Verdicts
Resy
Resy is American Express's diner reservation network, now including Tock's venues, with venue plans priced from $289 a month and a public status page. Outside agents have no public API or MCP server. Resy reaches assistants through its own apps in Claude and ChatGPT and an Amex-hosted MCP endpoint that accepts only pre-registered clients.
Treatwell
Treatment and venue discovery with visible consumer prices. Open agent booking access was not verified.
Before you call either
Resy
- Don't plan to call Resy from another agent. Hand the booking to the person in the Resy app, or in Resy's app inside Claude or ChatGPT
- Do not automate the Resy website or app, since Resy runs a bot-detection programme against automated booking
- Don't give a Resy password to an unofficial server such as io.github.chrischall/resy-mcp. It isn't Resy's and asks for the account email and password
- Check status.resy.com before a booking run. The 7 October maintenance took app login, search and booking offline for two hours
Treatwell
- Hand the final booking to the person unless Treatwell has approved an integration.
- Check the selected venue’s cancellation deadline and payment option.
