@qmailing/mcp-server

Model Context Protocol server for qmailing.

Lets AI agents — Claude Desktop, Cursor, Continue, Zed, anything that speaks MCP — read and modify your qmailing mailboxes, custom domains, and DNS settings on your behalf.

Requirements

• A qmailing account on the PRO tier or higher (the public API is gated on PRO+).
• Node.js 18.17 or later.
• An MCP-compatible client (e.g. Claude Desktop).

Setup

1. Generate an API token

• Sign in at https://qmailing.com.

• Go to Settings → Developers.

• Click New token, give it a label (e.g. "Claude Desktop"), pick the scopes you want the agent to have, and copy the qm_live_… value when it's shown.

  The token only appears once. If you lose it, generate a fresh one.

2. Wire it into your MCP client

The package is published on the public npm registry under the beta tag — npx pulls it on first run, no manual checkout required.

Claude Desktop

Edit claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "qmailing": {
      "command": "npx",
      "args": ["-y", "@qmailing/mcp-server"],
      "env": {
        "QMAILING_API_TOKEN": "qm_live_your_token_here"
      }
    }
  }
}

Pin a specific version (e.g. @qmailing/mcp-server@0.1.0) if you don't want auto-upgrades.

Claude Code

claude mcp add qmailing -- npx -y @qmailing/mcp-server
# Add the env var separately or supply via a wrapper script.

Cursor / Continue / Zed / others

Any MCP client that supports stdio servers takes the same command + args + env shape. Restart the client after editing its config — the qmailing tools appear in the tools menu (the wrench icon in Claude Desktop, similar in others).

Local development checkout

Contributors can run from a checkout instead of npm. Build + point the client at the absolute path:

cd qmailing-web/mcp
npm install
npm run build       # produces dist/server.js

{
  "mcpServers": {
    "qmailing": {
      "command": "node",
      "args": ["/absolute/path/to/qmailing-web/mcp/dist/server.js"],
      "env": { "QMAILING_API_TOKEN": "qm_live_your_token_here" }
    }
  }
}

Security notes

• The token authenticates as your full qmailing account within the scopes you granted. Treat it like a password.
• Tokens are revocable and the FE shows the prefix + last-used timestamp, so you can identify a compromised one and kill it from /settings/developers.
• Plan downgrades disable existing tokens immediately — the API re-checks the plan on every request, no per-token revocation needed.
• The MCP server runs locally on your machine; your token never leaves the process you launched. Only the qmailing API itself sees it.

Development

The package source is maintained in the qmailing monorepo. To work on it locally with a checkout, install deps inside the mcp/ directory and build:

cd mcp
npm install
npm run build
QMAILING_API_TOKEN=qm_live_test_token npm start
