Google Ads Transparency Center

API and webhooks

There is no clearly public API for the site. Google's help text mentions API access to EEA ad data, which may be limited to regulators. Until that is clear, treat it as a manual research tool, and put the findings in a shared doc or in Notion so the team can reuse them.

MCP server

There is no official MCP server for it. An agent can still help if you paste in what you found. Ask an assistant such as Claude to group a competitor's ads by message and spot the claims they repeat.
