Fitness content is a place where a confident wrong answer has physical consequences — invented movements, wrong muscle groups, unsafe cues. This puts a structured library behind the agent so the exercises it names, and the muscles it attributes to them, come from the source.
The official MCP server for exerciseapi.dev, a curated exercise library spanning strength, calisthenics, yoga, pilates, mobility, physical therapy, plyometrics and stretching.
- Search across the library with filtering handled server-side, so the shortlist comes back already narrowed
- The full record for one exercise: instructions, form tips and safety notes written by people rather than generated
- Primary and secondary muscles named specifically, not as "chest" or "legs"
- Browsable lists of categories, equipment and muscles, so an app's filter UI can be built from the real vocabulary
- Library statistics, and demonstration videos for a growing subset of exercises
