SearchRelevantContent
AI agents call SearchRelevantContent 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.
Search operations are retrieval-only and non-destructive. Without any description indicating write, execute, or destructive capabilities, and given the naming convention, this tool most likely queries or filters existing content. The low severity reflects minimal blast radius if misused—it cannot modify data, execute code, or cause financial harm.
From the tool's definition Tool name 'SearchRelevantContent' indicates a search/query operation with no modification or execution semantics. The empty description reduces confidence, but the name itself strongly suggests data retrieval rather than side effects.

SearchRelevantContent. 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 SearchRelevantContent: 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.
SearchRelevantContent 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 SearchRelevantContent 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 SearchRelevantContent. 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.
SearchRelevantContent 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.
