Official public Model Context Protocol (MCP) server for Bodywise (bodywise.io).
Provides 35 deterministic fitness calculations, food data, and training guides: • Nutrition: TDEE maintenance, bulking surplus, macro splits, daily protein ranges, fat and carbohydrate targets, per-meal protein distribution (~0.4 g/kg). • Strength & Training: 1RM, RPE/RIR working weights, lift balance, barbell warmups, dumbbell-to-barbell conversions, weekly volume auditing, rest intervals. • Body Composition & Anal
Scored across 61 tools
Many tools are genuinely distinct, but there are several overlapping clusters around calories, protein and nutrition workflows (e.g. maintenance_calories, calorie_calculator, macro_calculator, bulking_calories; protein_calculator, daily_protein_range, protein_distribution_calculator). The descriptions often explicitly route the agent to the right tool, which prevents the set from being worse, but the boundaries are still easy to miss in a 61-tool surface.
All names use snake_case, which keeps them readable, but conventions are mixed: many end in _calculator, while others use verb_noun (get_exercise, search_foods, list_calculators), noun phrases (one_rep_max, muscle_map, workout_builder) or workflow/planner/simulator suffixes. The inconsistency is not chaotic, but it is not a predictable verb_noun pattern either.
With 61 tools, the server is far beyond a well-scoped set and contains obvious legacy/duplicate calculators kept for backwards compatibility. The domain is broad, but the count is still an extreme mismatch for an agent-facing tool surface.
Coverage is unusually broad: calories, macros, protein, body composition, lifting calculators, running fuelling, supplements, exercise/food lookup and public page access. There are minor gaps around longitudinal tracking/logging and some legacy duplication, but the core fitness-coach domain is well covered.
