Replace all direct children under a parent Rem. This is destructive because existing child Rem IDs are removed and may be blocked by bridge policy.
AI agents call remnote_replace_children to permanently remove resources in Remnote — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool explicitly states it is destructive and removes existing child Rem IDs, which is an irreversible overwrite of structured knowledge base data. This falls squarely in the Destructive category. The blast radius is high because it can wipe out entire branches of a knowledge base hierarchy in one operation.
From the tool's definition "Replace all direct children under a parent Rem. This is destructive because existing child Rem IDs are removed and may be blocked by bridge policy."
Attacks that exploit this kind of access
Replace all direct children under a parent Rem. This is destructive because existing child Rem IDs are removed and may be blocked by bridge policy. It is categorised as a Destructive tool in the Remnote MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Remnote MCP server in PolicyLayer and add a rule for remnote_replace_children: 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 Remnote. Nothing to install.
remnote_replace_children 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 remnote_replace_children 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 remnote_replace_children. 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.
remnote_replace_children is provided by the Remnote MCP server (remnote-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
