清空已加载的 pipeline 节点。
AI agents call clear_pipeline_resources to permanently remove resources in MaaMCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes loaded pipeline node resources. Given the context of an automation framework (MaaFramework) for Android and Windows automation, clearing pipeline resources would irreversibly delete configuration or operational state that cannot be easily recovered.
From the tool's definition Tool name 'clear_pipeline_resources' combined with description '清空已加载的 pipeline 节点' (clear/empty loaded pipeline nodes). The verb '清空' (clear/empty) indicates irreversible removal of resources.

Register the Maa MCP server in PolicyLayer and add a rule for clear_pipeline_resources: 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 MaaMCP. Nothing to install.
clear_pipeline_resources 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 clear_pipeline_resources 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 clear_pipeline_resources. 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.
clear_pipeline_resources is provided by the Maa MCP server (maa-ai/maamcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
