Free strength-training calculators, plus a checker for program files you import into IronLedger.
IronLedger strength calculators's hosted MCP server (www.ironledger.app), published by ironledger.app; no sign-in required; Streamable HTTP; 7 tools.
No AI overview yet: these facts come from the registry entry and the server itself.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/app.ironledger%2Fstrength-calculators/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}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.
repsrequiredunitweightrequiredformulaEstimate 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.
rperequiredrepsrequiredunitweightrequiredformulaLoad 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.

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.
barunitplatestargetrequiredcollarscollarWeightWarm-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.

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.

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.
filerequiredfileName83% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.
A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
