    "name": "removeTeamMember",

## Why removeTeamMember is rated Critical

Removing a team member is a destructive action that revokes access and membership. While the operation is described as idempotent (safe to call multiple times), the act of removing a user from a team is not easily reversible without re-adding them manually, and it can affect collaboration, permissions, and access to resources.

From the tool's own definition: "'Remove a user from a team' — the tool explicitly removes a member from a team, which is a deletion of a membership relationship."

## Use case

AI agents call removeTeamMember to permanently remove resources in Stable Baseline, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Stable Baseline:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "removeTeamMember"
  ]
}
```
