Old script used deprecated Health.read() with Health.Types.* and .quantity
— every read silently failed in try/catch, so no samples were ever collected.
Rewrote to use Health.queryQuantitySamples() with string type identifiers
and .quantityValue(unit) per current Scripting app docs. Added proper units
(kg, mmHg, count/min, count, percent) for each metric type.
Also adds /scriptable/health-sync.js endpoint to serve the script directly.
- Add vitals table (type, timestamp_utc, value JSON, source) with UNIQUE
(type,timestamp_utc) for idempotent upserts.
- POST /ingest: Bearer-protected HTTP endpoint accepting batched health
samples (weight, blood_pressure, heart_rate, spo2, steps, sleep, ...).
Weight samples are mirrored into weight_log so existing weight tools see them.
- recent_vitals MCP tool: reads back ingested vitals, grouped by type with
min/avg/max/units over a configurable window.
- 6 new tests (31 integration + 2 unit total, all passing).
- Verify live: /ingest POST -> recent_vitals round-trip over MCP protocol.
Parameter-less tools in rmcp generated inputSchema: {} (empty dict
with no type field), which the Hermes MCP client rejects — one bad
tool fails the entire tools/list response.
Fix: added NoParams struct (empty, derives JsonSchema) and changed
get_goals to accept Parameters<NoParams>. schemars generates
{"type": "object", ...} for empty structs, which is valid.
- Search URL: search.openfoodfacts.org/search (not /api/v1/search)
- Search-a-licious returns no nutriments in hits — fetch each via v3 API
- Fall back to nutriments_estimated when no_nutrition_data is set
or nutriments object has <3 keys (common for fresh produce)
- Handle brands as array or string from search API
- systemd user service deployed on Pi5 (port 9432, API key auth)
- Registered with Hermes via mcp_servers config
- Hermes skill at ~/.hermes/skills/productivity/nutrition-tracker/
- Git remote: git.darkmark.co.uk/amerlo/nutrition-mcp
