AI agents call vpn_status to retrieve information from Bybit Ws without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries VPN health metrics and returns status information without creating, modifying, deleting, or executing any changes. The tool performs pure data retrieval similar to monitoring/observability functions, making it a Read category risk. Severity is low since unauthorized access to VPN status data has limited immediate impact compared to financial or destructive operations.
From the tool's definition Tool retrieves VPN status information: 'service status, traffic rates, connected clients' - these are read-only queries with no state modification.
Attacks that exploit this kind of access
Get VPN health: service status, traffic rates, connected clients. It is categorised as a Read tool in the Bybit Ws MCP Server, which means it retrieves data without modifying state.
Register the Bybit Ws MCP server in PolicyLayer and add a rule for vpn_status: 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 Bybit Ws. Nothing to install.
vpn_status 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 vpn_status 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 vpn_status. 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.
vpn_status is provided by the Bybit Ws MCP server (poliakarmai/bybit-ws). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
