get_user_policy
AI agents call get_user_policy to retrieve information from Awslabs Valkey without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name suggests retrieving user policy information from AWS IAM, which is a read operation with no side effects. While the description is uninformative, the 'get_' prefix and the context of an MCP server managing AWS resources strongly indicate this retrieves policy data without modification. The low confidence penalty reflects the missing description.
From the tool's definition Tool name 'get_user_policy' and pattern of sibling Read tools (aggregate, analyze_*) indicate data retrieval. Description is empty, limiting confidence. However, 'get' semantics consistently indicate read-only operations.
Attacks that exploit this kind of access
get_user_policy. It is categorised as a Read tool in the Awslabs Valkey MCP Server, which means it retrieves data without modifying state.
Register the Awslabs Valkey MCP server in PolicyLayer and add a rule for get_user_policy: 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 Awslabs Valkey. Nothing to install.
get_user_policy 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 get_user_policy 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 get_user_policy. 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.
get_user_policy is provided by the Awslabs Valkey MCP server (awslabs.valkey-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
