Mailbridge MCP

Connect your AI assistant to your email — read, search, send, reply, organise, draft, schedule, and manage attachments from iCloud or any IMAP account. Works with Claude, OpenAI Codex, Cursor, Windsurf, and any MCP-compatible client.

Credentials are stored securely in your OS credential store (macOS Keychain, Windows Credential Manager, or Linux Keyring) — never in a file.
