Retrieve metadata for a previously stored card token (brand, last 4, expiration). Does not return the PAN.
AI agents call get_token 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.
The tool performs a query/retrieval of stored token metadata without modifying, deleting, or executing any operations. It explicitly does not expose sensitive PAN data. The blast radius is minimal—an AI agent misusing this would only gain visibility into non-sensitive token details already associated with the account.
From the tool's definition Tool name 'get_token' and description states it 'Retrieve[s] metadata for a previously stored card token' including 'brand, last 4, expiration' but 'Does not return the PAN.' This is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_token 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_token:
{
"version": "1",
"default": "deny",
"tools": {
"get_token": {}
}
}get_token is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve metadata for a previously stored card token (brand, last 4, expiration). Does not return the PAN. 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_token: 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_token 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_token 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_token. 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_token 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.
Free to start. No card required.
