smbCloud Mail & Auth

smbCloud Mail & Auth runs locally from a Node.js package published to the npm registry: @smbcloud/cli version 0.5.2. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y @smbcloud/cli@0.5.2. It reads the environment variable SMB_MAIL_API_KEY (secret); set it in the client's configuration for this server. Required arguments: --mcp.

smbCloud Mail & Auth runs locally from a .NET package published to NuGet: SmbCloud.Cli version 0.5.2. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs the .NET SDK; run as a .NET tool; the entry names dnx as the runtime. It reads the environment variable SMB_MAIL_API_KEY (secret); set it in the client's configuration for this server. Required arguments: --mcp.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "smbcloud-cli": {
      "command": "npx",
      "args": [
        "-y",
        "@smbcloud/cli@0.5.2"
      ],
      "env": {
        "SMB_MAIL_API_KEY": "<secret>"
      }
    }
  }
}
