# Fit Rocket

> A free personal weight-loss PWA. You log calories in and out plus daily weigh-ins; it projects an honest goal date from your real pace and audits your logs against the scale — when the two progress bars move together, your tracking is honest. AI counts meal photos. It's also an MCP server, so an AI agent can read your live numbers or log for you with a key you mint and revoke.

No ads, no third-party trackers, free. Sign in with Google.

You can try it without an account: the interactive sample journey at https://fitrocket.in/ ("See it working first") runs the real dashboard on six weeks of sample data, nothing saved.

## Connect an agent (MCP)

Point any MCP-speaking agent at `https://fit-rocket-proxy.usman-hafiz-awan1.workers.dev/mcp` with an agent key as a Bearer header. Keys are minted in Settings → Connected agents (read only or read & write, shown once, revocable) — you need a free account first. A connected agent can read the user's dashboard numbers and, with write access, log meals, weigh-ins, and workouts or start a new phase — every operation passes through the same security rules as the app itself. The full setup guide lives at https://fitrocket.in/connect.md (and https://fitrocket.in/connect/); the machine descriptor at https://fitrocket.in/.well-known/mcp.json.
