# TrackPep

> TrackPep (trackpep.com) is a privacy-first peptide and GLP-1 tracking app for iOS, Android, and web. It is a record-keeping and education tool: users log doses, convert a prescribed dose into syringe units with built-in calculators, set their own reminders, and track weight, hydration, and side effects alongside their protocol. TrackPep does not provide medical advice and never recommends or suggests a dose.

## Agent access (MCP)

Connection instructions for Codex and browser agents: https://www.trackpep.com/agents.

TrackPep runs two Model Context Protocol servers over streamable HTTP. A machine-readable index is at https://www.trackpep.com/.well-known/mcp.json.

### Public server — no account needed

https://www.trackpep.com/api/mcp/mcp

- `search_compounds` — Search TrackPep's public compound reference by name or alias. Returns names, slugs, categories and the evidence status we publish for each entry. Reference information only — it contains no dosing instructions.
- `get_compound` — Fetch one compound reference page by slug: what it is, its published half-life, storage and reconstitution notes, and our citations. Educational reference only; it does not contain or recommend a dose.
- `glossary_lookup` — Look up a plain-language definition from TrackPep's peptide and GLP-1 glossary. Matches on the term or any part of it, and returns the definition plus related terms.
- `syringe_units_for_prescribed_dose` — Unit conversion for a reconstituted vial. Given the vial strength, the bacteriostatic water added, and a dose amount the caller already has, returns the equivalent volume in millilitres and the reading on a U-100 or U-40 insulin syringe. It converts the numbers it is given; it does not choose, recommend, or check the appropriateness of a dose.
- `reconstitution_concentration` — Given a vial strength in milligrams and a volume of bacteriostatic water in millilitres, returns the resulting concentration in mg/mL and how much of the compound is in one syringe unit. Pure arithmetic; it does not suggest how much water to use or what to draw.
- `list_guides` — List TrackPep's published guides — titles, descriptions, the short extractable answer where one exists, and URLs. Optionally filtered by a search term.

### User server — the signed-in person's own log

https://www.trackpep.com/api/mcp/user/mcp

Not yet accepting connections — its authorization server is not enabled. https://www.trackpep.com/.well-known/oauth-protected-resource returns 503 with that reason until it is.

- `get_today` (scope `read`) — Read the signed-in TrackPep user's own log for today in their local timezone: doses recorded, meals with calorie and protein totals, workouts, habit check-ins, water, and their latest weight. Read-only.
- `get_progress` (scope `read`) — Read the signed-in TrackPep user's own trends over a window of days: weight entries, training volume and session count, average daily calories and protein, and how many doses they recorded. Read-only.
- `log_meal` (scope `write:log`) — Record a meal in the signed-in user's food log. Supply either per-item foods with their grams and per-100 g nutrition (totals are then computed by TrackPep from those items) or the meal's totals directly. Writes only; it does not judge or advise on what was eaten.
- `log_dose` (scope `write:log`) — Record, in the signed-in user's log, a dose amount that the user has supplied. The amount and its unit are required and are stored exactly as given: TrackPep does not calculate, convert, infer, default, or suggest a dose, and this tool refuses any call that does not carry an amount. Ask the user for the amount; never supply one on their behalf.
- `log_workout` (scope `write:log`) — Record a completed workout session and its sets in the signed-in user's training log. Volume, set count and duration are computed by TrackPep from the sets; send the sets and when the session ended.
- `log_habit` (scope `write:log`) — Record a habit or wellness check-in in the signed-in user's tracker, for today or yesterday only. Idempotent: calling it twice for the same habit and day updates that day rather than adding a second entry. It cannot reach further back than yesterday, so it can correct today's entry but never rewrite the user's history.

An authorized agent can read the user's own doses, meals, workouts, habits, water and weight, and can add new entries of those kinds. It cannot read or write anyone else's data, cannot change account or billing settings, and cannot delete anything. `log_dose` records an amount the user supplies and refuses a call without one — TrackPep never determines a dose.

## What TrackPep does

- Dose logging with compound, amount, injection site, and notes.
- Reconstitution calculator: mg per vial + bacteriostatic water → the exact U-100/U-40 syringe reading for a dose the user enters.
- Reminders and protocol schedules that the user sets.
- Vial inventory with remaining-amount and low-stock tracking.
- "Medication level" estimates based on published compound half-lives.
- Injection-site history: the app shows which zones were logged recently so the user can rotate; it does not pick a site for them.
