policy_get
AI agents call 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.
The tool name 'policy_get' follows standard naming conventions for read operations (similar to HTTP GET semantics). Getting policy information is a non-destructive retrieval that queries existing data without side effects. Absent evidence to the contrary, and given the 'get' verb convention, this is classified as a Read operation with low severity, as policy retrieval does not modify data or trigger external actions.
From the tool's definition Tool name 'policy_get' suggests a retrieval operation. The 'get' verb indicates querying or fetching data without modification. Description is empty, which slightly reduces confidence, but the naming convention strongly suggests a read operation.
Attacks that exploit this kind of access
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 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.
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 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 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.
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.
