Build the URL where the payer authorizes a consent at their bank. This is a helper — it does not call Iniciador. Returns the standard OFB authorization URL using the consent id + redirect URI.
AI agents call get_authorization_url 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 is a helper function that retrieves/constructs a URL for display or redirect purposes. It has no side effects, does not modify any state, does not execute financial transactions, and does not trigger external operations. The actual authorization happens elsewhere (at the bank via the returned URL, by the user). The tool itself merely assembles and returns a read-only authorization endpoint.
From the tool's definition Tool description states it 'Build[s] the URL' and 'Returns the standard OFB authorization URL' — it constructs and returns a URI string without executing any API calls ('does not call Iniciador') or modifying data.
Documented attack patterns abuse exactly the kind of access get_authorization_url gives an agent:
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_authorization_url:
{
"version": "1",
"default": "deny",
"tools": {
"get_authorization_url": {}
}
}get_authorization_url is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Build the URL where the payer authorizes a consent at their bank. This is a helper — it does not call Iniciador. Returns the standard OFB authorization URL using the consent id + redirect URI. It is categorised as a Read tool in the Mcp Afip MCP Server, which means it retrieves data without modifying state.
Register the Mcp Afip MCP server in PolicyLayer and add a rule for get_authorization_url: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Afip. Nothing to install.
get_authorization_url is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_authorization_url rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_authorization_url. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_authorization_url is provided by the Mcp Afip MCP server (codespar/mcp-dev-latam). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Afip, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
