Retrieves cost anomalies detected by AWS Cost Anomaly Detection.
AI agents call get_cost_anomalies to retrieve information from AWS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns cost anomaly data without side effects. It performs no financial transactions, code execution, data modification, or destructive operations. The blast radius of misuse is minimal—an agent could observe unexpected spending patterns but cannot alter infrastructure, incur charges, or execute operations. Classification as Read with low severity is appropriate.
From the tool's definition Tool name 'get_cost_anomalies' and description 'Retrieves cost anomalies detected by AWS Cost Anomaly Detection' explicitly indicate a read-only retrieval operation.
Attacks that exploit this kind of access
Retrieves cost anomalies detected by AWS Cost Anomaly Detection. It is categorised as a Read tool in the AWS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS MCP Server MCP server in PolicyLayer and add a rule for get_cost_anomalies: 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 AWS MCP Server. Nothing to install.
get_cost_anomalies 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_cost_anomalies 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_cost_anomalies. 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_cost_anomalies is provided by the AWS MCP Server MCP server (sergiosediq/aws-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
