AI agents call esm_optimize to retrieve information from AWS Serverless MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though esm_optimize only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Comprehensive ESM optimization tool combining analysis, validation, and template generation. This consolidated tool provides three main optimization functions: 1. Analyze configuration tradeoffs for optimization targets 2. Validate ESM configurations against AWS limits and best practices 3. Generate SAM templates for ESM updates Args: ctx: MCP context for logging action: Type of optimization action to perform optimization_targets: List of optimization goals for analysis event_source: Event source type for validation configs: Configuration to validate esm_uuid: ESM UUID for template generation optimized_configs: Optimized configuration for template region: AWS region project_name: Project name for generated templates Returns: Dict containing optimization results, validation status, or SAM template. It is categorised as a Read tool in the AWS Serverless MCP Server MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for esm_optimize. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS Serverless MCP Server MCP server.
esm_optimize 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 esm_optimize rule in your Intercept 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 Intercept policy for esm_optimize. 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.
esm_optimize is provided by the AWS Serverless MCP Server MCP server (awslabs.aws-serverless-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
