The full story
Whoop's official API offers 13 read-only endpoints, while its app shows far more. The maker reverse engineered the private API the iOS app uses and wrapped it as an MCP server, so Claude or any MCP-capable assistant can query and act on the whole account in plain English.
It exposes 48 tools across 47 of Whoop's services: recovery details such as HRV, resting heart rate and skin temperature, minute-by-minute sleep stages, strain, heart-rate zones, VO2 max, the full strength-training history and the behaviour journal. It is free and open source.
