Configure

You need a DocNexus account. Sign-in uses OAuth 2.0 with PKCE; your client opens a browser window the first time you connect.

GitHub Copilot (VS Code)

Add to .vscode/mcp.json:

{
  "servers": {
    "docnexus": {
      "type": "http",
      "url": "https://mcp.docnexus.ai/mcp"
    }
  }
}

Start the server from the MCP view and sign in when prompted.
