Delete a model group and all its models, simulations, and associated data. Permanent, cannot be undone.
AI agents call delete_model_group to permanently remove resources in Sablier 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 multiple categories of data (model groups, models, simulations, and associated data) with no recovery mechanism. The explicit acknowledgment that the action is 'permanent' and 'cannot be undone' places it clearly in the Destructive category rather than Write.
From the tool's definition Tool description explicitly states 'Delete a model group and all its models, simulations, and associated data. Permanent, cannot be undone.' The words 'Delete', 'Permanent', and 'cannot be undone' directly indicate irreversible data destruction.
Attacks that exploit this kind of access
Delete a model group and all its models, simulations, and associated data. Permanent, cannot be undone. It is categorised as a Destructive tool in the Sablier MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Sablier MCP Server MCP server in PolicyLayer and add a rule for delete_model_group: 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 Sablier MCP Server. Nothing to install.
delete_model_group 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_model_group 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_model_group. 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_model_group is provided by the Sablier MCP Server MCP server (sablier-ai/sablier-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
