Seatline and the true price of a ticket
An MCP server that compares live ticket inventory across marketplaces using the all-in price a buyer actually pays.
- For
- Agents and developers building ticket-price workflows
- Worth noticing
- Its comparison ranks marketplace listings by total buyer cost, not the advertised base price.
Field notes
Seatline describes an agent-facing workflow rather than a conventional consumer ticket marketplace. Its listed operations cover event resolution, event metadata, cross-marketplace price comparison, seat-level listing details, and standing watches for price or availability changes. The page says every tool is read-only and returns a marketplace link for checkout, while explicitly excluding ticket purchasing, inventory holds, and onsale automation. Its examples compare total fee loads on a $300 seat.
