OpenPrefs

Set up OpenPrefs in Claude

OpenPrefs is in Claude’s connector directory. You connect it once and approve what Claude can use; no token needed.

Open OpenPrefs in Claude

Steps

  1. Create a free OpenPrefs account at openprefs.ai/signup, or sign in if you have one.
  2. Connect it in Claude. Open OpenPrefs in the Claude directory and connect it.
  3. Approve it in OpenPrefs. Claude sends you to OpenPrefs, where you sign in and see Connect Claude? Choose the spaces it can use, and whether it can only read them or also make changes, then select Connect. A new app starts with no access, so pick at least one space.
  4. Back in Claude, start a new chat. If Claude doesn’t use OpenPrefs, check that it’s turned on in the chat’s tools menu.

Adding it yourself

You can also add OpenPrefs in Claude’s settings as a custom connector, with this address:

https://mcp.openprefs.ai

Try it

Ask Claude something that needs your preferences, or tell it something worth keeping:

  • “What do my OpenPrefs say about where I like to eat?”
  • “Save to OpenPrefs that I like Italian food and prefer dinner after 6pm.”

Every read and change shows on your Activity page, and you can undo any change. To change what Claude can use, or disconnect it, open the Agents page.
