Delete one document from a MongoDB collection
AI agents call mongo_delete_one to permanently remove resources in Mcp Database — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The mongo_delete_one tool performs an irreversible deletion of a MongoDB document. Even though it targets only one document, deletion cannot be undone without additional backup/recovery mechanisms outside the tool itself.
From the tool's definition Tool name includes 'delete' and description states 'Delete one document from a MongoDB collection' — this operation irreversibly removes data.
Attacks that exploit this kind of access
Delete one document from a MongoDB collection. It is categorised as a Destructive tool in the Mcp Database MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Database MCP server in PolicyLayer and add a rule for mongo_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 Mcp Database. Nothing to install.
mongo_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 mongo_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 mongo_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.
mongo_delete_one is provided by the Mcp Database MCP server (nam088/mcp-database-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
