AI agents call audit_slos 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.
Without a description, confidence is reduced. However, 'audit' typically implies inspection/review rather than modification or execution. The tool name suggests examining SLO data rather than creating, executing, or destroying resources. Classified as Read with low severity due to limited blast radius if misused, though higher confidence would require a functional description.
From the tool's definition Tool name 'audit_slos' suggests querying or reviewing Service Level Objectives; the empty description provides no indication of side effects, and the server context (Bedrock Knowledge Base Retrieval) implies data retrieval operations.
Documented attack patterns abuse exactly the kind of access audit_slos gives an agent:
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 audit_slos:
{
"version": "1",
"default": "deny",
"tools": {
"audit_slos": {}
}
} audit_slos is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

audit_slos. It is categorised as a Read tool in the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP server in PolicyLayer and add a rule for audit_slos: 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.
audit_slos 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 audit_slos 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 audit_slos. 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.
audit_slos 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.
Start from Amazon Bedrock Knowledge Base Retrieval MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
