Cursor MCP: add 1folder so Cursor saves and reads your files

Connect Cursor to 1folder

1. 1

   Add the remote server configuration

   In your project, merge this entry into .cursor/mcp.json, preserving any servers already there: { "mcpServers": { "1folder": { "url": "https://1folderapp.com/mcp" } } } For access across projects, use ~/.cursor/mcp.json instead.

   Cursor

   {
     "mcpServers": {
       "1folder": {
         "url": "https://1folderapp.com/mcp"
       }
     }
   }

   Then sign in to 1folder and pressAllow

2. 2

   Complete the sign-in in Cursor

   Open Customize and find the 1folder server. Follow its authentication prompt to sign in to 1folder. Cursor supports browser sign-in for remote HTTP servers.

3. 3

   Choose the folders and press Allow

   Pick the Product space or just the folders for this work. Choose View and edit to save files, or View only to review them, then press Allow.

4. 4

   Check one saved file

   Ask Cursor to save Search implementation and return its private link. Open the file and check the actual contents before handing over more work.

   Cursor

   Save Search implementation in my 1folder Product folder and give me its private link.

Requests to try with the connected app

• In CursorCopy

  “Read Search acceptance criteria in my 1folder Product folder. Compare them with the current search UI and list gaps before editing.”

• In CursorCopy

  “Save Search implementation in 1folder: files changed, code revision, keyboard behaviour, empty state, checks actually run and unresolved questions. Return its private link.”

• In CursorCopy

  “Read the current Search implementation page and update the same file with the accessibility findings below. Keep unresolved issues clearly marked.”

Cursor MCP servers: local commands and remote addresses

Choose where to put the Cursor MCP setup

Add a remote MCP server to Cursor without replacing other entries

Verify a feature brief rather than a generic test

If the remote connection is present but not useful

• Check the configuration path and JSON first. An entry in one project’s .cursor/mcp.json doesn’t load in other projects.
• Finish the server’s sign-in and Allow page. A registered address is not the same as access to your 1folder files.
• Check the permitted folder and editing level. View only can support review but cannot save implementation notes.
• Ask Cursor explicitly to read the current file before updating it. 1folder does not automatically copy local files or synchronise repositories.
• Use View only for a second app reviewing the brief. Give it editing access only if it should change the saved work.

Questions

What JSON adds a Cursor remote MCP connection?

Use { "mcpServers": { "1folder": { "url": "https://1folderapp.com/mcp" } } }. Merge that entry into your existing configuration rather than discarding other servers.

Should I use .cursor/mcp.json or ~/.cursor/mcp.json?

Cursor documents the first as project configuration and the second as your global configuration. Choose according to where you want the tool available.

Do I need a command to start the 1folder server?

No. 1folder runs at its remote address. Cursor’s command-based examples are for local servers, a different setup.

Can Cursor and Claude Code work from the same brief?

Yes. Connect Claude Code and Cursor to the same 1folder folder and ask each to read the latest saved brief. Coordinate source changes with Git and your normal development workflow.

Can I undo Cursor’s work?

In 1folder you can compare and undo its saved file changes. That does not undo edits in your local repository; use Git for those.
