Tools and MCP connectors that fit

xAI API: xAI API only: remote MCP in the Responses API, the native SDK and the Speech to Speech API. Streaming HTTP and SSE. Not the Grok app, Grok Bot or Grok Build. docs.x.ai (opens in a new tab). These official remote MCP servers fit that rule. We have not tested each server with this model. A server that publishes a client list is left out when this lab is not on it.
