Add email capabilities to Raycast's AI assistant through MCP. Send and manage email from your system-wide macOS launcher.
Raycast is a productivity launcher for macOS that replaces Spotlight with a powerful, extensible command palette. With built-in AI chat and MCP support, Raycast lets you interact with MultiMail from anywhere on your Mac — press a hotkey, type a prompt, and send an email or check your inbox.
MCP servers in Raycast are configured through the AI settings panel in Raycast's preferences. The setup is straightforward and doesn't require editing config files manually. Once connected, MultiMail tools are available in Raycast's AI chat, accessible from any application via your Raycast hotkey.
This integration excels for quick email actions. Unlike IDE-based integrations where you're focused on coding, Raycast gives you system-wide access to email tools. Draft a quick reply between meetings, check for urgent messages while in another app, or send a follow-up without context-switching to your email client.
Sign up at multimail.dev and create an API key from your dashboard. This key authenticates all MCP server requests.
In the MultiMail dashboard, create a mailbox for Raycast's AI to use. Start with gated_send oversight so all outbound emails require your approval before delivery.
Open Raycast preferences (Cmd+,), navigate to the AI section, and find the MCP Servers configuration. Raycast provides a UI for adding MCP servers.
Add a new MCP server in Raycast's settings with the MultiMail configuration.
Open Raycast's AI chat (invoke Raycast and type 'AI Chat') and ask it to list your mailboxes. If connected, you'll see your MultiMail mailboxes returned.

No code, no dashboard. Paste this to your AI agent — it connects MultiMail, creates an inbox, and builds the flow for you.
Raycast's greatest advantage is system-wide availability. You can invoke MultiMail tools from any application by pressing your Raycast hotkey and opening AI chat. This eliminates the need to switch to a specific app for quick email tasks.
Create Raycast Quick Links that open AI chat with pre-filled prompts for common email tasks. For example, a Quick Link for 'Check my inbox' or 'Send a standup update to [email protected]' saves time on repetitive email operations.
Raycast's clipboard history lets you grab text snippets from any app and include them in emails. Copy important content, invoke Raycast, and ask the AI to email it to the right person — all in a few keystrokes.
Raycast is exclusively available on macOS. If you need similar quick-access email functionality on other platforms, consider Warp Terminal (macOS/Linux) or Claude Desktop (macOS/Windows) as alternatives with MCP support.
