WHAT IT DOES

What get_quote does on Mcp Afip

AI agents call get_quote 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 get_quote needs a policy

This tool retrieves price information and market data without modifying state, executing operations, or committing financial transactions. It is a read-only query operation. The low severity reflects minimal blast radius—misuse would only expose the user to stale or inaccurate pricing information, not financial loss or data corruption.

From the tool's definition Tool description explicitly states it 'Get a fiat↔crypto price quote (public, no auth)' and 'Returns the rate, fees, min/max, delivery network' — purely informational retrieval with no side effects.

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

POLICY

How to control get_quote

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_quote:

policy.json

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

get_quote 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.

Questions about get_quote

What does the get_quote tool do? +

Get a fiat↔crypto price quote (public, no auth). Returns the rate, fees, min/max, delivery network, and the exact cryptoAmount the buyer receives for a given fiatAmount (or vice versa). Use this before calling create_order to show the user a price they can confirm. It is categorised as a Read tool in the Mcp Afip MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_quote? +

Register the Mcp Afip MCP server in PolicyLayer and add a rule for get_quote: 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 get_quote? +

get_quote is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_quote? +

Yes. Add a rate_limit block to the get_quote 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 get_quote completely? +

Set action: deny in the PolicyLayer policy for get_quote. 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 get_quote? +

get_quote 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.
