Remove a user from a project
AI agents call project_remove_user to permanently remove resources in MongoDB Atlas MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes a user's access to a project, which is a destructive action that alters authentication/authorization state and cannot be automatically reversed. While not data deletion per se, it permanently revokes user permissions and is categorized as Destructive due to its irreversible nature.
From the tool's definition Tool name 'project_remove_user' combined with description 'Remove a user from a project' indicates irreversible deletion of access control. The action 'remove' applied to a user assignment cannot be undone without explicit re-addition by an administrator.
Attacks that exploit this kind of access
Remove a user from a project. It is categorised as a Destructive tool in the MongoDB Atlas MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MongoDB Atlas MCP Server MCP server in PolicyLayer and add a rule for project_remove_user: 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 MongoDB Atlas MCP Server. Nothing to install.
project_remove_user 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 project_remove_user 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 project_remove_user. 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.
project_remove_user is provided by the MongoDB Atlas MCP Server MCP server (montumodi/mongodb-atlas-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
