Download a guía label as PDF (returns base64 or URL)
AI agents call get_guia_pdf to retrieve information from Mcp Afip without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a guía (shipping/transport document) in PDF format. It performs a read-only operation with no side effects—it neither modifies data, executes external commands, deletes records, nor moves funds. The output is base64-encoded or a URL reference to an existing document. While the document may contain sensitive tax/logistics information, the tool itself is purely a retrieval mechanism.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Afip, and nothing reaches the server without passing your rules. This is the rule we recommend for get_guia_pdf:
{
"version": "1",
"default": "deny",
"tools": {
"get_guia_pdf": {}
}
} get_guia_pdf is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
