列出所有活跃的扫描任务
AI agents call list_active_scans to retrieve information from MCP Port Scanner without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves metadata about existing scans without initiating new scans, modifying configurations, or causing network side effects. It is purely informational (Read category). Severity is low because listing scan tasks poses minimal security risk—the worst case is information disclosure of which scans are running, which does not directly compromise systems.
From the tool's definition Tool name 'list_active_scans' and description '列出所有活跃的扫描任务' (list all active scan tasks) indicate retrieval of scan status information with no modification or execution of network operations.

Register the MCP Port Scanner MCP server in PolicyLayer and add a rule for list_active_scans: 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 MCP Port Scanner. Nothing to install.
list_active_scans 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 list_active_scans 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 list_active_scans. 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.
list_active_scans is provided by the MCP Port Scanner MCP server (relaxcloud-cn/mcp-port-scanner). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
