An MCP Tool Returns an Error

A Zinn® Ads tool on the MCP server returned an error? Check the connection's permissions, the safety rules and the sign-in, in exactly this order.

Zinn®, our Viking, reading his checklist beside a measurement rising over time.

Short answer

The Zinn® Ads tools act with your permissions and the dashboard's rules, so an error usually means the connection lacks a permission you did not tick, a safety rule refused the change, or the account needs reconnecting.

Why it happens

An AI assistant can never do more through the MCP server than you can do in the dashboard.

What to do

  1. In the Zinn Digital® dashboard, open AI tools and check what the connection may do.
  2. If a change was refused, read its reason under Needs you or Changes in Zinn® Ads.
  3. If the assistant cannot sign in, connect it again at https://api.zinndigital.com/v1/mcp.
  4. Check each tool's inputs in the developer docs for the MCP server.
