Health Data (your own Supabase)

CI npm MCP Registry

Your health data (weight, body composition, calories, macros, water) as an MCP data layer your AI can query. Zero custody: it lives in a Postgres database in a Supabase project you create and own — nobody but you ever holds your data or your keys. An iOS Shortcut syncs it daily from Apple Health; Claude (or any MCP client) reads it back through a connector that runs entirely inside your own project.

Apple Health --> "Sync Health Data" Shortcut --> your health-ingest function --> your Postgres
                                                                                      |
Claude  <-- run_readonly (SELECT-only) <-- your health-mcp connector function <------+

Nothing above touches infrastructure we operate. The two Edge Functions run on your Supabase project; the only thing that ever leaves your device is the Shortcut's HTTP POST straight to your own project's URL.

Pair it with fitness-tools

health-mcp answers "what happened" (your logged weight and calories); fitness-tools answers "so what" (TDEE, macros, body fat, 1RM). The get_energy_inputs tool returns {date, weight, kcal} entries shaped exactly for fitness-tools' adaptive-tdee — no reformatting needed. Ask Claude:

Get my energy inputs for the last 90 days, then compute my adaptive TDEE

adaptive-tdee needs at least 10 days that have BOTH a weigh-in and a calorie total — expect ~2 weeks of syncing before the pairing works.

with fitness-tools.

If you also train with Hevy, pair with hevy-mcp for the training side of the picture (routines, logged sets, 1RM trend).

Install

Three ways to get a working connector. All three end with the same thing: a Supabase project holding your two tables (daily_totals, measurements), two Edge Functions (health-mcp, health-ingest), and a connector URL you add to Claude.

1. Wizard (fastest — one command)

npx @almostjacked/health-mcp setup

Interactive: walks you through logging in to Supabase, picking or creating a project, applying the schema, deploying both functions, and minting your secrets — then prints the connector URL and Shortcut config.

Non-interactive (scripting / CI):

npx @almostjacked/health-mcp setup --new --name my-health --region us-east-1 [--org-index N]
# or, against a project you already have:
npx @almostjacked/health-mcp setup --existing <project-ref>

--region is required when running non-interactively (there's no TTY to prompt for it — the interactive wizard defaults the prompt to us-east-1). --org-index picks an organization by number when your account belongs to more than one; omit it if you only have one.

Requires Node >= 18 and a free Supabase account. Any step the wizard can't automate prints the exact manual fallback for that step (see path 2 below) and keeps going.

2. Manual dashboard (~15 min, no terminal)

Point-and-click through the Supabase dashboard yourself — no CLI, no Node. Full click-by-click instructions: docs/setup-manual.md.

Short version: create a project → SQL Editor, paste packages/core/setup.sql → Edge Functions, create health-mcp and health-ingest, pasting in the release bundles → Project Settings → Edge Functions, add MCP_TOKEN / INGEST_KEY secrets (any long random strings) → your connector URL is https://<project-ref>.supabase.co/functions/v1/health-mcp/<MCP_TOKEN>.

Supabase's free tier allows 2 active projects, so this fits alongside one other free project you may already have.

3. Claude Desktop

Download health-mcp.mcpb, double-click it, and paste in your Supabase project URL and secret key when prompted (from either install path above).

Prefer running it yourself instead of the .mcpb? It's a plain stdio server:

claude mcp add health-mcp -e SUPABASE_URL=<url> -e SUPABASE_SECRET_KEY=<key> -- npx -y @almostjacked/health-mcp

Sync your data: the Shortcut

An iOS Shortcut reads eight metrics out of Apple Health for the last 3 days and POSTs them to your health-ingest function daily. Generate, install, and automate it: docs/shortcut.md.

Don't use Shortcuts, or want to backfill older history? The ingest function accepts the same {"entries": [...]} payload from any HTTP client — script your own export against it. A dedicated browser-based export.zip importer/backfill tool is coming in 3c.

Tools

Tool	Description
get_schema	The Postgres schema (two tables) and the metric registry (names, units, classes). Call before writing SQL for the query tool.
get_sync_status	Latest date, row count, and days-since-last-entry per metric. Use to detect a stalled daily sync before trusting an analysis.
get_recent	Rows for the last N days (default 30), optionally one metric. Daily totals and individual measurements in one date-sorted list.
get_daily_summary	All metrics for one day (default: the most recent day with any data): totals plus every weigh-in/measurement.
get_stats	Min/max/avg plus a rolling-average series for one metric over a date range (daily/weekly/monthly rollup).
query	Escape hatch: run one read-only SQL statement (SELECT or WITH…SELECT) against the schema from get_schema. Writes/DDL rejected; LIMIT 500 enforced.
get_energy_inputs	Daily (date, weight, kcal) entries for days with both a calorie total and a weigh-in — shaped exactly for fitness-tools' adaptive-tdee.

Privacy Policy

Zero custody. health-mcp is software you run against infrastructure you own — we (the maintainers) never operate a server that sees your health data or your keys, and there is nothing to disconnect from us because nothing was ever connected to us.

• Your data lives only in the Supabase Postgres project you created. We have no access to it, no copy of it, and no way to see it.
• Your keys (MCP_TOKEN, INGEST_KEY, your Supabase secret key) are generated by you or the wizard running on your machine, stored as secrets in your own Supabase project, and — for the stdio/.mcpb install path — held locally by your MCP client (Claude Desktop / Claude Code) and sent only to your own project's URL.
• The Shortcut sends data straight from your phone to your Edge Function URL; it never passes through any server of ours.
• The query tool is SQL-guarded to read-only statements, and the database role it runs as (health_reader) is granted SELECT only — enforced at the Postgres level, not just in application code.
