Remove a subscriber from your publication by email or wallet address. This is a hard delete and cannot be undone — always confirm with the user before calling. Tip: call
AI agents call remove-subscriber to permanently remove resources in Paragraph MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes subscriber records with no undo capability. Although the blast radius is limited to subscriber account removal (not financial impact or broad data destruction), the permanent nature of the operation and the instruction to 'always confirm with the user before calling' classify it as Destructive rather than Write.
From the tool's definition Tool description states 'Remove a subscriber from your publication by email or wallet address. This is a hard delete and cannot be undone' — explicitly irreversible deletion of subscriber data.

remove-subscriber 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 remove-subscriber 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.
