You can connect your local MCP servers to Grok as a custom MCP connector through Warplet. This lets Grok use your local apps directly from your chats.
Before you start, make sure Warplet is running and connected. The app lists one URL per MCP server under Use these URLs to connect your favorite LLM. Each URL routes to a specific MCP server: the DEVONthink URL routes to the DEVONthink MCP server, the Beeper URL to the Beeper MCP server, and so on. Copy the URL for the server you want to connect.

Follow these steps:
-
Navigate to your Grok connectors page: https://grok.com/connectors.
-
Click New Connector.
-
Choose Custom.
-
A form will appear. Fill it out with the following details:
- Name:
Warplet(or the name of the app you're exposing) - Server URL: your Warplet MCP URL, copied from the app
- Name:
-
Click Add Connector to save the new connector.
-
When Grok asks you to authorize the connector, follow the redirect to the Warplet authorization page, paste the bearer token shown in the Warplet app, and approve.
Once connected, you can use your local tools directly within Grok by asking it to use your connector in conversation.
