ebay_resume_campaign

THE RISK

High Risk

This tool triggers an external operation on eBay's platform — reactivating a paused marketing campaign. It doesn't merely read or write data in isolation; it causes a campaign to actively run again, which can incur advertising spend and affect marketplace visibility. This makes it an Execute-level action.

From the tool's definition Resume a paused marketing campaign. Campaign will start running again.

HOW TO CONTROL EBAY_RESUME_CAMPAIGN

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_resume_campaign:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ebay_resume_campaign": {
      "limits": [
        {
          "counter": "ebay_resume_campaign_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

ebay_resume_campaign stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Ebay — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
