Delete a flow simulation job (baseline or constrained scenario). Permanent, cannot be undone.
AI agents call delete_flow_job 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 permanently deletes simulation job data without the possibility of recovery. While the blast radius is constrained to simulation job records rather than production financial data, the irreversible nature and explicit permanence statement place it in the Destructive category.
From the tool's definition Tool description explicitly states "Delete a flow simulation job" and "Permanent, cannot be undone." The verb 'delete' combined with the irreversibility clause confirms irreversible data destruction.
Attacks that exploit this kind of access
Delete a flow simulation job (baseline or constrained scenario). 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_flow_job: 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_flow_job 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_flow_job 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_flow_job. 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_flow_job 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.
