GotCashback MCP server

Endpoint: https://mcp.gotcashback.com (streamable HTTP) · Docs: https://www.gotcashback.com/mcp-server/ · Registry name: com.gotcashback/gotcashback

GotCashback compares the cashback rates that multiple cashback portals currently pay for the same online or in-store retailer, and finds discounted gift cards from multiple sellers, across 30+ countries. Rates are refreshed several times a day. Every result carries the tracked GotCashback link for the portal; cashback is only credited when the purchase starts from that link.

All comparison tools work without an account. Signing in with a GotCashback account (OAuth 2.1, dynamic client registration, PKCE) unlocks the personal tools: profile, favorite stores, and cashback / gift card alerts.

This repository holds the public metadata for the hosted server (server.json for the Official MCP Registry). The server itself is closed-source and operated by GotCashback.
