gateway_target_list
AI agents call gateway_target_list to retrieve information from Amazon ElastiCache Memcached MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the tool name alone, 'gateway_target_list' most likely retrieves or enumerates a list of gateway targets from the ElastiCache infrastructure—a Read operation with no data modification. However, confidence is reduced due to the absent description. The tool could theoretically Write or Execute if it performs unexpected operations, but there is no evidence of this in the available information.
From the tool's definition Tool name 'gateway_target_list' suggests listing or querying gateway targets. Description is empty, limiting certainty. The naming pattern (verb_noun_list) is typical of Read operations that retrieve data without side effects.
Attacks that exploit this kind of access
gateway_target_list. It is categorised as a Read tool in the Amazon ElastiCache Memcached MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon ElastiCache Memcached 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 ElastiCache Memcached 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 ElastiCache Memcached MCP Server MCP server (awslabs.memcached-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
