WHAT IT DOES

What sam_logs does on Amazon Bedrock Knowledge Base Retrieval MCP Server

AI agents call sam_logs to retrieve information from Amazon Bedrock Knowledge Base Retrieval MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why sam_logs needs a policy

The tool appears to retrieve or query logs, which is a read-only operation with no side effects. The empty description reduces confidence slightly, but the context of a Knowledge Base Retrieval server and the naming pattern strongly indicate a read operation. Log retrieval has minimal blast radius if misused—an AI agent might retrieve sensitive logs but cannot modify or delete them with this tool alone.

From the tool's definition Tool name 'sam_logs' suggests retrieval of AWS SAM (Serverless Application Model) logs. The description is empty, but the naming convention aligns with log retrieval/querying operations.

Documented attack patterns abuse exactly the kind of access sam_logs gives an agent:

POLICY

How to control sam_logs

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 sam_logs:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sam_logs": {}
  }
}

sam_logs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
