Hey developers! Wouldn’t it be cool if your code editor already knew the answers to your project-specific questions? Imagine not having to leave your IDE to look up that one function in your team’s private API documentation.
Refer to our Cusror + CustomGPT.ai’s Hosted MCP server docs for more info.
By connecting CustomGPT.ai to Cursor, the AI-first code editor, you can make this happen.
What’s MCP? (The Simple Version)
Think of the Model Context Protocol (MCP) as a standard plug. It lets your tools, like the Cursor IDE, connect to data sources, like a CustomGPT.ai project full of your documentation. It’s a simple, secure way to make your tools smarter with your own data.
Why use CustomGPT.ai with Cursor?
- Find the right answer: Our system is top-ranked for accuracy, so you can trust the code snippets and explanations it gives you.
- No extra work: We manage the server, the security, and all the boring stuff.
- No extra cost: It’s included in your CustomGPT.ai plan.

How Your Question Finds an Answer
With Cursor, the connection is direct and simple:
You, asking a question in Cursor (`@customgpt-mcp-server`)
│
│ (A direct, secure line over the internet)
▼
┌───────────────────────────────────────────┐
│ CustomGPT.ai Server │
│ (Instantly searches your private docs) │
└───────────────────────────────────────────┘
│
│ (Sends the answer straight back)

The answer appears right in your Cursor IDE!What you’ll need first:
- A CustomGPT.ai account (free trial is fine).
- A project in CustomGPT.ai loaded with your documentation or knowledge base.
- The Cursor IDE.
Let’s Hook It Up: Step-by-Step
- Get your server URL: Log in to CustomGPT.ai. Go to your project’s Deploy ➞ MCP Server (Beta) tab. Generate a token if needed. You’ll see a JSON block; you just need the url from it.
- Open Cursor settings: In Cursor, go to Settings → Cursor Settings → MCP.
- Add your server: Click on + Add new global MCP server.
- Paste the config: Paste this little piece of code, but replace the url with the one you copied from your CustomGPT.ai dashboard.
{
"mcpServers": {
"customgpt-mcp-server": {
"url": "https://mcp.customgpt.ai/projects/<PROJECT_ID>/sse?token=<TOKEN>"
}
}
}- Save and you’re done!
Now, just hit ⌘ K in Cursor and type @customgpt-mcp-server to ask questions. Autocomplete and explanations will now be powered by your own private docs.
Watch it in action:
Your Turn to Build!
So there you have it. No more generic answers! Your favorite AI tool is now your personal expert, with a direct line to the documents and data you care about most. It’s a true game-changer for getting things done.
Why not give it a try? Head over to CustomGPT.ai to start a free trial and create your own private AI brain.
We can’t wait to see what you build with it!
P.S If are into MCP world, you will definitely live this MCP AMA that we did with Pinecone folks and other MCP folks (Santiago).
