MyFitnessPal — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the myfitnesspal-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install myfitnesspal --cli-only
   

2. Verify: myfitnesspal-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer):

go install github.com/mvanhorn/printing-press-library/library/productivity/myfitnesspal/cmd/myfitnesspal-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

When to Use This CLI

Reach for this CLI when an agent needs to reason over a user's actual eating, exercise, or weight history — especially across windows longer than today. The local SQLite store + agent-shaped context command means one tool call replaces the back-and-forth of pasting yesterday's diary into the chat. Use it for nutrition coaching, deficit calibration, macro analysis, recall questions ('every time I logged X'), and anywhere the official MFP UI's per-meal rollup blocks the question.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Local state that compounds

• export csv — Export your food diary to CSV with one row per logged food, not per meal. Premium MFP only ships per-meal CSVs.

  Reach for this when an agent needs the user's full eating history at food granularity for analysis, training, or long-form coaching memory.

  myfitnesspal-pp-cli export csv --from 2026-01-01 --to 2026-05-08 --out diary.csv
  

• analytics top-foods — Pareto query: which N foods drove X% of your protein/carbs/fat/fiber/sugar/calories over a window?

  Use when an agent is helping the user understand what's actually driving a macro target, not what they think is.

  myfitnesspal-pp-cli analytics top-foods --nutrient protein --days 60 --cumulative-percent 80 --json
  

• find — Full-text search across every diary entry and food in the local store. Returns date, meal, servings, calories per match.

  Use when an agent needs to recall every time the user logged a specific food without scrolling through months of diary.

  myfitnesspal-pp-cli find --food "Chipotle Bowl" --from 2026-01-01 --json
  

• analytics streak — Longest run of consecutive days where calorie totals fall within ±tolerance of your goal.

  Use when the user asks how their adherence is trending — answer arrives without subjective interpretation.

  myfitnesspal-pp-cli analytics streak --days 60 --tolerance 0.05 --json
  

Agent-native plumbing

• context — Single-call snapshot of the last N days: diary totals, weight trend, current goals, recent foods, macro deltas — sized for an agent context window.

  First call any agent should make before reasoning about a user's nutrition — gives the full picture in one shot.

  myfitnesspal-pp-cli context --days 14 --json

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

myfitnesspal-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Build agent context for a coaching question

myfitnesspal-pp-cli context --days 30 --json --select diary_totals,weight_trend,goals

One tool call gives the agent everything it needs to answer 'should I cut more this week?' without back-and-forth pasting.

Find every time you logged a food

myfitnesspal-pp-cli find --food "Greek yogurt" --from 2026-01-01 --json --select date,meal,servings,calories

Local FTS over your synced diary; instant answer to recall questions the MFP web UI requires scrolling for.

Per-food CSV for a quarter

myfitnesspal-pp-cli export csv --from 2026-01-01 --to 2026-03-31 --out q1-2026.csv

One row per food entry with full nutrients — the export premium MFP doesn't deliver.

Top foods driving a macro

myfitnesspal-pp-cli analytics top-foods --nutrient protein --days 60 --cumulative-percent 0.8 --json

Pareto query over the local diary: which foods drove most of your protein over the last 60 days.

Adherence streak

myfitnesspal-pp-cli analytics streak --days 60 --tolerance 0.05 --json

Longest run of days inside ±5% of your calorie goal. Goal value is read from the most recent goal_snapshot synced into the local store; pass --goal-calories <value> to override.

Auth Setup

MyFitnessPal closed their public API. This CLI uses your logged-in browser session — log in to myfitnesspal.com in Chrome, then run myfitnesspal-pp-cli auth login --chrome. Cookies are read from the .myfitnesspal.com domain. Sessions usually last 7-30 days; when they expire, log in again in Chrome and re-run auth login --chrome.

Run myfitnesspal-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  myfitnesspal-pp-cli api-user --user-id 550e8400-e29b-41d4-a716-446655440000 --agent --select id,name,status
  

• Previewable — --dry-run shows the request without sending

• Offline-friendly — sync/search commands can use the local SQLite store when available

• Non-interactive — never prompts, every input is a flag

• Explicit retries — use --idempotent only when an already-existing create should count as success

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

myfitnesspal-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
myfitnesspal-pp-cli feedback --stdin < notes.txt
myfitnesspal-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.myfitnesspal-pp-cli/feedback.jsonl. They are never POSTed unless MYFITNESSPAL_FEEDBACK_ENDPOINT is set AND either --send is passed or MYFITNESSPAL_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

myfitnesspal-pp-cli profile save briefing --json
myfitnesspal-pp-cli --profile briefing api-user --user-id 550e8400-e29b-41d4-a716-446655440000
myfitnesspal-pp-cli profile list --json
myfitnesspal-pp-cli profile show briefing
myfitnesspal-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
