Get BADLAR rate (tasa de plazos fijos >1M ARS, bancos privados) — used as benchmark for many financial products
AI agents call get_badlar_rate to retrieve information from Mcp Ap2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool fetches a publicly-available benchmark interest rate (BADLAR) for informational/reference purposes. It performs no writes, executions, or financial transactions. Severity is low because misuse only results in reading rate data, with no blast radius.
From the tool's definition 'Get BADLAR rate' — retrieves a benchmark interest rate (tasa de plazos fijos >1M ARS, bancos privados); purely a data lookup with no side effects
Documented attack patterns abuse exactly the kind of access get_badlar_rate gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for get_badlar_rate:
{
"version": "1",
"default": "deny",
"tools": {
"get_badlar_rate": {}
}
}get_badlar_rate is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get BADLAR rate (tasa de plazos fijos >1M ARS, bancos privados) — used as benchmark for many financial products. It is categorised as a Read tool in the Mcp Ap2 MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ap2 MCP server in PolicyLayer and add a rule for get_badlar_rate: 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 Ap2. Nothing to install.
get_badlar_rate 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_badlar_rate 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_badlar_rate. 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_badlar_rate is provided by the Mcp Ap2 MCP server (@codespar/mcp-ap2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Ap2, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
