What Wetware does

Wetware is a remote MCP server that gives an AI assistant the numeric machinery for nutrition and training: exact TDEE math, a deterministic meal-plan solver, a food diary measured in grams, and a workout log. It handles four groups of work.

Targets & profile

Calorie and macro targets computed from body stats, goal, and activity level — recalculated whenever the profile changes.

Weekly plan & groceries

A 7-day, 3-meal-a-day plan built from a curated recipe catalog, plus one aggregated grocery list covering all 21 meals.

Food diary

What was actually eaten, logged by the gram, checked against the day’s calorie and macro target.

Workout log & food repository

Every saved body-weight change plus training sessions and lift sets, tagged and totaled by week, with user-set training goals and all-time trends — alongside a shared, user-built repository of product macros anyone can search and contribute to.

A few additional tools power the interactive panels’ internal UI only (for example, fetching swap candidates for the plan board) and aren’t meant to be called directly.

Example prompts

Say what you want in your own words. A few starting points:

Set up targets

“I’m a 30-year-old man, 84 kg, 181 cm, moderately active. I want to get to 78 kg in 12 weeks.”

Computes and saves your daily calorie and macro targets

Plan the week

“Plan next week and turn it into one grocery list.”

Generates the 7×3 plan, then the aggregated list

Log a meal

“For lunch I had 200 g grilled chicken and a small side salad — how much room do I have left today?”

Logs the meal, then reports remaining calories and macros

Log a workout

“Boxing for 90 minutes. Then bench: 100 kg for 10, 90 kg for 10. How am I tracking against my goals this week?”

Logs the timed activity and each lift set, then shows weekly totals and goal progress

Swap a meal

“I’m lactose intolerant — swap out tomorrow’s dinner for something dairy-free.”

Replaces the meal with a compliant, rebalanced alternative

Interactive panels

On hosts that support MCP Apps, five entry points open a visual panel instead of a chat reply. Every capability is also reachable through the tools above, so hosts without Apps support lose nothing.

get_started
First-run onboarding: guides a new user through profile, preferences, and their first plan in one panel.
daily_dashboard
The Today panel: calorie-budget ring, one-tap meal logging, and the day’s eaten and trained log, plus a separate full-page Trends view with body weight over time, per-exercise charts, and training-goal progress.
meal_plan_board
The weekly 7×3 grid: calories vs. target per day, weekly macro split, cook times, plan history, one-tap “Ate it” logging, and clickable recipes with full ingredients and steps.
grocery_checklist
A tick-off shopping checklist for the active plan’s aggregated ingredients.
profile_studio
A what-if targets calculator, plus the profile and preferences editor.

Limitations & troubleshooting

Calorie band

Every day in a generated plan lands within ±5% of your calorie target, not exactly on it — a fixed recipe catalog can’t hit every day precisely and still vary the food.

Infeasible plans

If your allergies and dislikes leave too few compliant recipes (heavy combinations, like lactose and gluten together, are the usual cause), plan generation names the blocking constraints instead of returning a partial plan. Relax one and try again.

Allergens

Five allergens — lactose, gluten, nuts, seafood, eggs — are hard-excluded from every plan. Anything else you report is a soft dislike: Wetware can’t guarantee it’s absent, so check ingredients yourself for allergies outside this list.

UTC days

The diary and workout log key on UTC calendar days, not your local time. Logging just after local midnight west of UTC can land on what looks like “yesterday” — say the date explicitly if it matters.

Training calories

Wetware records every successful profile-weight change and logs sports, gym sets, weekly totals, training goals, and all-time Trends. It does not yet estimate calories burned from training or adjust your nutrition budget from logged workouts.
