​
Connecting to the Server

The Nexudus MCP server is a hosted service. You do not install anything locally — you point your MCP client at the server URL and log in with your Nexudus account.

​
Server URL

https://mcp.nexudus.com
This is the only address you need. All client setup pages start by entering this URL.

​
Prerequisites

  • A Nexudus account with the permissions you want the AI assistant to use. The server only sees data your account can see.
  • An MCP-capable client — Claude.ai, ChatGPT, Claude Desktop, Claude Code, or VS Code with GitHub Copilot. See Supported clients below.
  • A web browser for the one-time login. The first connection opens a browser window where you enter your Nexudus email and password.

​
Supported clients

The Nexudus MCP server has been tested with the following clients. Each has its own setup steps:

Claude.ai

Web chat at claude.ai.

ChatGPT

Web chat at chatgpt.com.

Claude Desktop

Anthropic’s desktop app.

Claude Code

Anthropic’s terminal-based AI assistant.

VS Code (GitHub Copilot)

GitHub Copilot’s MCP extension.

​
Technical requirements (for other clients)

If your client is not in the list above, it can still connect provided it supports:
  • OAuth 2.0 Authorization Code Flow — used to log in with your Nexudus credentials.
  • Streamable HTTP Transport — used by the client to send requests.
  • Tools — the operations exposed by the server (tools/list, tools/call).
Optional but recommended: MCP Resources support. This lets clients fetch documentation directly without using a tool call. Support is uneven across off-the-shelf clients — the Nexudus MCP server falls back to tool-based documentation when resources are not supported.

​
What happens the first time you connect

  1. You add https://mcp.nexudus.com to your MCP client.
  2. The client opens a browser window with the Nexudus login page.
  3. You enter your Nexudus email and password.
  4. The client receives an access token and stores it.
  5. Your AI assistant now has Nexudus tools available.
Your Nexudus password is never stored by the MCP server. It is used once to verify your identity, and the server keeps only a short-lived access token tied to your session.
Sessions last 8 hours. After that, your assistant will tell you the connection has expired and you can reconnect using the same steps. See Sessions and re-authentication for details.
