## 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 2026-11-05.

- **Endpoint Security**: 83/100
  - 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 62/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1369 tokens (~195/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 67/100
  - Stability observed for 20 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (7)

### `one_rep_max` (~160 tokens)

One-rep max calculator

Estimate a one-rep max (1RM) from a set of weight × reps, with a percentage table and the load each rep count should allow. Epley by default, Brzycki optional. Estimates above 10 reps are flagged as less reliable.

Input parameters:

- `formula` (string): One-rep max formula: epley (weight × (1 + reps ÷ 30), the one the IronLedger app uses) or brzycki (weight × 36 ÷ (37 − reps)).
- `reps` (integer, required): Reps completed, 1 to 30.
- `unit` (string): Weight unit for every load in and out: kg or lb.
- `weight` (number, required): Weight lifted for the set.

### `rpe_estimate_max` (~195 tokens)

Estimate one-rep max from a set and its RPE

Estimate a one-rep max from weight, reps and RPE, treating RPE as reps in reserve (RPE 8 = 2 reps left) and applying the one-rep max formula to reps + reps in reserve.

Input parameters:

- `formula` (string): One-rep max formula: epley (weight × (1 + reps ÷ 30), the one the IronLedger app uses) or brzycki (weight × 36 ÷ (37 − reps)).
- `reps` (integer, required): Reps completed, 1 to 20.
- `rpe` (number, required): Rating of perceived exertion, 5 to 10, read as reps in reserve (RPE 8 = 2 reps left). Half points allowed.
- `unit` (string): Weight unit for every load in and out: kg or lb.
- `weight` (number, required): Weight lifted for the set.

### `rpe_target_load` (~189 tokens)

Load for a target reps and RPE

Find the load for a set of a given number of reps at a target RPE, from a known or estimated one-rep max. Rounded to the nearest 0.5.

Input parameters:

- `formula` (string): One-rep max formula: epley (weight × (1 + reps ÷ 30), the one the IronLedger app uses) or brzycki (weight × 36 ÷ (37 − reps)).
- `oneRepMax` (number, required): Your one-rep max (tested or estimated).
- `reps` (integer, required): Target reps, 1 to 20.
- `rpe` (number, required): Rating of perceived exertion, 5 to 10, read as reps in reserve (RPE 8 = 2 reps left). Half points allowed.
- `unit` (string): Weight unit for every load in and out: kg or lb.

### `plate_loading` (~227 tokens)

Barbell plate calculator

Work out which plates to put on each side of a barbell to reach a target weight, using standard gym plates or the plates you list. Reports the exact load and anything your plates can’t make.

Input parameters:

- `bar` (number): Bar weight in the chosen unit. Defaults to 20 kg or 45 lb.
- `collarWeight` (number): Weight of each collar. Defaults to 2.5 kg or 5 lb.
- `collars` (boolean): Count a collar on each side.
- `plates` (string): Plates available, heaviest first or in any order: "25,20,15,10,5,2.5,1.25" for as many as needed, or "25:4,20:2" for pairs owned. Defaults to standard gym plates (kg: 25 to 1.25; lb: 45 to 2.5).
- `target` (number, required): Total weight wanted on the bar, including the bar.
- `unit` (string): Weight unit for every load in and out: kg or lb.

### `warmup_sets` (~121 tokens)

Warm-up set calculator

Build a warm-up ramp to a working weight: plate-friendly jumps, reps falling from 10 to singles, with the plates for each set. The same ramp the IronLedger app suggests.

Input parameters:

- `bar` (number): Bar weight in the chosen unit. Defaults to 20 kg or 45 lb.
- `sets` (integer): Number of warm-up sets, 1 to 12.
- `unit` (string): Weight unit for every load in and out: kg or lb.
- `workingWeight` (number, required): The first working set’s weight.

### `powerlifting_score` (~165 tokens)

DOTS, IPF GL and Wilks calculator

Score a powerlifting total (or a bench press) against bodyweight with DOTS, IPF GL points and the original Wilks, using the coefficients the OpenPowerlifting rankings use.

Input parameters:

- `bodyweight` (number, required): Bodyweight in the chosen unit.
- `equipment` (string): For IPF GL: raw (classic) or equipped.
- `event` (string): For IPF GL: sbd (full powerlifting total) or bench (bench press only).
- `sex` (string, required): The formulas have separate male and female coefficients.
- `total` (number, required): Total lifted (squat + bench + deadlift), or the bench press for event "bench".
- `unit` (string): Weight unit for every load in and out: kg or lb.

### `check_program_file` (~252 tokens)

IronLedger program file checker

Check a training program written as a CSV or TSV file exactly as the IronLedger app will import it, before anyone loads it on a phone. Returns the weeks, sessions and exercises it creates, every skipped row and warning with its row number, the exercise names the app will question ("Did you mean ...?"), and names that will become new custom exercises. Use it whenever you write a program for someone to import into IronLedger, and fix anything it reports first. The app names the program after the file, so pass the file name you will give it.

Input parameters:

- `file` (string, required): The whole program file as text. Canonical header: Week,Day,Exercise,Sets,Reps,Load,RPE,RIR,Rest,Notes, then one row per exercise, such as 1,Day 1,Squat,5,5,100 kg,8,,3:00,belt. Wrap a cell that conta…
- `fileName` (string): The file name it will be saved as, such as "Texas Method.csv". The app names the program after it; without one the program is called Imported Spreadsheet.

IronLedger strength calculators scores 82 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the IronLedger strength calculators MCP server expose?

IronLedger strength calculators exposes 7 tools: one_rep_max, rpe_estimate_max, rpe_target_load, plate_loading, warmup_sets, and 2 more. Their descriptions and schemas cost roughly 1,309 tokens of context every time the server is loaded.

### Does the IronLedger strength calculators MCP server require authentication?

No. We connected to IronLedger strength calculators without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the IronLedger strength calculators MCP server still maintained?
