gateway_resource_policy_get
AI agents call gateway_resource_policy_get 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.
This tool retrieves (gets) resource policy data from an AWS ElastiCache gateway, which is a read-only operation with no side effects. However, resource policies contain sensitive access control information that could be valuable for reconnaissance or privilege escalation planning, elevating severity above 'low'.
From the tool's definition Tool name 'gateway_resource_policy_get' uses 'get' verb which indicates a read operation that retrieves resource policy information. The 'gateway_resource_policy' component suggests it retrieves access control policies from an AWS gateway resource.

gateway_resource_policy_get. 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_resource_policy_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 ElastiCache Memcached MCP Server. Nothing to install.
gateway_resource_policy_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_resource_policy_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_resource_policy_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_resource_policy_get 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.
