The server uses HTTP Basic authentication with Mailchimp's API:

- Waits when limit is reached
- Resumes after reset time

Scored across 120 tools
The set contains multiple exact-purpose duplicates, such as mailchimp_lists_batch_subscribe vs mailchimp_audiences_batch_subscribe, mailchimp_lists_get_growth_history vs mailchimp_audiences_get_growth_history, and mailchimp_lists_get_segments vs mailchimp_audiences_get_segments. Members_delete and members_archive also have nearly identical descriptions, making tool selection highly ambiguous.
Most tools follow a mailchimp_<domain>_<resource>_<action> pattern and are consistently snake_case, but there are notable deviations: search_campaigns and search_members invert the verb placement, and lists/audiences are used interchangeably for the same underlying resource. Members_add_tags is also misnamed since it handles both adding and removing tags.
120 tools is far beyond the 50+ extreme threshold and creates an enormous navigation burden. Even with Mailchimp's broad API surface, the count is excessive and includes many redundant or near-duplicate tools.
Core areas like campaigns, lists, members, templates, landing pages, and ecommerce CRUD are well covered, but there are notable gaps: promo rules only have list, promo codes only have list/add, and automations lack update/delete lifecycle operations. These gaps require agents to work around missing functionality.
