  • search_docs

  • call_api

    Hace una solicitud real a la API en modo de pruebas con la llave fk_test_ de la persona (nunca una fk_live_) y devuelve el código, el Request-Id y el JSON de la respuesta. Para probar un cuerpo antes de escribir el código. Timbra con el emisor de pruebas del SAT, sin costo.

  • list_pages

    Todas las páginas de la documentación: guías y referencia, con su ruta y de qué tratan.

Common questions

Is Fiscalisto API docs safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP
