AI agents use update_subscription to create or modify resources in PineLabs Plural PG — Payment Gateway MCP Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call update_subscription repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach PineLabs Plural PG — Payment Gateway MCP Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches PineLabs Plural PG — Payment Gateway MCP Server. Nothing to install.
update_subscription is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_subscription 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 update_subscription. 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.
