Preguntas frecuentes

¿Es seguro Untax?

Superó 3 de 3 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.

¿Qué claves o códigos necesita?

El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.

¿Se ejecuta en mi computadora o en la nube?

Se ejecuta en la nube del creador. Te conectas por internet sin instalar nada, pero lo que envías pasa por los servidores del creador.

¿Sigue en mantenimiento?

El repo de GitHub cambió por última vez –, y la última versión (0.4.2) llegó al registro hace 13 días.

¿Qué apps pueden usarlo?

Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.

¿Qué puedo usar en su lugar?

Untax MCP & Agent Plugin (v0.4.4)

Research county property assessments, compare available records, and prepare a free private veteran review PDF from a saved review you select. Missing facts stay visible. A draft does not establish eligibility or authorize filing.

Quick start

  1. Follow the Untax setup guide to connect a supported assistant to https://untax.io/mcp.
  2. Ask about a property's available assessment records, a public VA office, or an official VA form. These public lookups require no account or API key. Check the response for sources and missing information.
  3. If you request a private review or test checkout, follow the browser sign-in link and review the requested permissions.

Version 0.4.4 updates package descriptions and instructions. Existing connections and account permissions are unchanged. Read the release notes or release history.

Package and review status

The release archives install the existing skills and remote connection. The included OpenAI review draft still needs a verified recording and provider checks before submission. Installing this package does not submit it to a directory or change the hosted service.
