Retrieves daily AWS costs for the specified date range (default: last 7 days).
AI agents call get_recent_cost 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 information without modifying any resources, executing code, or moving money. It is a read-only retrieval operation with minimal blast radius if misused by an AI agent, as it can only expose cost visibility data that is typically already available to authenticated users.
From the tool's definition Tool name 'get_recent_cost' and description 'Retrieves daily AWS costs' indicate data retrieval with no modification. Server is explicitly described as 'read-only'.
Attacks that exploit this kind of access
Retrieves daily AWS costs for the specified date range (default: last 7 days). 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_recent_cost: 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_recent_cost 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_recent_cost 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_recent_cost. 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_recent_cost 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.
