Generate security-approved IAM policy for DynamoDB Streams ESM with scoped permissions. Uses pre-approved templates, not LLM generation.
AI agents call secure_esm_dynamodb_policy to retrieve information from Amazon MQ MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool generates/returns a policy document using pre-approved templates. It does not apply or attach the policy to any resource — it only produces the policy text for review. This is effectively a read/query operation that returns structured output. No side effects are described. Severity is low since misuse only results in an insecure or incorrect policy being suggested, not applied.
From the tool's definition 'Generate security-approved IAM policy for DynamoDB Streams ESM with scoped permissions. Uses pre-approved templates, not LLM generation.'
Attacks that exploit this kind of access
Generate security-approved IAM policy for DynamoDB Streams ESM with scoped permissions. Uses pre-approved templates, not LLM generation. It is categorised as a Read tool in the Amazon MQ MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon MQ MCP Server MCP server in PolicyLayer and add a rule for secure_esm_dynamodb_policy: 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 Amazon MQ MCP Server. Nothing to install.
secure_esm_dynamodb_policy 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 secure_esm_dynamodb_policy 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 secure_esm_dynamodb_policy. 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.
secure_esm_dynamodb_policy is provided by the Amazon MQ MCP Server MCP server (awslabs.amazon-mq-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
