Remove a user from a workspace and revoke workspace access. This does not delete the user from the organization; use delete_user for full removal.
AI agents call remove_workspace_member to permanently remove resources in Portkey Admin — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
| Parameter | Type | Required | Description |
|---|---|---|---|
user_id | string | Yes | The user ID to remove |
workspace_id | string | Yes | The workspace ID |
Parameters from the server's own tool schema.
An AI agent that decides to call remove_workspace_member doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Portkey Admin is gone — there is no undo for destructive operations.
Attacks that exploit this kind of access
Remove a user from a workspace and revoke workspace access. This does not delete the user from the organization; use delete_user for full removal. It is categorised as a Destructive tool in the Portkey Admin MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
remove_workspace_member accepts 2 parameters: user_id, workspace_id. Required: user_id, workspace_id. The full parameter table on this page comes from the server's own tool schema.
Register the Portkey Admin MCP server in PolicyLayer and add a rule for remove_workspace_member: 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 Portkey Admin. Nothing to install.
remove_workspace_member 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_workspace_member 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_workspace_member. 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_workspace_member is provided by the Portkey Admin MCP server (CodesWhat/portkey-admin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
