This guide will help you set up Cursor to help you build custom Agent User Interaction Protocol (AG-UI) servers and clients faster. The same principles apply to other IDE’s like Windsurf, VSCode, etc.

​
Adding the documentation to Cursor

  1. Open up the Cursor settings
  2. Go to Features > Docs and click ”+ Add new Doc”
  3. Paste in the following URL: https://docs.ag-ui.com/llms-full.txt
  4. Click “Add”

​
Using the documentation

Now you can use the documentation to help you build your AG-UI project. Load the docs into the current prompt by typing the @ symbol, selecting “Docs” and then selecting “Agent User Interaction Protocol” from the list. Happy coding!

​
Best practices

When building AG-UI servers with Cursor:
  • Break down complex problems into smaller steps
  • Have a look at what the agent was doing by checking which files it edited (above the chat input)
  • Let the agent write unit tests to verify your implementation
  • Follow AG-UI protocol specifications carefully
