THE RISK

Critical Risk

Why remove_project_member needs a policy

Removing a project member revokes their access and project association. While not data deletion, membership removal is typically not easily undone (the member must be re-invited/re-added), making it closest to Destructive. The blast radius is high as it can cut off a user's access to a project, potentially disrupting workflows.

From the tool's definition 'Remove a member from a specific project' — removing membership is an irreversible or hard-to-reverse action that revokes access

POLICY

How to control remove_project_member

PolicyLayer is an MCP gateway — it sits between your AI agents and eToro MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for remove_project_member:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "remove_project_member"
  ]
}

remove_project_member disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
