GetServerInfo
AI agents call GetServerInfo 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.
GetServerInfo appears to retrieve server metadata or configuration information from an Amazon MQ broker without modifying state. The absence of mutating verbs (create, update, delete, execute) and the pattern of sibling analysis/query tools supports a Read classification. Severity is low because reading server info has minimal blast radius even if misused by an agent.
From the tool's definition Tool name 'GetServerInfo' with 'Get' prefix indicates a retrieval operation. The sibling tools include 'get_*' patterns typical of read-only data access (aggregate, analyze_*). The Amazon MQ context suggests querying broker/server information.
Attacks that exploit this kind of access
GetServerInfo. 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 GetServerInfo: 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.
GetServerInfo 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 GetServerInfo 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 GetServerInfo. 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.
GetServerInfo 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.
