Add 13F.ai to your AI › Grok

Add 13F.ai to Grok.

A few minutes. Works on a free 13F.ai account. Works today

Which plan you need
Free account. With a free 13F.ai account Grok gets the Congress data (trades, members, bills, votes and PAC donations), executive-branch trades, and FINRA short interest and short volume. Premium adds every other dataset. Grok Bot, xAI's agent, is not covered by the free plan and needs Premium.

  1. Add a custom connector

    Go to grok.com/connectors. Click New Connector, then choose Custom. Enter this server address:

    https://13f.ai/api/mcp

    No API key and no header: 13F.ai registers Grok automatically.

  2. Sign in and approve

    After you enter the address, Grok opens a 13F.ai page: sign in if asked, check that it names Grok and sends you back to grok.com, then click Approve. Grok can now read 13F.ai data for you. It can't change anything, and it never sees your password.

  3. Ask in Grok

    Ask in plain English and mention 13F.ai, for example: “Using 13F.ai, which members of Congress traded NVDA this year?”

    Naming 13F.ai helps Grok pick the connector. Without it, Grok may search the web first. Answers that come from 13F.ai link to 13f.ai, the SEC, the House or the Senate.

Try these first

All three work on Basic.

Grok Business and Enterprise

On a team plan, an admin may have to add the connector first. In the xAI console (console.x.ai), the admin selects the team, opens Grok Business, then Connectors, clicks + Add Connector, chooses Other and enters the server address above. Members then connect their own accounts at grok.com/connectors.

Trouble, or disconnecting

Having trouble? Check that the address is exactly https://13f.ai/api/mcp. A message that you need the Premium plan means you asked for something outside the free data (trades, members, bills, votes and PAC donations, FINRA short interest and short volume), or your trial or subscription isn't active: see pricing. Still stuck? Write to support@13f.ai.

Disconnecting. Go to grok.com/connectors, find 13F.ai in your connected list and disconnect it. To end the sign-in itself, remove the app from the Connected apps list on your account page. It stops working within about a minute.

These steps follow xAI's documentation on connectors in Grok. Menus move from time to time, so a name may differ slightly in your version.
