Connect ChatGPT
Prerequisites
Section titled “Prerequisites”- A ChatGPT plan that allows adding custom MCP connectors
- An UptimeMonitoring account — sign in at app.uptimemonitoring.com
Connect
Section titled “Connect”UptimeMonitoring is listed on the ChatGPT app store — search for it in ChatGPT’s connector picker, or install manually:
- In ChatGPT, open Settings → Connectors.
- Add a custom connector and enter the remote MCP URL:
https://api.uptimemonitoring.com/mcp- Complete the OAuth flow when ChatGPT prompts you to connect your UptimeMonitoring account.
ChatGPT uses OAuth exclusively for custom connectors — you cannot pass a custom Authorization header via the connector UI. If you need API-key access from a backend agent, use the OpenAI API path instead.
If you need full MCP tool access while testing prerelease tool changes, enable Developer Mode in ChatGPT before adding the connector.
Verify
Section titled “Verify”In a new ChatGPT chat with the connector enabled, ask:
list my monitors
You should see the connector invoked and a list returned.
