Delete multiple relations from the knowledge graph
AI agents call delete_relations to permanently remove resources in WebDAV MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of relations from a knowledge graph cannot be undone and permanently removes structured data dependencies and connections. This is categorized as Destructive rather than Write because the action is irreversible. Severity is high because accidental or malicious bulk deletion of relations could corrupt the integrity of the knowledge graph and cascade failures in dependent systems.
From the tool's definition Tool name 'delete_relations' explicitly indicates deletion operation. Description states 'Delete multiple relations from the knowledge graph,' which is an irreversible data destruction action.
Attacks that exploit this kind of access
Delete multiple relations from the knowledge graph. It is categorised as a Destructive tool in the WebDAV MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the WebDAV MCP Server MCP server in PolicyLayer and add a rule for delete_relations: 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 WebDAV MCP Server. Nothing to install.
delete_relations 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_relations 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_relations. 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_relations is provided by the WebDAV MCP Server MCP server (masx200/mcp-webdav-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
