Connect Thirdfy in Claude

Add Thirdfy to claude.ai in four steps, sign in, pick your agent and ask your first question. With screenshots.

Add Thirdfy to Claude once. Then your agent reads markets and trades for you when you ask in plain words. It takes about two minutes.

What you need: a Claude plan with custom connectors (Free, Pro, Max, Team or Enterprise) and a Thirdfy account. You can create the account while you connect.

1. Add the connector

In claude.ai, open Customize → Connectors. Click + Add, then Add custom connector.

The Connectors page in claude.ai with the Add menu open on Add custom connector

Name it Thirdfy and paste this URL, then click Continue:

https://mcp.thirdfy.com/mcp

The Add custom connector dialog with the name Thirdfy and the URL https://mcp.thirdfy.com/mcp

Claude sees that Thirdfy uses sign-in. Leave the options as they are and click Add.

2. Sign in and pick your agent

Click Connect. Claude opens the Thirdfy sign-in page.

Sign in with email, Google or a wallet, the same way you do on thirdfy.com. Pick the agent Claude acts for, or click Create a new agent. Tick Trade within your agent's limits if you want Claude to place trades; leave it off to only look. Click Approve.

The Thirdfy consent page: Claude wants to connect to your Thirdfy agent, with the agent list, Read, Trade and Stay connected, and Approve

3. Ask your first question

Start a new chat and ask in plain words:

Using Thirdfy, list the venues my agent can trade on and check whether my Hyperliquid venue is ready. Read only, don't trade.

The first time Claude uses a Thirdfy tool, it asks you. Click Allow once, or Always allow for that tool.

Claude asking for approval: Claude wants to use Get provider actions from Thirdfy, with Deny, Always allow and Allow once

Claude answers with what each venue still needs.

Claude's answer: Hyperliquid is not ready because it needs a deposit, followed by a table of venues and what each still needs

Before any trade, Claude shows you a preview and runs it only when you confirm. Your agent's limits apply to every trade.

4. See or end access

Every app you connect is listed at auth.thirdfy.com/connections. Click Revoke to end Claude's access at once.
