This commit enables the tool to accept an optional parameter. This is required when accessing client accounts via a Manager Account, as the Google Ads API demands the header in such cases. Changes: - Updated to dynamically create/retrieve a GoogleAdsClient with the specific if provided. - Updated to accept the argument and pass it to the service factory. - Added tool documentation hints.

Hi, thanks for looking into this! We are evaluating adding this feature in a future version of the MCP server, but we won't be doing so right now. Thanks. |

This PR adds support for the login_customer_id parameter in the search tool. This is critical for users accessing Client Accounts via a Manager Account, as the Google Ads API explicitly requires the login-customer-id header to be set for these requests.
Problem
Currently, attempting to query a client account (customer_id) while authenticated as a Manager Account results in a USER_PERMISSION_DENIED error with the message to pass a login_customer_id as part of the headers. This happens because the default client initialization uses the global configuration without the specific login-customer-id context required for hierarchy traversal. The MCPs do not currently support passing this information and this PR adds this functionality.
