How to Connect Nuelink's MCP to Your AI Assistant Claude, GPT, Manus, etc.

This guide shows you how to connect Nuelink to your favorite AI assistant (Claude, ChatGPT, Cursor, Manus, Codex, and more) using the Nuelink MCP server. Once connected, you can create, queue, schedule, and draft posts just by talking to your assistant in plain English. The whole setup takes under 2 minutes.


Note: To follow this guide, you'll need a Nuelink account with at least one brand and one collection already set up, plus an AI assistant account that supports MCP (Model Context Protocol). The MCP server is currently in alpha, so some details may change as the product evolves.


Table of Contents



The Nuelink MCP Server lets you publish, schedule, and manage posts from any AI assistant that supports the Model Context Protocol, including Claude, ChatGPT, Cursor, Manus, Codex, and Cline.


Instead of clicking through the dashboard, you just describe what you want:

"Queue this product photo to my Product Launches collection with the caption I just wrote."


The assistant calls the right Nuelink tool for you. Behind the scenes, the MCP server connects to your Nuelink account using your API key and gives the assistant six tools it can use:


  • nuelink_get_me: confirms which account is connected.
  • nuelink_list_brands: lists your brands.
  • nuelink_list_collections: lists collections inside a brand.
  • nuelink_list_channels: lists connected social accounts in a brand.
  • nuelink_upload_file: uploads images or videos to a brand's media library.
  • Nuelink_create_post:  creates a post (queue, schedule, draft, or publish immediately).

Step-by-Step Guide



  1. Log in to your Nuelink dashboard. Go to Settings.

  1. Go to the API tab.

  1. Click Create New Token.

    • Name it, and set an expiration date from 1day up to a year, and hit Generate Token. 

  1. Copy the key right away and store it somewhere safe; you won't be able to view it again after closing the screen. You can directly copy the URL to use with AI tools. Or, directly copy the header.

Important: Treat your API key like a password. Anyone who has it can publish on your behalf. Never share it in screenshots, public chats, or version control.


Step 2: Copy Your MCP URL

The Nuelink MCP server lives at: https://mcp.nuelink.com/mcp 

You can authenticate in one of two ways. Pick whichever your AI assistant supports.


Option 1: API key in the URL (simplest, works with every client)

https://mcp.nuelink.com/mcp?api_key= YOUR_API_KEY

Or use “Copy URL” to copy it directly from Nuelink. 

Option 2: Bearer token in the Authorization header (slightly safer, for clients that support custom headers)

URL: https://mcp.nuelink.com/mcp 

Header: Authorization: Bearer YOUR_API_KEY

Replace YOUR_API_KEY with the key you generated in Step 1 from Nuelink.

You can also copy the header fully from Nuelink.


Pick your assistant below and follow the steps for it.


Claude (web, desktop, mobile)


  1. Open Settings.

  1. Go to Connectors.

  1. Click the “+” sign, then click Add custom connector.

  1. Set Name to Nuelink and Remote MCP server URL to https://mcp.nuelink.com/mcp?api_key= YOUR_API_KEY that was copied from Nuelink. Click Add.

  1. Open the connector and approve the six Nuelink tools.

Claude Desktop (config file)

If you prefer editing the config file directly, add this to claude_desktop_config.json:

{
  "mcpServers": {
    "nuelink": {
      "type": "sse",
      "url": "https://mcp.nuelink.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Restart Claude Desktop after saving the file.

ChatGPT

  1. Open Settings.

  1. Go to Apps.

  1. Go to Advanced settings.

  1. Toggle Developer mode on.

  1. Click Create app.

  1. Set the Name to Nuelink, MCP Server URL to https://mcp.nuelink.com/mcp?api_key=YOUR_API_KEY (that was copied from Nuelink), and Authentication to No authentication (the key is in the URL).

  1. Create and approve.

Cursor

Add this block to ~/.cursor/mcp.json (or your workspace's .cursor/mcp.json):

{
  "mcpServers": {
    "nuelink": {
      "type": "sse",
      "url": "https://mcp.nuelink.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Restart Cursor. The Nuelink tools will appear in the MCP panel.


Manus

  1. Open Settings.

  1. Open Connectors.

  1. Add Connector.

  1. Go to Custom MCP.

  1. Add a custom MCP, then click on Direct configuration.

  1. Set the Name to Nuelink and the URL to https://mcp.nuelink.com/mcp?api_key=YOUR_API_KEY, which was copied from Nuelink.

  1. Save. The six tools will appear in your Manus workspace.

Codex

Add Nuelink to your Codex MCP configuration (typically ~/.codex/mcp.json or via Settings → MCP):

{
  "mcpServers": {
    "nuelink": {
      "type": "sse",
      "url": "https://mcp.nuelink.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Other clients

Any other client that supports remote MCP servers over HTTP works the same way. Point it at https://mcp.nuelink.com/mcp and pass your API key either as the api_key query parameter or as a bearer token in the Authorization header.


Step 4: Verify the Connection

Once you're connected, ask your assistant: "Which Nuelink account am I signed in as?"

The assistant should call nuelink_get_me and reply with your account email and plan. If you see that, you're all set!


Step 5: Create Your First Post

You don't need to memorize any tool names, just describe what you want. Here's the quickest path from zero to a queued post.

  1. See what's available. Ask your assistant: "List my Nuelink brands and the collections in each one." The assistant lists your brands and collections so you can pick where to post.

  1. (Optional) Attach an image. Paste the image directly into the chat, or point the assistant at a local file: "Upload /Users/me/Desktop/launch.jpg to my Fernwood Botanicals brand."
  2. Add it to the queue. Ask the assistant:  "Add this to the queue for my 'Product Launches' collection with the caption 'New season, new scents 🌿 Available Friday.' Use the image I just uploaded." The post lands in the collection's next available time slot, ready to publish to every channel the collection is set up for.

That's it, you're ready to publish, schedule, and draft posts straight from your AI assistant!


Publish modes you can use

The same prompt pattern works for all four publishing modes. Just state what you want:

  • Queue (the recommended default): "Add this to the queue…"
  • Schedule: "Schedule this for Friday at 9 am…"
  • Draft: "Save this as a draft…"
  • Publish immediately: "Post this right now…"

FAQs


Do I need a separate API key for each AI assistant? 

No, you can use the same API key across Claude, ChatGPT, Cursor, Manus, Codex, and any other MCP-compatible assistant. That said, if you want to be able to revoke access for one assistant without affecting the others, you can generate a separate key for each.


Can the MCP post to specific channels only? 

Not directly. The MCP server uses your collection's settings to decide which channels receive a post. If you want a post to go to a different set of channels, post it to a different collection that's set up for those channels.


What time zone are scheduled posts in? 

Scheduled posts use the brand's time zone (set in your Nuelink dashboard), not your computer's local time. If you say "Friday at 9 am," the assistant uses 9 am Friday in whatever time zone that brand is configured for. To be safe, mention the time zone explicitly, for example, "Friday at 9 am Casablanca time."


Can I revoke access if I no longer want an assistant connected to Nuelink? 

Yes. Go to Settings → API in your Nuelink dashboard, find the key you used for that assistant, and click Delete. The next time the assistant tries to call a Nuelink tool with that key, it'll get a 401 Token has 

been revoked response.


Will the MCP work with my team or agency brands? 

Yes. Your API key inherits all the brands your Nuelink user has access to. If you're on a Business or Agency plan, or you've been added to someone else's team, the MCP server sees every brand your key can reach. Just remember, your role applies; if you have read-only access to a brand, you can see it, but can't post to it.


Troubleshooting


I get a "Token is required" (401) error when I try to use a Nuelink tool. 

Your MCP URL is missing both the api_key query parameter and the Authorization header. Double-check that you pasted the full URL with your key, or that the header is set correctly in your config file.


I get a "Token is invalid" or "Token has been revoked" (401) error. 

Your API key was copied incorrectly, deleted, or never existed. Go to Settings → API in your Nuelink dashboard, generate a fresh key, and update it everywhere you used it.


I connected the MCP, but the tools aren't showing up. 

Make sure you have approved the tools in your assistant's permission UI. Some clients (especially Cursor and ChatGPT) need a restart or refresh after the first connection. If you edited a config file, save it and restart the app.


I'm on a team account, but I don't see my agency's brands. 

Your API key inherits your team role. If you have read-only access to a brand in Nuelink, you'll see it through the MCP, but you won't be able to post to it. Ask your admin to upgrade your role.
