Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (19)
🟢zammad_get_me
The Zammad user this access token belongs to: id, name, e-mail, roles and groups. Use it to confirm the connection and the token's permissions. GET /api/v1/users/me.

}🟢zammad_search_tickets(query, sort_by, order_by, page, per_page)
Search tickets with Zammad's query syntax. With Elasticsearch on the instance you can use fields, e.g. `state.name:open AND group.name:Sales`, `customer.email:"[email protected]"`, `title:invoice`, `number:20001`; a plain word searches ticket text. Replies carry ids plus names (group, state, priority, owner, customer). GET /api/v1/tickets/search?expand=true.

WRITE: change fields of ONE ticket: state, priority, owner (agent), group and/or title. Use names from zammad_list_ticket_states / zammad_list_ticket_priorities / zammad_list_groups. Pending states need `pending_time`. Never deletes, removes or merges (those states are refused). The instance's own triggers still run, so closing or reassigning a ticket can send the customer or agent a notification e-mail. PUT /api/v1/tickets/{id}.
