AI agents call cost_analyzer to perform operations in Api Request Deduplicator. While the risk category is not fully classified, applying a rate limit gives you visibility into how often the tool is called and prevents unexpected bursts of activity from autonomous agents.
Applying a policy to cost_analyzer gives you an audit trail of every call an AI agent makes. Even for low-risk tools, visibility into agent behaviour helps you debug issues, optimise workflows, and maintain compliance with your organisation's security requirements.
Apply a rate limit to control usage and monitor for unexpected behaviour.

These attack patterns abuse exactly the kind of access cost_analyzer gives an agent. Each links to the full case and the policy that stops it:
Other other tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Analyze API costs and identify savings opportunities. It is categorised as a Other tool in the Api Request Deduplicator MCP Server, which means it performs auxiliary operations.
Register the Api Request Deduplicator MCP server in PolicyLayer and add a rule for cost_analyzer: 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 Api Request Deduplicator. Nothing to install.
cost_analyzer is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the cost_analyzer 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 cost_analyzer. 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.
cost_analyzer is provided by the Api Request Deduplicator MCP server (https://api.lazy-mac.com/api-request-deduplicator/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
