Connect Claude Desktop to XgenPlus Mail
Claude Desktop connects to XgenPlus through the mcp-remote bridge, because its own Add custom connector button needs OAuth sign-in, which XgenPlus does not support yet. Install Node.js, open Settings › Developer › Edit Config, paste the block below with your token, then quit and reopen Claude Desktop. The XgenPlus tools appear in a new chat.
How to connect Claude Desktop
- Create your agent password and make your token.
- Install Node.js (LTS) from nodejs.org if
node --versiondoes not already work in a terminal. - In Claude Desktop, open Settings › Developer and click Edit Config to open
claude_desktop_config.json. - Paste the block below, or merge it into your existing
mcpServers, and replace<TOKEN>with your token. - Quit Claude Desktop fully and open it again.
- Start a new chat and check that the XgenPlus tools appear in the tools or connectors menu.
When to use it
Meera uses Claude Desktop at work. She adds XgenPlus once, and from then on asks Claude to summarise long threads and prepare reply drafts that she sends from webmail.
Configuration
The file is at:
- Windows:
%APPDATA%\Claude\claude_desktop_config.json - Mac:
~/Library/Application Support/Claude/claude_desktop_config.json
{
"mcpServers": {
"xgenplus": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://mcp.xgenplus.com/mcp", "--header", "Authorization:${XGENPLUS_AUTH}"],
"env": { "XGENPLUS_AUTH": "Bearer <TOKEN>" }
}
}
}
Good to know
- Keep
Authorization:${XGENPLUS_AUTH}without a space after the colon. The space goes in theenvvalue, which keeps it working on Windows. - When OAuth support arrives, you will be able to use the connector button instead.
- Claude asks before it uses a tool unless you allow it. Review what it proposes before you approve a send.
Common questions
Why can't I use the Add custom connector button?
That button signs in with OAuth, which XgenPlus does not support yet. It is coming soon. Until then the bridge sends your agent password header instead.
The server shows an error. What should I check?
Check the token, and that npx works in a terminal. Claude Desktop shows server logs in its Developer settings.
