Get detailed information about a specific mailbox including its status, forwarding config, and domain.
AI agents call get_mailbox to retrieve information from TrekMail MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves mailbox metadata and configuration details without creating, modifying, or deleting data. It is a straightforward read operation that performs queries on existing email infrastructure data. The blast radius of misuse is minimal—unauthorized access to mailbox details could expose configuration information but does not enable further malicious actions without separate tools.
From the tool's definition Tool name 'get_mailbox' and description 'Get detailed information about a specific mailbox including its status, forwarding config, and domain' indicate a retrieval operation with no modification or destructive capability.
