SpamTitan MCP Server

A Model Context Protocol (MCP) server for SpamTitan email security. Enables AI assistants to manage quarantine, maintain allowlists and blocklists, and view email filtering statistics.

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

Features

• Interactive quarantined-message card (MCP Apps, SEP-1865) — spamtitan_get_message renders as a read-only interactive card in MCP Apps hosts (Claude Desktop/web); 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. Rebuild the card bundle with npm run build:ui after editing ui/.
