Connect ChatGPT

ChatGPT supports remote MCP servers via custom connectors (currently rolling out to ChatGPT Pro / Team / Enterprise).

Steps

1. Open Settings → Connectors → Custom connectors in ChatGPT.
2. Click Add custom connector.
3. Configure the connector:
   • Name: Picnic
   • Server URL: https://agents.usepicnic.com/mcp
   • Authentication: OAuth (auto-detected from the server's metadata)
4. Click Connect. ChatGPT will open Picnic's consent page in a new tab — sign in with your passkey and approve the scopes you want to grant.
5. Back in ChatGPT, the connector should show as Connected.

Try it out

Start a new chat with the Picnic connector enabled and try:

"Show me my last 10 transactions on Picnic."

ChatGPT will call get_transactions and walk you through the results.

Notes

• ChatGPT's custom connector UI changes occasionally. If the wording is different, look for "MCP server", "Add connector", or "Custom integration" — it's all the same flow.
• Custom connectors require admin approval in some plans. If the option is missing for you, ask whoever manages your ChatGPT workspace.
