Google Ads API Account Performance Diagnostics Skill

This skill provides instructions on how to use the Google Ads MCP server tools to diagnose common account performance issues.

Workflows

Pre-Flight Tool Verification

Before starting any diagnostic task, verify whether the Google Ads MCP Server tools (search, list_accessible_customers, get_resource_metadata — these may be exposed with a server prefix, e.g. customers_list_accessible_customers) are available in the runtime environment:

• If MCP tools are available: Proceed with live diagnostics — first identify active client accounts, then run GAQL via the search tool (arguments customer_id and query).
• If MCP tools are missing: Follow Fallback When MCP Tools Are Unavailable.

Identifying Active Client Accounts

Most diagnostics tasks require sending GAQL queries to a specific customer account. If the customer ID is not explicitly provided by the user, you must first call the list_accessible_customers (or customers_list_accessible_customers) tool to retrieve the customer resource names/IDs you have access to.
