Delete a single document from a MongoDB collection (requires FULL mode)
AI agents call mongodb_delete_one to permanently remove resources in Multi-Database MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data from MongoDB. Even though it deletes only one document (rather than many), the deletion is irreversible and constitutes data loss. Destructive operations are more severe than Write operations because they cannot be undone.
From the tool's definition Tool name contains 'delete' and description states 'Delete a single document from a MongoDB collection'. The operation is irreversible—once a document is deleted, it cannot be recovered without backups.
Attacks that exploit this kind of access
Delete a single document from a MongoDB collection (requires FULL mode). It is categorised as a Destructive tool in the Multi-Database MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Multi-Database MCP Server MCP server in PolicyLayer and add a rule for mongodb_delete_one: 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 Multi-Database MCP Server. Nothing to install.
mongodb_delete_one 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 mongodb_delete_one 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 mongodb_delete_one. 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.
mongodb_delete_one is provided by the Multi-Database MCP Server MCP server (nam088/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
mongodb_delete_one is one line of Multi-Database MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
