WHAT IT DOES

What create_check does on Mcp Afip

AI agents invoke create_check to trigger actions in Mcp Afip. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

High Risk

Why create_check needs a policy

The tool triggers an external verification workflow (KYC/AML checks involving document verification, facial similarity, watchlist screening). This is not a simple read or write — it executes an external process with downstream consequences (applicant flagged, compliance records created, potentially blocking or approving individuals).

From the tool's definition "Run a verification check on an applicant" and "actually triggers the verification" — this initiates an external identity/compliance verification process with real-world effects

Documented attack patterns abuse exactly the kind of access create_check gives an agent:

POLICY

How to control create_check

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 create_check:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_check": {
      "limits": [
        {
          "counter": "create_check_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

create_check stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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.

FAQ

Questions about create_check

What does the create_check tool do? +

Run a verification check on an applicant. A check is a bundle of one or more reports (document, facial_similarity_photo, watchlist, etc). This is the step that actually triggers the verification. It is categorised as a Execute tool in the Mcp Afip MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_check? +

Register the Mcp Afip MCP server in PolicyLayer and add a rule for create_check: 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.

What risk level is create_check? +

create_check is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit create_check? +

Yes. Add a rate_limit block to the create_check 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.

How do I block create_check completely? +

Set action: deny in the PolicyLayer policy for create_check. 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.

What MCP server provides create_check? +

create_check 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.
