Claude connector

Connect Synthesia to Claude and create videos from a chat.

Add Synthesia to Claude as a custom connector, then ask for a video draft or a Syren video without leaving the conversation. Make sure you meet the prerequisites first.

Connect a personal account

Use these steps if your Claude account isn’t part of a company workspace.

  1. Go to Settings → Connectors, select Add, then select Add custom connector.

    The Add custom connector dialog with the name Synthesia and the server URL entered

  3. Keep the detected authentication options (Sign in now and Use Claude's published identity). Synthesia authenticates through WorkOS, so you don’t need client credentials. Select Add, then follow the prompts to sign in.

  2. Select Add, hover over Custom, then select Web.

  3. Enter the server URL:

    https://mcp.synthesia.io/mcp

  4. Leave Advanced settings (OAuth Client ID and Secret) empty. Synthesia authenticates through WorkOS, so you don’t need client credentials.

  5. Select Add.

Workspace members then connect individually. Share the workspace member steps with your team.

For more on this flow, see Anthropic’s guide to custom connectors using remote MCP.

Connect as a workspace member

Use these steps if an admin has already added Synthesia as an organization-wide connector.

  1. Open Claude Desktop or the Claude web app.
  2. Go to Settings → Connectors.
  3. Find Synthesia in the list of connectors (labeled Custom) and select Connect.
  4. In the Synthesia window that opens, approve the permissions and sign in. Your session is cached, so you won’t be asked to approve every time.
  5. Confirm the Synthesia connector appears under the connectors icon in the message box.

Turn on Synthesia in a chat

  1. Start a new chat.
  2. Select the + menu and switch on Synthesia.
  3. Ask for a video. To create a Syren video, include “use Syren” in your prompt.

To create Syren videos, go to Settings → Connectors → Synthesia, expand each group under Tool permissions, and confirm the Syren tools aren’t set to Blocked.

The Synthesia connector page in Claude showing tool permissions grouped as interactive, read-only, write/delete and app-only tools

Next, see Create a video draft or Create and edit a Syren video.

Refresh the connector

If we update the server’s tool list or descriptions, refresh the connector:

  1. Go to Settings → Connectors → Synthesia.
  2. Select Refresh.

If a tool still doesn’t show up, restart the Claude desktop or web app.

On Claude’s Business plan, connectors can’t be updated after publishing. Recreate and republish the connector to pick up changes.
