Remove a field from a collection. This will delete the column and all its data. Use with caution.
AI agents call delete_field 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 and irreversibly deletes data at the field/column level across all records in a collection. There is no undo or recovery mechanism implied. This is definitively a destructive operation—the most severe category. The blast radius is critical because an AI agent could accidentally or maliciously remove important data structures and all associated records with a single call.
From the tool's definition Tool description states it will 'delete the column and all its data' and explicitly warns 'Use with caution.' The tool name 'delete_field' combined with the destructive action of irreversibly removing both schema and data from a collection.
Attacks that exploit this kind of access
Remove a field from a collection. This will delete the column and all its data. Use with caution. 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_field: 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_field 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_field 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_field. 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_field 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.
