A list of tags applied to the resource.
AI agents call ListTagsForResource 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.
This tool retrieves tag metadata from an AWS resource. It performs a read-only query operation with no capability to modify, delete, or execute actions. The blast radius of misuse is minimal—an attacker could only discover tag information, which may reveal organizational metadata but cannot directly compromise resources or data. This is a standard Read category tool.
From the tool's definition Tool name 'ListTagsForResource' and description 'A list of tags applied to the resource' indicate a retrieval operation that queries existing metadata without modification or side effects.
Attacks that exploit this kind of access
A list of tags applied to the resource. 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 ListTagsForResource: 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.
ListTagsForResource 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 ListTagsForResource 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 ListTagsForResource. 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.
ListTagsForResource 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.
