gateway_target_list
AI agents call gateway_target_list 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 name contains 'list', which is characteristic of Read operations that retrieve data without side effects. However, confidence is reduced due to the absence of a description. In the context of an Amazon MQ server managing brokers and gateways, this likely lists gateway targets for informational purposes. No evidence suggests write, delete, execute, or financial operations.
From the tool's definition Tool name 'gateway_target_list' suggests a listing/querying operation typical of Read category tools. The empty description limits certainty, but the naming pattern (list suffix) implies retrieval without modification.

gateway_target_list. 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 gateway_target_list: 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.
gateway_target_list 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 gateway_target_list 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 gateway_target_list. 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.
gateway_target_list 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.
