Koskamo

mcp-ecc MCP

A unified Model Context Protocol server that aggregates email, calendar, and contacts from multiple providers (Google, M365, Zoho, IMAP/SMTP, CalDAV, CardDAV) into standardized tools. It allows AI assistants to read, write, and manage these resources uniformly, supporting multi-user setups with self-managed accounts and encrypted credentials.
