Fever × 42a · Experience concierge

Fever’s plans, inside ChatGPT and Claude

One MCP server over Fever’s own data: 1,394 plans (every one Fever lists in London, 1,129, and the most-rated 265 in New York) with venues, prices, booking fees, ratings where Fever shows them, and Fever’s own FAQs. Sessions, ticket prices and tickets left are read live from feverup.com when a person asks. Every booking ends in a handoff to Fever’s own plan page with the date and ticket selected: the concierge never buys, holds or charges anything, and Fever’s house rules (fees always shown, no resale links, no invented codes) apply on every answer.
