Why companies add ToolRouter to Grok
Companies that already run Grok still need a specialist catalog the rest of the company can share with Claude and ChatGPT. Without that, Grok grows its own tool stack and its own invoices. ToolRouter is one Grok connector for that catalog, with seats and an audit log (Business and above).
Grok’s built-in connectors stay. ToolRouter sits beside them.
