Capabilities

Tools

18 tools
mailchimp_add_member
Add member
Add a new member (subscriber) to an audience (list). Note: status "pending" triggers a double-opt-in confirmation email. REST: POST /lists/{list_id}/members.
Destructive
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'required': ['list_id', 'email_address'], 'properties': {'tags': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Array of tag-name strings to apply to the new member.'}, 'status': {'enum': ['subscribed', 'pending', 'unsubscribed', 'cleaned'], 'type': 'string', 'description': 'Subscription status (default "subscribed"; "pending" sends a double-opt-in email).'}, 'list_id': {'type': 'string', 'description': 'The audience (list) id to add the member to.'}, 'merge_fields': {'type': 'object', 'description': 'Merge-field values, e.g. { FNAME: "Ada", LNAME: "Lovelace" }.', 'propertyNames': {'type': 'string'}, 'additionalProperties': {}}, 'email_address': {'type': 'string', 'description': "The member's email address (required)."}}}
mailchimp_add_member_tags
Add/remove member tags
Add and/or remove tags on an audience member (by email or subscriber_hash). `tags` are added (status active); `removeTags` are removed (status inactive). Mailchimp returns HTTP 204 (no body). REST: POST /lists/{list_id}/members/{subscriber_hash}/tags (email → MD5 hash).
Destructive
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'required': ['list_id'], 'properties': {'tags': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Tag names to ADD to the member (mapped to status "active").'}, 'email': {'type': 'string', 'description': 'Member email address — MD5-hashed (lowercased) into the subscriber_hash for you.'}, 'list_id': {'type': 'string', 'description': 'The audience (list) id.'}, 'removeTags': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Tag names to REMOVE from the member (mapped to status "inactive").'}, 'subscriberHash': {'type': 'string', 'description': 'The subscriber_hash (MD5 of lowercased email) or contact id, if you have it instead of `email`.'}}}
mailchimp_archive_member
Archive member
Archive (soft-remove) an audience member — reversible; this is NOT the permanent-delete action. REST: DELETE /lists/{list_id}/members/{subscriber_hash} (email → MD5 hash). Returns HTTP 204 (no body).
Destructive
