Restart Claude Desktop

Close and reopen Claude Desktop to load the CATO MCP server.

​
Verify Installation

Once Claude Desktop restarts, try asking: 
"What tools are available in CATO?"

"Check portfolio for 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb0"

"Find best yield for USDC on Cronos"
If CATO is properly configured, Claude will use the MCP tools to answer these queries.
