Environment / auth
  • 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.
