regexcronsql-validator is an MCP server with 3 tools an agent can call, among them validar_cron, validar_regex, validar_sql. It answers at https://regexcronsql-validator.encodari.workers.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Valida regex, cron y SQL contra ejecucion real. Pago por llamada via x402/USDC.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 Inputs: cron_expression, from_date, count |
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 sob Inputs: pattern, flags, test_strings |
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 Inputs: query, tables |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://regexcronsql-validator.encodari.workers.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
