You: "Look up all customers in California"

GPT: *uses your MCP server's query_customers tool*
     Found 42 customers in California:
     - Acme Corp (Los Angeles)
     - TechStart (San Francisco)
     ...

You: "Create a $25K deal for Acme Corp"

GPT: *uses create_deal tool*
     Deal created:
     - Customer: Acme Corp
     - Amount: $25,000
     - Deal ID: DEAL-789

GPT: *uses send_email tool*
     Email sent to contact@acmecorp.com

Best Practices

  1. Name servers clearly - Use descriptive names in config
  2. Monitor usage - Check Dashboard -> MCP Servers -> Logs

​
Troubleshooting

Verify your MCP URL is correct and accessible. Test it directly in your browser.
Ensure the API key in GPT Actions matches what’s configured in your MCP server settings.
Optimize your MCP server to respond quickly. ChatGPT actions have strict timeout limits.
