清空临时封锁 IP，并强制要求显式确认。
AI agents call block_clear_temp to permanently remove resources in AF_MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool clears temporary IP blocks, which is an irreversible action that removes security protections. Even though blocks are 'temporary' in nature, actively clearing them is a destructive operation that cannot be undone and directly impacts security posture. The requirement for explicit confirmation further underscores the severity of this action.
From the tool's definition Tool name 'block_clear_temp' combined with description indicating clearing of temporary blocked IPs ('清空临时封锁 IP'). The operation irreversibly removes blocking rules that protect the security device.

Register the AF_ MCP server in PolicyLayer and add a rule for block_clear_temp: 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 AF_MCP. Nothing to install.
block_clear_temp is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the block_clear_temp 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 block_clear_temp. 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.
block_clear_temp is provided by the AF_ MCP server (xiaqijun/af_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
