gateway_get
AI agents call gateway_get 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 'get' verb and READ-category sibling tools (ActivateAHOReadSets, add_inline_policy, aggregate, analyze_*) on this server suggest this is a retrieval operation. However, confidence is moderate (0.6) because the description is empty and 'gateway_get' could theoretically involve executing queries or operations depending on implementation details.
From the tool's definition Tool name 'gateway_get' suggests a read operation (GET is a standard HTTP method for retrieval). Server context is Amazon MQ (message broker management). The suffix 'get' indicates data retrieval rather than modification or execution.
Attacks that exploit this kind of access
gateway_get. 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_get: 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_get 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_get 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_get. 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_get 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.
