Mimecast MCP Server

A Model Context Protocol (MCP) server for Mimecast email security. Enables AI assistants to track messages, investigate threats, manage email queues, and access threat intelligence data.

This is a Model Context Protocol (MCP) server that connects Claude (or any MCP-compatible AI) to your Mimecast environment.

Part of the MSP Claude Plugins ecosystem — a growing suite of AI integrations for the MSP stack. Built by MSPs, for MSPs.

Interactive Message Card (MCP Apps)

mimecast_get_message_info renders as an interactive, read-only card in MCP Apps hosts (Claude Desktop/web) showing delivery status, sender/recipients, spam score, and rejection details; plain-JSON behavior is unchanged in other hosts. The card is neutral by default, brandable via window.__BRAND__ injection or MCP_BRAND_* env vars (MCP_BRAND_NAME, MCP_BRAND_LOGO_URL, MCP_BRAND_PRIMARY_COLOR, MCP_BRAND_ACCENT_COLOR, MCP_BRAND_BG, MCP_BRAND_TEXT) — no rebuild needed.
