Title: Connect Grok Description: Add OpenPost as a custom Grok connector. Canonical: https://docs.openpo.st/mcp/grok Source: [https://docs.openpo.st/mcp/grok](https://docs.openpo.st/mcp/grok) # Connect Grok Grok can connect to OpenPost through a custom remote connector. Use a Grok account with access to custom connectors and an OpenPost account. ## Add the connector 1. Open [Grok Connectors](https://grok.com/connectors). 2. Choose **New Connector → Custom** and name it `OpenPost`. 3. Enter `https://app.openpo.st/mcp` as the server URL. 4. Complete the supported sign-in flow. For OAuth, sign in to OpenPost and choose read-only or full access. If configuring a bearer header instead, use an OpenPost developer token with the matching MCP scope. ## Check the connection Enable OpenPost in your conversation and ask, “List my OpenPost workspaces.” Name a workspace, then request a schedule review without making changes. ## Grok Build CLI Grok Build is a separate client. Add its connection with: ```sh grok mcp add --transport http openpost https://app.openpo.st/mcp ``` Complete OAuth when prompted. A Grok web connector does not configure the CLI automatically. ## If it does not connect Grok's cloud connector needs public HTTPS. A self-hosted LAN address or `localhost` is not reachable from Grok web. Check access to custom connectors and reconnect if authorization expires.
