AI agents may call delete_resource to permanently remove or destroy resources in Knowledge Graph Server. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call delete_resource in a loop, permanently destroying resources in Knowledge Graph Server. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

Delete resources from the knowledge graph. This tool must be used in conjunction with list_graphs and get_node_details tools, and the operation cannot be undone. Use cases: 1. Delete outdated resource files 2. Clean up unnecessary documents 3. Remove incorrectly created resources Usage recommendations: 1. First call list_graphs to get target graph information 2. Use get_node_details to confirm resource associations 3. Confirm deletion won't affect other nodes 4. Set confirmDelete to true to confirm deletion 5. Recommended to backup important resources before deletion Important notes: - Deleting a resource will also delete the physical file - Will automatically unlink from all nodes - This operation cannot be recovered Return data: - data: Deletion result * id: Deleted resource ID * type: Resource type * deletedAt: Deletion time. It is categorised as a Destructive tool in the Knowledge Graph Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Knowledge Graph Server MCP server in PolicyLayer and add a rule for delete_resource: 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 Knowledge Graph Server. Nothing to install.
delete_resource 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 delete_resource 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 delete_resource. 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.
delete_resource is provided by the Knowledge Graph Server MCP server (aiuluna/knowledge-graph-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
