Mimecast

Connects Claude to your Mimecast email security environment through their API. You get access to message tracking, held message queues, domain management, and threat intelligence data. Built by Wyre Technology as part of their MSP-focused Claude plugin ecosystem. Requires Mimecast API credentials (client ID, secret, and region). Useful if you're managing email security for multiple clients and want to investigate suspicious messages, clear quarantine queues, or pull threat intel without switching between dashboards. Ships as an npm package with Docker support and works over stdio transport.
