Delete a relation. Specify the collection and field that contains the relation.
AI agents call delete_relation to permanently remove resources in Directus MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes relational metadata/constraints from the database schema. While it does not delete the underlying data in related collections, removing a relation is an irreversible schema modification that breaks data integrity constraints and cannot be easily recovered.
From the tool's definition Tool name is 'delete_relation' with description stating 'Delete a relation.' The verb 'delete' combined with the action of removing a relation between collections is an irreversible operation that cannot be undone without restoring from backup.
Attacks that exploit this kind of access
Delete a relation. Specify the collection and field that contains the relation. It is categorised as a Destructive tool in the Directus MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Directus MCP Server MCP server in PolicyLayer and add a rule for delete_relation: 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 Directus MCP Server. Nothing to install.
delete_relation 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_relation 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_relation. 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_relation is provided by the Directus MCP Server MCP server (skeyelab/directus-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
