Feature Request: Read-capable API for AI assistant integration
-
I’m a long-time Premium subscriber with 4 active journals with tons of photos and more than 3000 entries. The new Zapier integration is a welcome step, but it only covers write access.
What’s missing is read access, the ability for AI assistants like Claude to query journal entries. The use case is simple: “Find entries where I was working through a creative block.” Right now that’s impossible without a manual export.
A read-capable API would make Day One a living, queryable knowledge base not just a write-only archive. AI connector frameworks like Anthropic’s MCP are ready and waiting. Day One would be one of the most meaningful integrations possible.
Please consider this a separate and distinct request from write automation. The value is entirely different.

I have some good news: Day One already has a local MCP Server feature on Mac. You can enable it in the Mac app under Settings > Labs (“Mac CLI MCP Server”), then launch it from Terminal using the “dayone mcp” command. Once it is running, AI assistants like Claude can connect to it and query your journal entries directly. Because it runs locally on your Mac, your data never leaves your device.
The full setup guide is here: https://dayoneapp.com/guides/day-one-for-mac/day-one-mcp-server/

Oh wow that’s a great news. I read it but I am not that savvy with terminal and those stuff, but I will ask a friend to do it for me. I assume that we can link all the journals we have and not just one, right?

Yes, you can link multiple journals. The MCP Access Control settings let you enable access per journal individually, so you can give your AI assistant access to as many of your journals as you like.
With the Day One MCP Server you can search entries by keyword, date range, or specific journal, and use AI assistants like Claude Desktop to query your journals in exactly the way you described.

Thank you, I finally was able to set it up with the help of a knoledable friend.
Thank you. I hope in the future you will make it a public Api so can be use even on the iphone.

Well, it worked for few days and then this happened.
Not sure if the screenshot is visible. it says that the connection to dayone failed.

Hello, so I figured out that Day One needs to be open on my mac in order for me to work from Claude, ask to search and or to write for me etc.
So it looks is working.
