Changes things 6Creates or changes something that can be changed back.Claude Code: ask

check_program_fileCheck 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.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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.

one_rep_maxEstimate a one-rep max (1RM) from a set of weight × reps, with a percentage table and the load each rep count should allow.No findings

Description, as the server wrote it
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.

plate_loadingWork 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.No findings

rpe_target_loadFind the load for a set of a given number of reps at a target RPE, from a known or estimated one-rep max.No findings
Why it is in this group
- The description's first verb is "find": a word for reading.
Description, as the server wrote it
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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as strength-calculators. Review it before you use it.

6 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
