WHAT IT DOES

What secure_esm_sqs_policy does on Amazon Bedrock Knowledge Base Retrieval MCP Server

AI agents use secure_esm_sqs_policy to create or update resources in Amazon Bedrock Knowledge Base Retrieval MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon Bedrock Knowledge Base Retrieval MCP Server environment.

THE RISK

Medium Risk

Why secure_esm_sqs_policy needs a policy

The tool generates (creates/writes) an IAM policy document. Creating or attaching IAM policies is a Write operation that modifies access control configurations. While generating a policy document could be read-like if it only returns a template, the context of 'Generate...IAM policy' implies creation/attachment of a policy, making it a Write.

From the tool's definition Generate security-approved IAM policy for SQS ESM with scoped permissions. Uses pre-approved templates, not LLM generation.

POLICY

How to control secure_esm_sqs_policy

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Bedrock Knowledge Base Retrieval MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for secure_esm_sqs_policy:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "secure_esm_sqs_policy": {
      "limits": [
        {
          "counter": "secure_esm_sqs_policy_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

secure_esm_sqs_policy stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about secure_esm_sqs_policy

What does the secure_esm_sqs_policy tool do? +

Generate security-approved IAM policy for SQS ESM with scoped permissions. Uses pre-approved templates, not LLM generation. It is categorised as a Write tool in the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on secure_esm_sqs_policy? +

Register the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP server in PolicyLayer and add a rule for secure_esm_sqs_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 Bedrock Knowledge Base Retrieval MCP Server. Nothing to install.

What risk level is secure_esm_sqs_policy? +

secure_esm_sqs_policy is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit secure_esm_sqs_policy? +

Yes. Add a rate_limit block to the secure_esm_sqs_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.

How do I block secure_esm_sqs_policy completely? +

Set action: deny in the PolicyLayer policy for secure_esm_sqs_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.

What MCP server provides secure_esm_sqs_policy? +

secure_esm_sqs_policy is provided by the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP server (awslabs.bedrock-kb-retrieval-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
