Set up the connection

1

Add the SuprSend MCP server

Go to grok.com/connectors, click New Connector, and select Custom. Paste https://mcp.suprsend.com/mcp as the MCP server URL.On Grok Business and Enterprise, a team admin must provision the connector first.
2

Sign in with your SuprSend account

Complete the sign-in when Grok asks. Sign in with your SuprSend account. Your role decides the tools: admins get every tool, and members get read-only tools except the two that show sent message content, messages_get_content and messages_preview_content.
3

Verify the connection

In a new chat, ask:
Grok answers with your SuprSend workspaces.

​
Pin a workspace and restrict tools

By default, Grok and Grok Build can use every workspace and tool your role allows. To keep them on one workspace, or to give them only the tools a job needs, use one of these URLs when you add the server:
  • Pin a workspace by adding its slug to the path. The agent then can’t switch to another workspace:
  • Restrict tools with ?tools=, a comma-separated list of tool names or groups:
See Scope the connection for every URL pattern, and the tool list for every tool.

​
Troubleshooting

Run grok mcp doctor suprsend. It checks the server’s configuration and connection, and tells you what to fix.
Check the workspace slug in the URL. It must match a workspace in your SuprSend account exactly, for example staging, not the workspace’s display name. A slug that doesn’t exist fails with 403 workspace_forbidden. To see your slugs, remove the slug, reconnect, and ask: “List my SuprSend workspaces.”
