# Claude connectors: add 1folder so Claude saves and opens your files > Add 1folder as a custom connector and Claude can save its work to your files and update them later, in the folders you choose. In Claude, open Customize, then Connectors. Choose Add, then Custom and Web, and enter https://1folderapp.com/mcp. Sign in to 1folder and press Allow. Every Claude plan can add custom connectors; Free allows one. *Picture: Claude (saves your drafts and updates them when you ask) connected to one 1folder holding Studio proposal (a page saved by Claude, version 2) and Client feedback (a page saved by you).* Claude connected to a folder in your 1folder: it saved the Studio proposal and, after your client’s feedback, version 2 of it. You choose which folders it sees. ## Which Claude plans can add it - **Free**: Partly. One custom connector - **Pro, Max and Ultra**: Yes. Available - **Team and Enterprise**: Partly. Once an owner turns connectors on for the organisation - **Claude on the web and desktop**: Yes. Where you add it - **Claude on iPhone and Android**: Partly. Adding one there is in beta; one added on the web shows up on your phone next time you sign in Checked on November 11, 2026, from Claude’s help page on connectors (sources below). ## Add 1folder to Claude 1. **Add a custom connector.** In Claude, open Customize, then Connectors. Choose Add, then Custom and Web. Enter 1folder as the name and https://1folderapp.com/mcp as the address. *Picture: Adding 1folder to Claude (Customize, then Connectors, then Add, then Custom, then Web): the name 1folder and the address https://1folderapp.com/mcp, then Allow in 1folder.* 2. **Sign in, and finish adding it.** Claude checks the address and shows the sign-in it found. Leave it as it is, choose to sign in and finish adding the connector. Claude sends you to 1folder. 3. **Choose what Claude can see, then Allow.** Sign in to 1folder. Pick a space, then everything in it or only the folders you choose. Choose View and edit if Claude should save work, or View only for research. Press Allow. *Picture: 1folder’s Allow page: “Claude wants to use your 1folder”, with Only the folders I pick in Work and View and edit chosen, then Allow.* 4. **Ask Claude to save something.** Ask Claude to save a first draft and give you its link. Open it in 1folder and check it before you use the connection for more. *Picture: In Claude, you type: “Save this proposal as Studio proposal in my Client drafts folder in 1folder.” Claude saves Studio proposal (a page saved by Claude, just now) to 1folder.* ## What to ask Claude once it’s connected - In Claude: “Save this proposal as Studio proposal in my 1folder Client drafts folder. Give me the private link.” - In Claude: “Read Studio proposal in 1folder. Apply the client feedback below and save a new version of the same file.” - In Claude: “Make a one-page site for the proposal and save it to 1folder as one HTML file.” - In Claude: “What’s in my Client drafts folder in 1folder? List each file with when it last changed.” ## What a Claude connector is A connector lets Claude use another service while you chat: read from it, and save to it when you ask. Claude has a Connectors Directory of ready-made ones, and custom connectors you add yourself with a name and an address. 1folder is a custom connector. Its address, https://1folderapp.com/mcp, is a [remote MCP server](https://1folderapp.com/compare/claude-connectors-vs-mcp.md): MCP is the open standard Claude uses to connect to services like this. You don’t need to know anything about it to add one; it is a name, an address and a sign-in. Once it’s added, Claude can save what it makes, such as drafts, tables, web pages and files, to the folders you allowed, and read them again in a later chat. Another AI app [connected to the same folder](https://1folderapp.com/integrations/use-chatgpt-and-claude-together.md) can open the same files. ## Start with one draft Don’t move all your work at once. Save one proposal in a Client drafts folder, then ask Claude to update that file after feedback. The earlier version is kept, with Claude’s name on the change, and the conversation stays where it is in Claude. ## Keep it under your control - Ask Claude to save the actual work as a page, table or file. 1folder doesn’t read the conversation or bring over its memory. - Give a research-only connection View only. Give a drafting connection View and edit on the folders it needs, and leave other work outside it. - Every change is a version showing which app made it. Compare versions, and undo one file’s change or everything an app did in one go. - A private file link needs access and a sign-in. Only you can turn on a [public link](https://1folderapp.com/how-to/share-files-with-clients.md); Claude can’t publish a file for you. ## Questions ### Is a Claude custom connector the same as an MCP server? A custom connector is how you add a remote MCP server to Claude. You give Claude the server’s address, https://1folderapp.com/mcp for 1folder, and sign in; Claude does the rest. ### Do I need Claude Pro to add 1folder? No. Claude’s help page includes Free, with a limit of one custom connector. If you already use that one, check Claude’s plans before you change your subscription. ### Does Claude save everything after connecting? No. Connecting only gives Claude the option. Ask it to save, or add “save my work to 1folder” to your instructions so you don’t have to ask each time. Either way, open the link it returns. ### Can I use it in the Claude app on my phone? Yes. Add it on the web or in Claude Desktop, and it shows up in the phone app the next time you sign in there. Saved files open in your phone’s browser too. ### How do I stop Claude using 1folder? Remove its connection in 1folder’s Connections. Access stops at once, and your saved files stay where they are. ## Sources - [Claude Help Center: Use connectors to extend Claude’s capabilities](https://support.claude.com/en/articles/11176164-use-connectors-to-extend-claude-s-capabilities) Checked on November 11, 2026. ## Read next - [Claude connectors vs MCP: the feature and the standard](https://1folderapp.com/compare/claude-connectors-vs-mcp.md): Claude connectors are the connections you add; MCP is the open standard behind custom ones.
