Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`GROK_BINARY` Optional	Path to the grok executable. Only needed when grok is not on PATH.
`GROK_MCP_PERMISSION_CEILING` Optional	Highest permission level any call may request. Granted once at registration and never prompts again.
`GROK_MCP_DEFAULT_PERMISSION` Optional	Permission level used when a call specifies none. Must be at or below the ceiling.
`GROK_MCP_DEFAULT_MODEL` Optional	Model used when a call omits one.
`GROK_MCP_DEFAULT_EFFORT` Optional	Reasoning effort used when a call omits one.
`GROK_MCP_TIMEOUT_MS` Optional	Wall-clock kill for a single run, in milliseconds.
`GROK_MCP_STATE_DIR` Optional	Directory for background job records. Defaults to $XDG_STATE_HOME/grok-mcp.
`GROK_MCP_MAX_CONCURRENT_RUNS` Optional	Background runs alive at once. Use off, none, or unlimited for no cap.
`STRUCTURED_CONTENT_ENABLED` Optional	Emit structuredContent alongside _meta. Off by default because some clients mishandle it.
