HealthKit-MCP

Read-only Apple Health context for MCP-capable agents.

A bridge that syncs Apple Health aggregates from an iPhone app into a scoped backend and exposes sleep, workouts, training load, and trends through a read-only Model Context Protocol server.

Not released yet. The build is private for now.

Platform: MCP / iOS / Supabase
Availability: coming soon

Problem

Apple Health has rich personal context, but there is no normal server API an agent can read from safely.

What I built

A TypeScript MCP server, Supabase schema, and iOS HealthKit sync plan that move aggregate summaries instead of raw health samples.

Highlights

Read-only MCP tools for daily summaries, sleep, workouts, training load, and trends.
Demo mode runs without a backend; the Supabase path is prepared for real user isolation.
The iPhone side reads HealthKit locally and syncs aggregates instead of raw samples.
Built for ChatGPT, Claude, Codex, and Claude Code as MCP-capable clients.
