Find and install the MultiMail MCP server through Smithery's registry. One-command setup for email tools in any MCP client.
Smithery is an MCP server registry and hosting platform that makes it easy to discover, install, and manage MCP servers. The MultiMail MCP server is available on Smithery, enabling one-command installation and automatic configuration for any compatible MCP client.
Instead of manually writing configuration JSON, Smithery can generate the correct config for your specific MCP client. Search for MultiMail on Smithery, select your client (Cursor, Claude Desktop, VS Code, etc.), and get a ready-to-use configuration with the right format and paths.
Smithery also provides hosted MCP servers, usage analytics, and version management. For teams deploying MultiMail across multiple developers, Smithery streamlines the onboarding process and ensures everyone uses the same server configuration.
Sign up at multimail.dev and create an API key from your dashboard. This key authenticates all MCP server requests.
Visit smithery.ai and search for 'MultiMail' or '@multimail/mcp-server'. The MultiMail server listing shows available tools, configuration options, and compatible clients.
Use the Smithery CLI to install MultiMail with a single command. This automatically configures the server for your default MCP client.
npx -y @smithery/cli install @multimail/mcp-server --client cursorDuring installation, Smithery will prompt for your MultiMail API key. Enter your mm_live_ key to authenticate the server connection.
Open your MCP client and ask the AI to list your MultiMail mailboxes. Smithery handles the configuration, so the server should be ready to use immediately.

Smithery's one-command install simplifies onboarding new team members. Share the install command with your team, and each member only needs to provide their own MultiMail API key. No manual config file editing required.
Smithery can host MCP servers so you don't need Node.js installed locally. This is useful for environments where installing Node.js is impractical or for clients that prefer SSE transport over stdio.
Smithery tracks server versions and compatibility. When updating MultiMail or your MCP client, check Smithery's listing for any compatibility notes or breaking changes between versions.
Smithery generates configuration for many MCP clients. Specify your client with the --client flag during installation, and Smithery writes the config to the correct path in the correct format. Supported clients include Cursor, Claude Desktop, Cline, and more.
