Generate SAM template with security group rules for MSK ESM connectivity. Creates CloudFormation resources for security group ingress and egress rules that allow proper communication between Lambda ESM and MSK cluster. The rules enable HTTPS (443) and Kafka broker (9092-9098) traffic. Args: ...
Part of the AWS Serverless MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call esm_msk_security_group 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_msk_security_group 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.

Generate SAM template with security group rules for MSK ESM connectivity. Creates CloudFormation resources for security group ingress and egress rules that allow proper communication between Lambda ESM and MSK cluster. The rules enable HTTPS (443) and Kafka broker (9092-9098) traffic. Args: ctx: MCP context for logging security_group_id: ID of the security group attached to MSK cluster Returns: Dict containing complete SAM template with security group rules. 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_msk_security_group. 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_msk_security_group 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_msk_security_group 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_msk_security_group. 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_msk_security_group 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.
