**Am I recovered? Did my fueling work? What should change next week?**
The only MCP combining MacroFactor nutrition with Garmin training data.
MacroFactor MCP is a local Fueling & Recovery Decision Engine. Give your MCP
client a MacroFactor export, optionally add Garmin, and ask for a decision
instead of manually comparing nutrition, sleep, body, and training screens.
## Quickstart
Install [`uv`](https://docs.astral.sh/uv/), then confirm the packaged server starts:
```bash
uvx macrofactor-mcp
```
Export your data from MacroFactor, put the `.xlsx` file in one local directory,
and add this to your MCP client configuration. Use absolute paths.
```json
{
"mcpServers": {
"macrofactor": {
"command": "uvx",
"args": ["macrofactor-mcp"],
"env": {
"MACROFACTOR_DATA_DIR": "/absolute/path/to/macrofactor-exports",
"MACROFACTOR_DB_PATH": "/absolute/path/to/macrofactor.duckdb"
}
}
}
}
```
Restart the MCP client. The server imports new workbooks on startup. Run
`setup_check`, then ask one of the questions below. If a desktop client cannot
find `uvx`, replace `"uvx"` with the absolute path returned by `which uvx`.
## Four flagship workflows
All examples below use synthetic data.
### `recovery_check` — Am I recovered?
Combines last night's sleep, HRV, body battery, training load, and yesterday's
fueling into a readiness view.
```text
Recovery Check: 2026-07-08
Sleep: 7h 38m, score 82; HRV +4 vs 7-day average
Training load: ACWR 1.08 (optimal)
Yesterday: 96% calorie target; 101% protein target
Overall: All systems go — 4 positive signals.
```
### `daily_briefing` — What do today's signals say together?
Shows the day as one picture instead of separate nutrition and training logs.
```text
Daily Briefing: 2026-07-08
Intake: 2,340 kcal (P 171g / F 72g / C 248g)
Adherence: 98% calories | 101% protein
Body Battery: 28 → 83 | Sleep: 7h 38m, score 82
Training: Productive | Load 612/568 (ACWR 1.08)
```
### `weekly_report` — What should change next week?
Reviews seven days of nutrition, weight, workouts, sleep, and training load.
```text
Weekly Report: 2026-07-02 to 2026-07-08
Average: 2,315 kcal | 168g protein
On target: calories 6/7 days | protein 7/7 days
Training: 4 sessions | Sleep: 7h 26m average
Next-week signal: fueling was consistent; protect sleep before adding load.
```
### `nutrition_performance_correlation` — Did my fueling work?
Compares nutrition with next-day Garmin recovery signals. It reports sample
sizes so small or missing datasets stay visible.
```text
Nutrition → Performance Correlation: 28 paired days
Protein >=90% target: next-day HRV 51 vs 45 (+6)
Protein >=90% target: sleep score 81 vs 76 (+5)
Energy deficit days: body battery 68 vs 75 (-7)
Observation: higher-protein days tended to precede better recovery.
```
## MacroFactor-only or MacroFactor + Garmin
| Mode | Decisions available |
|---|---|
| MacroFactor only | Nutrition, weight, workouts, `daily_briefing`, and `weekly_report`. Recovery output uses the nutrition signals that exist. |
| MacroFactor + Garmin | All four flagship workflows, including sleep, HRV, body battery, activities, and training load. |
Garmin is optional. To enable it, point `GARMINTOKENS` at an existing local
Garth/Garmin token directory, then run `sync_garmin`.
## Platform support
- macOS and Linux
- Windows is untested
- Python 3.10 or newer
## Limitations
- v0.1 requires a manual MacroFactor export; it does not connect to a MacroFactor API.
- Garmin correlation workflows need overlapping MacroFactor and Garmin dates.
- Correlations are observational, not proof that one behavior caused another outcome.
- Import support follows the current MacroFactor Quick Export and All-Time Data workbook layouts.
## Privacy
Raw nutrition, body, workout, and Garmin data stays in the local DuckDB
database. The server does not upload that database. However, **MCP tool results
are sent to whatever model or client the server is connected to**. Review that
client's data policy and avoid requesting more detail than you want to share.
