or navigate there manually: in ChatGPT, open Settings, then Security and login

2. Scroll down and toggle on Developer mode

3. Open this link to go straight to the connector form — or navigate there manually: close Settings, then open Plugins and press +

4. Enter the name:

   Valency

5. Enter the description:

   Infrastructure for Agentic Science

6. Enter the URL:

   https://labs.valency.io/mcp

7. Check "I understand and want to continue", then click Create

8. After a few seconds, a sign-in window appears. Sign in with Google or email

   Note

   Sign in with the email you used to register at app.valency.io. It does not have to match the email on your ChatGPT account.

   Taking a while?

   Setting up the connection can take a few seconds, and it occasionally times out. If the sign-in pop-up doesn't appear—or the connection fails—just try again. We're actively improving this.

9. In the composer, click the tools menu and enable Valency

   

10. Ask: "Search for papers about attention mechanisms in transformers" (more prompt ideas)

Success: You see paper results, and can also explicitly invoke Valency tool calls.
