## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 66/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS check failed: the endpoint is reachable over plaintext HTTP.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 545 tokens (~181/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## MCP tools (3)

### `warmup_calculator` (~164 tokens)

Calculate a barbell warmup ramp for any lift. Returns a structured set of warmup sets leading up to the work weight, with decreasing reps as weight increases. Based on standard barbell warmup methodology used in Starting Strength coaching. Powered by CoachSync.io.

Input parameters:

- `barWeight` (number): Bar weight. Defaults to 45 lb (20 kg). Use 35 for a women's bar, 15 for a training bar.
- `liftType` (string, required): The lift being warmed up for (e.g. squat, bench, press, deadlift)
- `roundingIncrement` (number): Round warmup weights to this increment. Default 5.
- `workWeight` (number, required): The target work set weight in pounds (or kg if unit is kg)

### `plate_loader` (~127 tokens)

Calculate which plates to load on each side of the barbell to reach a target weight. Supports custom bar weights and custom plate inventories for home gyms. Powered by CoachSync.io.

Input parameters:

- `availablePlates` (array): Optional list of available plate denominations. Defaults to standard plates [45, 25, 10, 5, 2.5].
- `barWeight` (number): Bar weight. Defaults to 45 lb.
- `targetWeight` (number, required): The total target barbell weight (bar + plates)
- `unit` (string): Weight unit. Defaults to lb.

### `novice_lp_generator` (~254 tokens)

Generate a structured 4-week novice linear progression program for a new or early-intermediate barbell trainee. Based on the Starting Strength model: squat every session, alternating press/bench, deadlift progressing to power cleans. Takes lifter profile (sex, bodyweight, age, training days) and optional starting weights. Returns a week-by-week program with progression scheme and coaching notes. Powered by CoachSync.io.

Input parameters:

- `age` (number, required): Lifter's age in years
- `bodyweightLb` (number, required): Lifter's bodyweight in pounds
- `sex` (string, required): Biological sex, used for estimating starting weights and progression rates
- `startingBench` (number): Optional starting bench work weight. If omitted, estimated from bodyweight.
- `startingDeadlift` (number): Optional starting deadlift work weight. If omitted, estimated from bodyweight.
- `startingPress` (number): Optional starting press work weight. If omitted, estimated from bodyweight.
- `startingSquat` (number): Optional starting squat work weight. If omitted, estimated from bodyweight.
- `trainingDays` (number): Training days per week. 3 is standard, 2 is an alternative for recovery-limited trainees.
