Get Cursor client version distribution across the team: which versions are in use and what percentage of users are on each.
AI agents call get_client_versions to retrieve information from Cursor Usage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query that retrieves and aggregates existing data about client versions. It has no capability to modify, delete, or execute operations. The information returned (version distribution and user percentages) is non-sensitive aggregated telemetry suitable for monitoring purposes. Low severity due to minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'get_client_versions' and description 'Get Cursor client version distribution' indicate a retrieval operation with no side effects. The function queries and reports version statistics without modifying any data.
Attacks that exploit this kind of access
Get Cursor client version distribution across the team: which versions are in use and what percentage of users are on each. It is categorised as a Read tool in the Cursor Usage MCP Server, which means it retrieves data without modifying state.
Register the Cursor Usage MCP server in PolicyLayer and add a rule for get_client_versions: 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 Cursor Usage. Nothing to install.
get_client_versions 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_client_versions 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_client_versions. 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_client_versions is provided by the Cursor Usage MCP server (ofershap/cursor-usage). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
