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.

Runs an external command worker-configuration.d.ts:3387
    exec(input?: string | URLPatternInit, baseURL?: string): URLPatternResult | null;

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.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

validar
validar_cron
Calcula las próximas ejecuciones reales de una expresión cron usando cron-parser (no una suposición del modelo sobre cuándo dispararía). Interpreta los campos en UTC para que el resultado no dependa de la zona horaria del servidor que corre la tool. Cuesta $0.02 USDC (Base) por llamada.
validar_regex
Ejecuta un patrón de expresión regular (motor nativo de JavaScript) contra una lista de strings de prueba y devuelve, para cada uno, si hizo match, el match completo y los grupos capturados. Usa RegExp real, no una suposición del modelo sobre qué haría el patrón. Cuesta $0.02 USDC (Base) por llamada.
validar_sql
Ejecuta una consulta SQL (dialecto Postgres, motor pg-mem en memoria) contra tablas de prueba opcionales y devuelve las filas reales resultantes. Usa un motor SQL real, no una suposición del modelo sobre qué devolvería la query. Sin base de datos persistente: las tablas se crean desde cero en cada llamada y se descartan al terminar. Cuesta $0.04 USDC (Base) por llamada.

regexcronsql-validator — questions

Answers built from our own checks of this server.

What can regexcronsql-validator do?
It exposes 3 tools, read directly from the server on our last check. Among them: validar_cron, validar_regex, validar_sql. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is regexcronsql-validator working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 81 ms. The bar chart above shows every period we have measured.
The registry lists regexcronsql-validator as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect regexcronsql-validator?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does regexcronsql-validator need an API key?
No. regexcronsql-validator 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.
Is regexcronsql-validator open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at regexcronsql-validator.encodari.workers.dev, which runs on its operator's own terms.
