Query the installment plans Getnet offers for a given amount + card brand (with/without interest, max installments, per-installment amount).
AI agents call query_installments 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.
This tool retrieves installment plan details (interest rates, maximum installments, per-installment amounts) from Getnet's system. It reads and presents payment options without executing payments, creating obligations, or modifying any data. The worst-case misuse by an AI agent would be extracting installment plan information, which poses minimal risk.
From the tool's definition Tool name is 'query_installments' and description states it 'Query[ies] the installment plans' — a retrieval operation that returns information about installment offerings without modifying, executing, or committing financial transactions.
Documented attack patterns abuse exactly the kind of access query_installments 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 query_installments:
{
"version": "1",
"default": "deny",
"tools": {
"query_installments": {}
}
}query_installments is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Query the installment plans Getnet offers for a given amount + card brand (with/without interest, max installments, per-installment amount). 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 query_installments: 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.
query_installments 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 query_installments 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 query_installments. 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.
query_installments 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.
Free to start. No card required.
