AI agents call get_payment_intent to retrieve information from Paymongo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing payment intent data without modifying, deleting, or executing any financial transactions. It is a read-only operation that queries the PayMongo API for information about a specific payment intent. Although it operates in a financial context, the tool itself performs no financial action (no money movement, no commitments).
From the tool's definition Tool name is 'get_payment_intent' and description states 'Retrieve a PayMongo payment intent by its ID' — a query operation with no side effects.

Register the Paymongo MCP server in PolicyLayer and add a rule for get_payment_intent: 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 Paymongo. Nothing to install.
get_payment_intent 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_payment_intent 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_payment_intent. 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_payment_intent is provided by the Paymongo MCP server (theyahia/paymongo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
