About smbCloud Mail & Auth
smb is the command-line interface for smbCloud services, intended for developers and AI agents managing email, authentication, projects, and deployments. It also runs as an MCP server, exposing the same operations through one binary.
Key features
- 01Send transactional email
- 02Configure domains and inbox routing
- 03Manage authentication apps
- 04Deploy Rust, Node.js, Ruby, and Swift apps
- 05Run focused mobile and TV automation tools
Use cases
- 01Setting up email domains and routing
- 02Managing an application's authentication setup
- 03Deploying apps from a terminal or CI
- 04Testing mobile and TV apps with automation tools
MCP support
Run `smb --mcp` to expose 31 stdio MCP tools for smbCloud Mail, Auth, projects, and deployments. Authentication uses the token and selected project from `smb login`.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.
https://api.smbcloud.xyz/v1/mcpclaude mcp add --transport http smbcloudxyz-smbcloud-cli https://api.smbcloud.xyz/v1/mcp{"mcpServers":{"smbcloudxyz-smbcloud-cli":{"type":"http","url":"https://api.smbcloud.xyz/v1/mcp"}}}Open in Cursor{"servers":{"smbcloudxyz-smbcloud-cli":{"type":"http","url":"https://api.smbcloud.xyz/v1/mcp"}}}Open in VS Code{"mcpServers":{"smbcloudxyz-smbcloud-cli":{"type":"http","url":"https://api.smbcloud.xyz/v1/mcp"}}}{"mcpServers":{"smbcloudxyz-smbcloud-cli":{"serverUrl":"https://api.smbcloud.xyz/v1/mcp"}}}Run commands in a terminal; paste JSON into the client’s MCP config and restart. Servers that need sign-in will prompt on first connect.

About
smb is the command-line interface for smbCloud. It is
also an MCP server, so Claude, Cursor, and other AI agents can run the same operations
you do.
Send transactional email and set up domains and inbox routing on smbCloud Mail, manage authentication apps on smbCloud Auth, and deploy Rust, Node.js, Ruby, or Swift apps. One binary, no runtime to install.
Install
If you want the quickest setup, use a pre-built native binary.
Homebrew (macOS & Linux)
brew tap smbcloudXYZ/tap && brew trust --tap smbcloudXYZ/tap
brew install cli
npm
npm install -g @smbcloud/cli
.NET tool
dotnet tool install --global SmbCloud.Cli
pip
pip install smbcloud-cli
Shell (macOS / Linux)
curl -fsSL https://raw.githubusercontent.com/smbcloudXYZ/smbcloud-cli/main/install-unix.sh | sh
PowerShell (Windows)
irm https://raw.githubusercontent.com/smbcloudXYZ/smbcloud-cli/main/install-windows.sh | iex
Or grab a pre-built binary from the Releases page.
Quick Start
smb login
smb init
smb deploy
That gets you from login to first deploy.
MCP server
smb --mcp speaks the Model Context Protocol over
stdio, exposing 31 tools across smbCloud Mail, Auth, projects, and deployments. It is
listed in the official MCP Registry as io.github.smbcloudXYZ/smbcloud-cli.
Claude Code:
claude mcp add smbcloud -- smb --mcp
Claude Desktop, Cursor, and anything else that takes a JSON config:
{
"mcpServers": {
"smbcloud": {
"command": "npx",
"args": ["@smbcloud/cli", "--mcp"]
}
}
}
Auth comes from smb login, so a terminal session and an agent session share the same
token and the same selected project. See docs/mcp.md for the full tool
reference.
For mobile and TV app testing, run the focused XCRS Mobile & TV Automation profile:
claude mcp add xcrs -- smb --mcp --scope automation
It exposes target-aware Xcode, ControlKit, CoreDevice, and adb tools without
mixing them into the cloud tool set. The same profile is also available from
the standalone xcrs --mcp crate.
CI / non-interactive mode
Pass --ci (or set SMB_CI=1, or run under any provider that sets CI) to
disable interactive prompts. Confirmations take their default; anything that
truly needs input fails fast with a clear message instead of hanging on a
missing TTY.
smb --ci deploy
For example, the AircraftsHub monorepo deploys
its Next.js web app with a single non-interactive command — its
.smb/config.toml pins the project, source, and runtime, so smb --ci deploy
needs no prompts. See docs/ci.md for token setup and the full
behavior reference.
Documentation
See the docs/ directory for guides on authentication, project configuration, and deployment workflows.

Comments
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
