get_user
AI agents call get_user to retrieve information from CATS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Without a description, classification relies on the tool name. The 'get_' prefix conventionally indicates retrieval without side effects. However, empty description reduces confidence. The context of a recruiting/ATS system suggests this retrieves user profile data, which is a Read operation. No indication of data modification, deletion, or financial impact.
From the tool's definition Tool name 'get_user' with empty description suggests a retrieval operation typical of Read category tools like 'get' or 'fetch'.
Attacks that exploit this kind of access
get_user. It is categorised as a Read tool in the CATS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CATS MCP Server MCP server in PolicyLayer and add a rule for get_user: 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 CATS MCP Server. Nothing to install.
get_user 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 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. 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 is provided by the CATS MCP Server MCP server (vanman2024/cats-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
