WHAT IT DOES

What consult_fgts does on Mcp Afip

AI agents call consult_fgts 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 RISK

Low Risk

Why consult_fgts needs a policy

Although this tool accesses sensitive financial data (FGTS worker savings accounts), it performs only data retrieval with no side effects. This qualifies it as Read rather than Financial, since no money is moved or obligations created. However, the medium severity reflects the fact that unauthorized access to worker financial records could enable fraud, identity theft, or data misuse.

From the tool's definition Tool name 'consult_fgts' and description 'Query FGTS balance / extrato' indicate a retrieval operation with no modification. The verb 'Query' and 'consult' are explicit read operations.

POLICY

How to control consult_fgts

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 consult_fgts:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "consult_fgts": {}
  }
}

consult_fgts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Afip — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
