DELETE /v1/lists/{object_type}/{list_slug}/{item_id}.
AI agents call remove_list_item to permanently remove resources in DataMerge MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The DELETE HTTP method with a specific item ID indicates irreversible removal of data. This cannot be undone without restoration from backups, making it destructive rather than write (which is reversible). The high severity reflects the blast radius: an agent misconfigured or manipulated to remove list items from critical business lists could cause operational disruption.
From the tool's definition Tool name 'remove_list_item' and API endpoint 'DELETE /v1/lists/{object_type}/{list_slug}/{item_id}' explicitly perform a DELETE operation on a specific list item.
Attacks that exploit this kind of access
DELETE /v1/lists/{object_type}/{list_slug}/{item_id}. It is categorised as a Destructive tool in the DataMerge MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the DataMerge MCP server in PolicyLayer and add a rule for remove_list_item: 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 DataMerge MCP. Nothing to install.
remove_list_item 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_list_item 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 remove_list_item. 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.
remove_list_item is provided by the DataMerge MCP server (poolside-ventures/datamerge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
remove_list_item is one line of DataMerge's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
