Clear all datasets and cached data from current session
AI agents call clear_all_data to permanently remove resources in MCP DS Toolkit Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes all datasets and cached data without the ability to recover them from the session. This is a destructive operation that cannot be undone and represents a high blast radius if invoked unintentionally by an AI agent, as it wipes the entire working dataset collection.
From the tool's definition Tool name is 'clear_all_data' and description states 'Clear all datasets and cached data from current session' — the verb 'clear' combined with 'all datasets' indicates irreversible deletion of data.

Clear all datasets and cached data from current session. It is categorised as a Destructive tool in the MCP DS Toolkit Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP DS Toolkit Server MCP server in PolicyLayer and add a rule for clear_all_data: 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 DS Toolkit Server. Nothing to install.
clear_all_data 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_all_data 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_all_data. 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_all_data is provided by the MCP DS Toolkit Server MCP server (yasserelhaddar/mcp-ds-toolkit-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
