Analyze Lambda function costs and identify optimization opportunities
AI agents call get_cost_analysis to retrieve information from Lambda Performance MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes cost data from AWS Lambda to provide insights. It does not create, modify, delete, or trigger any operations on Lambda functions or resources. Cost analysis is a read-only, informational operation that presents existing metrics to the user for decision-making.
From the tool's definition Tool name 'get_cost_analysis' and description 'Analyze Lambda function costs and identify optimization opportunities' indicate data retrieval and analysis only.
Attacks that exploit this kind of access
Analyze Lambda function costs and identify optimization opportunities. It is categorised as a Read tool in the Lambda Performance MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Lambda Performance MCP Server MCP server in PolicyLayer and add a rule for get_cost_analysis: 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 Lambda Performance MCP Server. Nothing to install.
get_cost_analysis 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_analysis 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_analysis. 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_analysis is provided by the Lambda Performance MCP Server MCP server (jghidalgo/lambda-performance-mcp-nodejs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
