Grok supports two HeyGen connectors. Add HeyGen as a custom connector to generate avatar videos, and add HyperFrames by HeyGen — an official, listed connector — to render programmatic HTML video. Both authenticate with OAuth and draw on your existing HeyGen plan’s credits — no API key required.

​
Prerequisites

  • A Grok account with connector support (custom connectors require a paid Grok plan)
  • A HeyGen account (Creator plan or above recommended for full video generation access)

​
Connect HeyGen (Custom Connector)

HeyGen isn’t listed in Grok’s connector directory yet, so add it as a custom connector with the remote MCP server URL.
1

Open the connector menu

In the Grok prompt bar, click + → Add connector.
2

Choose Custom

In the New Connector dialog, select Custom — Add your own custom connector.
3

Enter the HeyGen MCP endpoint

Set Name to HeyGen and Server URL to the remote MCP server URL, then click Add Connector:
4

Authenticate with OAuth

Click Connect and sign in to HeyGen to approve access. This one-time OAuth flow links the connector to your account.
For the full set of tools this unlocks — video generation, avatars, voices, translation, lip-sync, and more — see the MCP overview.

​
Connect HyperFrames (Official Connector)

HyperFrames is an official connector in Grok’s directory, so there’s nothing to paste — just search for it.
1

Open the connector directory

Click + → Add connector to open the New Connector dialog.
2

Search for HyperFrames

Type hyp in the search box. HyperFrames by HeyGen appears under Productivity — select it.
3

Connect

Click Connect and approve access via OAuth to link HyperFrames to your account.
Once connected, ask Grok to build and render a programmatic video project — HyperFrames turns a self-contained HTML composition into an MP4, WebM, or MOV, ideal for motion graphics and data-driven visuals. See the HyperFrames guide for what it can produce.

​
Usage

Open a new Grok chat and prompt a request. For example:
Grok calls the connector’s tools to handle scripting, avatar selection, rendering, and more. Completed HeyGen videos are also accessible from the Projects page in your HeyGen dashboard.
