Install Grok Build in Claude Code, Cursor or VS Code

Runs npx -y grok-build-mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add grok-build-mcp-server -- npx -y grok-build-mcp-server
Add to Cursor

What the publisher says

From the Grok Build repository's README, as published. We do not edit it. Read it on GitHub

grok-build-mcp-server

An MCP stdio server that exposes the Grok Build CLI (grok) as tools you can call from Claude Code, Cursor, VS Code, or any other MCP client.

Claude Code  ──stdio/MCP──▶  grok-build-mcp-server  ──spawn──▶  grok CLI  ──▶  xAI API

It is a thin process wrapper. It does not reimplement agent logic and does not talk to the xAI API directly — all the intelligence stays in the grok CLI. What this server adds is faithful argument construction, robust process supervision, and clean MCP-shaped output.

Status: 0.2.2. The tool surface is complete. The server runs real headless Grok agents in the

foreground or detached in the background, streams progress while they run, stops a run on request,

reviews git diffs, researches questions on the web, lists the sessions those runs created, and

reports session, usage, and cost. See CHANGELOG.md for what shipped and

ROADMAP.md for what was considered and rejected.

Progress

A long agent run is visible while it happens, rather than a silent wait ending in a wall of text. When your client sends a progressToken, the server runs Grok with --output-format streaming-json and forwards a notification per event:

#5  list_dir .
#6  read_file README.md
#7  read_file — completed
#8  thinking: the user asked me to list files, read README.md, then …
#10 writing: DONE
#11 finished: end_turn (2 turns)

Progress tracks what the agent is doing, not what phase it is in. Reasoning and response text are coalesced so a token stream does not flood your client, while tool calls are reported as they happen. Clients that support resetTimeoutOnProgress will not time out mid-run.

A client that sends no progressToken gets the cheaper non-streaming path and pays nothing for this.

Requirements

  • Grok Build CLI 1.0.0 or newer, authenticated (grok models should succeed)
  • Node.js 22 or newer

If grok is not on your PATH, set GROK_BINARY to its full path when you register the server.

Install

Claude Code

claude mcp add grok-build -s user -- npx -y grok-build-mcp-server

-s user registers the server for your whole account rather than for the directory you happen to be in. Without it the scope is that one project, which is rarely what you want for a general coding assistant, and the symptom is a server that is missing the next time you start Claude Code somewhere else.

Then, in Claude Code:
