# Add 1folder to ChatGPT as a connector, so it saves and opens your files

> Add 1folder as a connector and ChatGPT can save its work to your files and open them again in any chat. On the web, open Plugins, press +, choose Add custom MCP server and enter https://1folderapp.com/mcp. Saving works on Business, Enterprise and Edu, where an admin or owner adds it. Pro can add one that only reads; OpenAI doesn’t offer them on Plus, Go or Free.

*Picture: ChatGPT (saves and revises a weekly report) connected to one 1folder holding Weekly report (a page saved by ChatGPT, version 2) and Weekly figures (a table saved by you).* ChatGPT reads your weekly figures and saves a report in the folder you allowed. Future edits update the same report, with a separate version for each save.

## Which ChatGPT plans can add it

- **Business**: Partly. Reads and saves. Only admins and owners add it, then publish it to the workspace
- **Enterprise and Edu**: Partly. Reads and saves. Admins and owners add it, and can let chosen members add one too
- **Pro**: Partly. Reads only: ChatGPT can open your files but can’t save to 1folder
- **Plus, Go and Free**: No. Not offered
- **ChatGPT on the web**: Yes. Where it works, not in the phone app

## Connect ChatGPT to 1folder

1. **Add a custom connection.** On the web, open Plugins, then +, then Add custom MCP server. Name it 1folder and enter https://1folderapp.com/mcp under Connection. Set up sign-in, tick I understand and want to continue, and choose Create as a plugin. If your account still shows Apps, use Apps > Create instead.

   *Picture: Adding 1folder to ChatGPT (Plugins, then +, then Add custom MCP server): the name 1folder and the address https://1folderapp.com/mcp, then Allow in 1folder.*
2. **Sign in.** Follow the app’s prompts to sign in to 1folder with the account holding your work.
3. **Choose the folders and press Allow.** Pick the Reports space or just the folders for this work. Choose View and edit to save files, or View only to review them, then press Allow.

   *Picture: 1folder’s Allow page: “ChatGPT wants to use your 1folder”, with Only the folders I pick in Reports and View and edit chosen, then Allow.*
4. **Check one saved file.** Ask ChatGPT to save Weekly report and return its private link. Open the file and check the actual contents before handing over more work.

   *Picture: In ChatGPT, you type: “Save Weekly report in my 1folder Reports folder and give me its private link.” ChatGPT saves Weekly report (a page saved by ChatGPT, version 1) to 1folder.*

## Requests to try with the connected app

- In ChatGPT: “Read Weekly figures in my 1folder Reports folder. Write Weekly report with the reporting dates, results, uncertainties and next actions. Save it as a page and return its private link.”
- In ChatGPT: “Read the current Weekly report in 1folder. Correct the revenue figure to $18,400 using the source below and update the same file.”
- In ChatGPT: “List the files in my 1folder Reports folder. Tell me which report you read before drafting this week’s update.”

## ChatGPT MCP and custom connectors: what the names mean

A custom connector adds a service to ChatGPT by its address. MCP is the open standard behind that address, which is why OpenAI’s menu says Add custom MCP server. In the current ChatGPT the connector is created as a plugin; accounts on the older layout call it an app.

1folder gives the connected app a place to read and update the files you choose. It doesn’t write the report itself. Connecting doesn’t import old conversations, copy the [ChatGPT Library](https://1folderapp.com/how-to/chatgpt-library.md) or start saving every answer.

## ChatGPT connectors not showing: check these in order

First, check your plan. OpenAI offers custom connectors with reading and saving on Business, Enterprise and Edu, and reading only on Pro. Plus, Go and Free don’t have them. On Business, only admins and owners can add one; members use it once it is published to the workspace. On Enterprise and Edu, an admin can let chosen members add them too.

Next, check the layout and the device. In the current layout, Plugins has a + button with Add custom MCP server, and you don’t need to turn on Developer Mode first. Older layouts use Apps > Create, in workspace settings or your own settings. Custom connectors work in ChatGPT on the web, not in the phone app. OpenAI lists no country limits.

If the option is still missing on a Business, Enterprise or Edu workspace, ask an admin to check the Create plugins with MCPs permission. A 1folder plan can’t turn on a ChatGPT feature. On Plus, Go or Free you can still keep ChatGPT’s work in 1folder: download the [file from ChatGPT](https://1folderapp.com/how-to/where-does-chatgpt-save-files.md) and drag it in, and attach a downloaded 1folder file to a chat when ChatGPT needs to read it.

## A first report that proves the connection works

Put a small table called Weekly figures in Reports: period 2–8 November, revenue $18,400, refunds $620, and two unresolved invoices. Ask ChatGPT to read it and save a Weekly report with those dates and units. Open the returned file and check the figures against your source.

Then change one figure and request an update to the existing report. Versions should show both saved states. That second save tests the ongoing workflow more usefully than a generic “you are connected” reply.

## Control what ChatGPT can change

- Use View only for reading reference material. Choose View and edit for the Reports folder if ChatGPT should save there.
- For future work, add “save my work to 1folder” to your instructions. Check the returned file; instructions are a reminder, not automatic synchronisation.
- Private links require access. Turn on a [public link](https://1folderapp.com/how-to/share-files-with-clients.md) yourself only when the report is ready for anyone with the link to read.
- Remove ChatGPT in 1folder’s Connections to stop access immediately. Previously saved files remain available to you.

## Questions

### How do I add an MCP server to ChatGPT?

On the web, open Plugins, press + and choose Add custom MCP server. Enter a name and the address, set up sign-in, tick the risk notice and choose Create as a plugin. To save files it needs Business, Enterprise or Edu; on Pro it can only read.

### Do I have to enable Developer Mode?

No, not in the current Plugins layout. OpenAI has you review a risk warning for each server you add instead.

### Why are ChatGPT connectors not showing on my work account?

Your role or workspace policy may prevent creation. Ask an admin or owner to check which workspace you are in and the permission to create custom connections.

### Can ChatGPT Plus or Pro save to 1folder?

No. On Pro, a custom connector can only read, so ChatGPT can open your 1folder files but not save to them. Plus, Go and Free can’t add one. On any plan you can download a file from ChatGPT and upload it to 1folder yourself.

### Will ChatGPT save every answer after I connect?

No. Ask it to save the work, then open the link to check it. 1folder does not watch conversations or read your chat history.
