HOW TO CONTROL EBAY_BULK_DELETE_CAMPAIGN_NEGATIVE_KEYWORDS

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

policy.json

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

ebay_bulk_delete_campaign_negative_keywords 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.
