Give an agent every mailbox you own, under permissions you control
Grounded in available product and source data
Sickle runs a remote MCP server that hands every mailbox you own to Claude, Claude Code, Cursor, Codex or any other MCP client. Gmail and Outlook connect through OAuth, and iCloud, Fastmail, Yahoo or any IMAP server can join at the same time.
Twelve tools cover listing, searching, reading, marking, moving, trashing, drafting and sending. Permissions split into read, change and send scopes that you can revoke per client, and clients ask before each send. It runs on macOS, Windows or Linux with nothing to install.
