Garmin Local MCP

What it does

Garmin Local MCP is a local-first data warehouse for Garmin Connect data. Unlike standard API wrappers, it syncs data into a local SQLite database and raw JSON snapshots, enabling complex longitudinal analysis (like sleep vs. training load correlations) without flooding the AI's context window with raw JSON payloads.

Tools

• query_metrics: Retrieve columnar time series for health metrics with aggregation.
• correlate: Calculate Pearson/Spearman correlations between two metrics with day-lag support.
• baselines: Compute personal mean and standard deviation bands for health metrics.
• anomalies: Detect outlier days and sustained streaks in wellness data.
• get_day: Get a merged view of wellness, sleep, and activity for a specific date.
• import_fit: Ingest manually exported Garmin wellness FIT bundles without authentication.
• sync: Fetch recent data from Garmin Connect into the local store.
