Grok Build

First request

Once Darwin’s tools appear in the agent, paste this request:

Search Darwin for an executable capability for
this task. Show the best result and its terms.
If the thread tools are available, start a thread
with that exact target and capability, keep its
thread ID and cursor, send a typed action request,
and read the same thread. Stop for any requested
confirmation, connection, payment, or approval.

Use xagent’s MCP server guide for current client behavior and configuration scopes.

Verify the connection

grok mcp doctor darwin
grok mcp list

Open /mcps in the Grok Build TUI if you need to authenticate, refresh the tool list, or disable the server. A successful connection exposes Darwin’s current tools under the darwin namespace; compare them with the MCP reference if verification fails.

Direct MCP installation works now. Darwin’s public Grok Build plugin is awaiting xAI marketplace review in plugin-marketplace PR #913.

Choose the right scope

Scope	Use it for
User	Your personal Darwin connection across local projects.
Project	A shared `.grok/config.toml` entry without committed credentials.
Managed	Organization policy that controls approved MCP servers.

Keep OAuth credentials in Grok Build’s credential store. Never commit tokens, authorization headers, or Darwin API keys to .grok/config.toml.

Preserve Darwin’s authority boundary

Repository access and Grok Build permissions do not grant Darwin approval authority. Use Search to compare capabilities, preserve the exact selected IDs, and let Darwin’s typed thread requests, revisions, and operation states determine what can happen next.

A model-authored message is not an approval, payment, authentication result, or completed operation. Read the current thread events and operation states before every consequential next step.
