Delete a specific dataset item. This action is irreversible.
AI agents call deleteDatasetItem to permanently remove resources in Langfuse Mcp Extended — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data without possibility of recovery. Even though the blast radius is limited to individual dataset items rather than entire datasets, the irreversible nature and permanent data loss make this Destructive rather than Write.
From the tool's definition Tool description explicitly states 'Delete a specific dataset item' and 'This action is irreversible.' The name 'deleteDatasetItem' and irreversible deletion semantics clearly indicate destructive capability.
Attacks that exploit this kind of access
Delete a specific dataset item. This action is irreversible. It is categorised as a Destructive tool in the Langfuse Mcp Extended MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Langfuse Mcp Extended MCP server in PolicyLayer and add a rule for deleteDatasetItem: 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 Extended. Nothing to install.
deleteDatasetItem 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 deleteDatasetItem 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 deleteDatasetItem. 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.
deleteDatasetItem is provided by the Langfuse Mcp Extended MCP server (langfuse-mcp-extended). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
