What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

          <label><span>Años de aportes <i title="Años reconocidos por ANSES">i</i></span><select id="years" aria-label="Años de aportes">{Array.from({length:31},(_,i)=>20+i).map(y=><option value={y} selected={y===30}>{y} años</option>)}</select></label>

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

No. Hacé Cuentas — Free Calculators completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

It answers our handshake in 244 ms on average, which is faster than 58% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
