Download the boleto PDF as base64. Useful for attaching to emails or portal downloads.
AI agents call get_boleto_pdf to retrieve information from Mcp Ap2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and encodes an existing boleto document for distribution purposes (email attachment, portal download). It does not create, modify, delete, or execute transactions. While the context involves payments (AP2 is a payment protocol), this specific tool only reads/downloads document data. Severity is low because retrieving a PDF carries minimal risk even if misused by an AI agent.
From the tool's definition Tool description states 'Download the boleto PDF as base64' — a retrieval operation with no modification or side effects. Boleto is a Brazilian payment instrument, and downloading/reading it is a data retrieval action.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for get_boleto_pdf:
{
"version": "1",
"default": "deny",
"tools": {
"get_boleto_pdf": {}
}
} get_boleto_pdf is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
