⚠️ DESTRUCTIVE: Permanently delete a dataset item. This write operation cannot be undone.
AI agents call write_delete_dataset_item to permanently remove resources in Langfuse MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data from a dataset, which is the defining characteristic of the Destructive category. The high severity reflects that an AI agent could accidentally or maliciously purge important dataset items without recovery. Confidence is high due to explicit 'DESTRUCTIVE' warning and clear permanent deletion semantics.
From the tool's definition Tool name includes 'delete'; description explicitly states '⚠️ DESTRUCTIVE: Permanently delete a dataset item. This write operation cannot be undone.' The keyword 'Permanently' and 'cannot be undone' clearly indicate irreversible data deletion.
Attacks that exploit this kind of access
⚠️ DESTRUCTIVE: Permanently delete a dataset item. This write operation cannot be undone. It is categorised as a Destructive tool in the Langfuse MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Langfuse MCP Server MCP server in PolicyLayer and add a rule for write_delete_dataset_item: 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 Langfuse MCP Server. Nothing to install.
write_delete_dataset_item 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 write_delete_dataset_item 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 write_delete_dataset_item. 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.
write_delete_dataset_item is provided by the Langfuse MCP Server MCP server (therealsachin/langfuse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
