Setting Environment Variables

In MCP Configuration

{
  "mcpServers": {
    "nexus": {
      "command": "nexus",
      "args": ["serve"],
      "env": {
        "NEXUS_VERBOSE": "true"
      }
    }
  }
}

System-wide

macOS/Linux:

export NEXUS_VERBOSE=true

Windows:

$env:NEXUS_VERBOSE = "true"

Authentication Token

For automated workflows, you can set an auth token instead of using interactive login:

export NEXUS_AUTH_TOKEN="your-token-here"

Get your token from the Nexus dashboard or by running nexus auth token.
