Remove a managed user from workspace
AI agents call workspace_detach_user to permanently remove resources in Publora MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a user from a workspace typically revokes their access and associations permanently. Without an explicit re-attach or restore mechanism described, this is best classified as Destructive. The blast radius is high because it can cut off user access across multiple social media platform integrations managed by the workspace.
From the tool's definition 'Remove a managed user from workspace' — the action of detaching/removing a user is irreversible without a corresponding re-attach operation, and no undo mechanism is described.
Attacks that exploit this kind of access
Remove a managed user from workspace. It is categorised as a Destructive tool in the Publora MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Publora MCP Server MCP server in PolicyLayer and add a rule for workspace_detach_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 Publora MCP Server. Nothing to install.
workspace_detach_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 workspace_detach_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 workspace_detach_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.
workspace_detach_user is provided by the Publora MCP Server MCP server (publora/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
workspace_detach_user is one line of Publora 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.
