• Registry nameio.bodywise/mcpverified in the MCP registry

The registry name sits under bodywise.io. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-20 the server answered initialize and tools/list without a sign-in. First answer in 202 ms.

• Its tools do every use case we checked: Calculate calorie and macro targets for bulking; Work out daily protein grams per kilogram.
• Checked on 2 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

• Every tool passes all six checks.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• maintenance_calories

  Estimate daily maintenance calories (Mifflin-St Jeor × activity multiplier) for an adult.

• bulking_calories

  Maintenance calories plus the 10–15% lean-gain starting surplus and a weekly gain guide (the Bodywise bulking calorie calculator).

• calorie_calculator

  Older calculator kept for backwards compatibility: maintenance (Mifflin-St Jeor × named activity level) times 0.80, 0.85, 1.00 or 1.10 by goal. It has no Bodywise page. For the bulking calorie calculator page (+10–15% range) call…

• daily_protein_range

  Daily protein of 1.6–2.2 g per kg bodyweight and the per-meal split (the public Bodywise protein calculator page, /hub/protein-calculator). Prefer this over protein_calculator when matching the website.

• protein_calculator

  Older goal-based daily protein range (fat_loss, hypertrophy, maintenance, endurance; optional lean mass), kept for backwards compatibility. It has no Bodywise page and can give different figures from the public protein calculator — for…

• macro_calculator

  The public Bodywise macro calculator page (/macro-calculator): maintenance calories (Mifflin-St Jeor × activity multiplier), a goal target (build +300 kcal, maintain 0, lean −400; never below 1,200 kcal) and daily protein, fat and carb…

• protein_distribution_calculator

  Split a daily protein target across meals and compare each meal with 0.4 g per kg of bodyweight.

• one_rep_max

  Estimate a 1RM (Epley, counting reps in reserve) and working weights from a completed set.

• rpe_rir_calculator

  Working weight for a target number of reps at a target RPE or reps in reserve (Epley model).

• fat_free_mass_index

  Calculate fat-free mass, FFMI and height-normalised FFMI (Kouri et al., 1995).

• fat_loss_timeline_calculator

  Projected weeks and daily deficit to reach a target body-fat percentage, assuming all loss is fat (~7,700 kcal/kg).

• lift_balance_calculator

  Squat, deadlift and overhead press as percentages of bench press. Descriptive only.

• dots_wilks_calculator

  DOTS (IPF 2019) and original Wilks scores for a powerlifting total at a given bodyweight.

• creatine_dosing_calculator

  Creatine monohydrate maintenance (3–5 g/day) and optional loading dose (~0.3 g/kg/day for 5–7 days).

• ipf_gl_points_calculator

  IPF GL points (IPF 2020 classic three-lift coefficients) for a squat + bench + deadlift total at a given bodyweight.

• strength_to_bodyweight_calculator

  Each lift as a plain multiple of bodyweight. Descriptive only; it never labels a lifter's level.

• barbell_warm_up_calculator

  Warm-up sets at about 40, 55, 70 and 85% of a working weight, then the working weight, with plates per side (plates 25–1.25 kg).

• lean_bulking_rate_calculator

  Weekly and monthly weight gain at 0.25–0.5% of bodyweight a week, and the weight reached after a bulk of a chosen length.

• double_progression_calculator

  Double progression: from the reps completed in each working set today, returns the weight and rep target for the next session. Weight only goes up once every set reaches the top of the rep range.

• dumbbell_barbell_converter

  Converts dumbbell and barbell loads. The total is arithmetic for any lift. A ranged strength estimate is returned for the flat bench press only, from one small unpublished study (dumbbell 1RM about 80% of barbell 1RM); for other lifts the…

• weekly_volume_auditor

  Describes weekly hard sets per muscle group against the roughly 10-or-more weekly sets the 2026 ACSM position stand favoured. Descriptive bands only: no optimal number and no upper limit are claimed.

• rest_between_sets_calculator

  A rest window in seconds for an exercise type and goal, with the evidence caveats. Not a proven optimum.

• bulking_stall_calculator

  Compares weekly weight change with a 0.25-0.5% of bodyweight a week monitoring range and suggests a calorie step. Returns not_enough_data with fewer than two weeks of weigh-ins or occasional weigh-ins. Never diagnoses a medical cause.

• fat_calculator

  Daily fat: 0.8 g per kg bodyweight by default (allowed 0.5–1.2 g/kg). Optionally give daily_kcal to see the % of calories, or percent_of_kcal to set fat by % (limited to the allowed g/kg range).

• carbohydrate_calculator

  Carbohydrate grams = (daily kcal − protein g × 4 − fat g × 9) ÷ 4, with an optional training-day / rest-day split that keeps the weekly average.

• macro_meal_plan

  Use this first when asked for a meal plan. Returns daily calories, protein (1.9 g/kg default), fat (0.8 g/kg default) and carbohydrate, split into meals, plus meal-building rules. Get daily_kcal from maintenance_calories, bulking_calories…

• get_exercise
