Add ToolRouter to Grok at grok.com using a custom Bring Your Own MCP connector. Set up once and Grok can discover and call any tool in the catalog.
This guide is for the Grok connector (grok.com) path. Grok Bot is a separate downloadable xAI app with its own account-dependent setup path.
Step 1: Open Grok connectors
Go to grok.com/connectors.
Step 2: Add a custom connector
Click New Connector, then choose Custom (Bring Your Own MCP).
Fill in:
- Name:
ToolRouter - URL:
https://api.toolrouter.com/mcp
Save the connector. Grok can now reach the ToolRouter catalog when you attach it in a conversation.
No API key needed — your account is created automatically on first use.
Step 3: Use ToolRouter in a conversation
Start or open a Grok chat and attach the ToolRouter connector for that conversation. Ask Grok to do something that needs a tool — it will call the right skill from the catalog.
What can Grok do with ToolRouter?
Once the connector is attached, Grok can discover and use any tool in the catalog. Ask Grok to:
- Analyze a website's SEO
- Take a full-page screenshot
- Search the web for current information
- Generate images with 50+ AI models
- Look up domain information
- Check the weather
Grok will find and call the right tool automatically. There are 254 tools with 1,347 skills across 12 categories.
How do I add credits for paid tools?
Many tools are free. Free tools stay free — you only pay when a paid tool works. For paid tools, visit toolrouter.com/sign-up to claim your account and add credits. Failed paid calls don’t charge. Free tools never charge. Paid tools start at $0.005.
