Developer & tester guide

Test the HereKey MCP connection

Use a separate preview connection to try updates in your own ChatGPT account. For normal installation, follow the HereKey for ChatGPT guide.

Connection settings

Name: HereKey Concierge Preview
Preview MCP URL: https://herekey.app/concierge-preview/mcp
Authentication: OAuth

Connect and test

In ChatGPT on the web, open Plugins. Choose the plus button, then Add custom MCP server, if your account or workspace allows it.
Enter the preview name and URL above, select OAuth, review the connection notice, and create the connection.
Choose Continue with HereKey. Approve in your own HereKey app, then return to the original browser page to finish connecting.
Start a new conversation and select HereKey Concierge Preview. Try: “How much would it cost to fix a leaking kitchen faucet at home? Don’t send a request yet.”

The preview uses the live service API. Sending a request can create a real quote and notification. Use your own account and contact details, and do not approve or pay unless you intend to book the service.

Useful checks

Try your saved home address, a fresh app location, and a different supplied address.
For a linked account, the concierge should not need your phone number to deliver the request.
If you approve in HereKey, return to the original connection page. For an expired link, start a fresh connection in ChatGPT.
Start a new conversation after an update. Refresh the connection’s tools when tool definitions change; reconnect only if prompted or when testing authorization.

Testing the production endpoint instead

Use a clearly named separate connection with OAuth and https://herekey.app/mcp. Production and preview run separate releases and maintain separate connections. Do not switch your normal connection just to test a preview.

You do not need a business API key, secret, member ID, or token. Never paste credentials into a conversation. Keep ChatGPT permission prompts enabled. Official OpenAI MCP setup instructions.
