Grok is xAI’s assistant, and Grok Build is its coding agent for the terminal. Connect either one to Lumx’s docs MCP server at https://docs.lumx.io/mcp, and Grok looks up endpoints, fields, and examples in the Lumx docs instead of guessing them. The docs MCP server only reads documentation. It doesn’t call the Lumx API or move money.

​
Prerequisites

​
Add the connector in Grok

  1. Go to grok.com/connectors.
  2. Click New Connector, then select Custom.
  3. Paste https://docs.lumx.io/mcp as the MCP server URL.
On Grok Business and Enterprise, an admin provisions the connector first. See xAI’s Connectors docs.

​
Add the MCP server in Grok Build

Run the following command in your terminal:
Run grok mcp list to check that lumx-docs is configured.
Grok Build also loads MCP servers from ~/.claude.json, .cursor/mcp.json, and .mcp.json. If you already added lumx-docs to Claude Code or Cursor, Grok Build picks it up.

​
Use it

Ask Grok or Grok Build:
Grok prompt
In Grok Build, keep your API key in LUMX_API_KEY in your environment or an .env file that’s gitignored, and never paste it into the chat. For full integration prompts, see the Prompt library.
