# Grok Build

Run the Grok Build CLI as MCP tools: agent runs with live progress, code review, web research.

The current version, v0.2.4, was published to the official MCP registry on 2026-08-18. It is distributed as grok-build-mcp-server on npm, filed under Other by this index, and declares 9 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; [the index's current counts](/stats) put this record in context.

## Using Grok Build in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and **HOLDs the call** when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use **Install this server** for that).

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

```
uv tool install mcpindex-gate && mcpindex-config-wire
```

[method](/methodology)

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: [the eval, four-state verdict, honest limits](/methodology).

## That verdict was true at screening time (snapshot 2026-08-18).

Contracts can change after screening, with no version bump. The gate pins Grok Build’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

`GROK_BINARY`

Path to the grok executable. Only needed when grok is not on PATH.

`GROK_MCP_PERMISSION_CEILING`

Highest permission level any call may request. Granted once at registration and never prompts again.

`GROK_MCP_DEFAULT_PERMISSION`

Permission level used when a call specifies none. Must be at or below the ceiling.

`GROK_MCP_DEFAULT_MODEL`

Model used when a call omits one.

`GROK_MCP_DEFAULT_EFFORT`

Reasoning effort used when a call omits one.

`GROK_MCP_TIMEOUT_MS`

Wall-clock kill for a single run, in milliseconds.

`GROK_MCP_STATE_DIR`

Directory for background job records. Defaults to $XDG_STATE_HOME/grok-mcp.

`GROK_MCP_MAX_CONCURRENT_RUNS`

Background runs alive at once. Use off, none, or unlimited for no cap.

`STRUCTURED_CONTENT_ENABLED`

Emit structuredContent alongside _meta. Off by default because some clients mishandle it.
