Syncky: open protocol, reference agent and reference server
Syncky Health sends the Apple Health data you choose from your iPhone to your own AI agent (local MCP server) or your own server. The AI agent route is end-to-end encrypted. Your agent and your server can both write entries back into Health once you allow writing on the iPhone.
Client health-data envelopes are end-to-end encrypted (HPKE Auth + ChaCha20-Poly1305): the relay sees delivery metadata and emits plaintext hub notices, but sees no health values. The app can also send straight to a server the user runs, with no relay at all. The user's agent or server receives plaintext, and a chosen model sees what the agent supplies.
Get Syncky Health on the App Store or visit syncky.app.
Install for an MCP client
Requires Node.js ≥22.15 and npm. The npm package embeds its runtime packages and has no runtime dependencies. Start the local stdio server with:
npx -y @syncky/agent mcp
For a client whose JSON configuration uses mcpServers:
{"mcpServers":{"syncky":{"command":"npx","args":["-y","@syncky/agent","mcp"]}}}
