Open Connectors

In Claude, open Settings → Connectors and choose Add custom connector.

Name it and paste the URL

Name it Voxmin and paste the MCP server URL:

https://api.voxmin.com/auth/mcp

Keep Authentication on Sign in now, and the OAuth client on Use Claude's published identity. Voxmin supports it, so there is nothing else to fill in. Leave Request headers empty.

Add, then connect

Choose Add, then Connect. Claude opens Voxmin in your browser: log in if you are asked, check that the page names Claude, and choose Approve. You are taken back to Claude.

Make a token

On AI Integrations, make a token. It starts with vxm_ and is shown only once, so copy it then.

Open the config file

In Claude Desktop, open Settings → Developer → Edit Config. That opens claude_desktop_config.json:

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

Add the Voxmin server

Add a voxmin entry under mcpServers (keep any servers already there), with your token in place of <your token>:

{
    "mcpServers": {
        "voxmin": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-remote",
                "https://api.voxmin.com/auth/mcp",
                "--header",
                "Authorization:${VOXMIN_AUTH}"
            ],
            "env": {
                "VOXMIN_AUTH": "Bearer <your token>"
            }
        }
    }
}

The header is written as Authorization:${VOXMIN_AUTH} with no space on purpose: on Windows, Claude Desktop does not escape spaces inside args. The space between Bearer and the token lives in env, where it is safe.

Restart Claude Desktop

Quit Claude Desktop completely and open it again. The config file is only read at start-up.
