AI agents call remove_team_member to permanently remove resources in Vercel MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a team member is an irreversible operation that permanently revokes their team access and associated permissions. While not data deletion, it is destructive in nature as team membership changes cannot be automatically reversed and require administrative action to restore. Severity is high because misuse could lock out legitimate team members and disrupt project collaboration.
From the tool's definition Tool name 'remove_team_member' with description 'Remove a member from a team' indicates irreversible removal of a user from team membership. This is a destructive action that cannot be trivially undone and alters access controls.

PolicyLayer is an MCP gateway — it sits between your AI agents and Vercel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for remove_team_member:
{
"version": "1",
"default": "deny",
"hide": [
"remove_team_member"
]
}remove_team_member disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
