Meridian 1.56.0

August 9, 2026

Connect an AI assistant to Meridian and let it read — or add to — your tasks and calendar, entirely on your Mac.

Connect an AI assistant to Meridian — Claude, Claude Code, Cursor or anything else that speaks MCP can now work with your consolidated tasks, calendar, contacts and messages. Ask “what’s on today” and get an answer drawn from every account you’ve connected, instead of wiring the assistant up to Google and Microsoft separately.
Let it add things, if you want it to — an assistant can create and complete tasks and put events on your calendar. Reading and writing are separate permissions, so you can grant one and not the other. Nothing can delete your data.
You approve each app by name — the first time a program asks for your data, Meridian tells you which one it is, whether it could verify it, and exactly what it’s asking for. Nothing gets in without you saying yes, and you can revoke any app later from Settings → MCP Clients.
A record of everything that was asked for — every request an assistant makes is listed in the same place, including the ones Meridian refused. That list never leaves your Mac.

It all stays on this Mac — assistants talk to Meridian directly on your machine. No request touches Meridian’s servers, and there’s no key or token to copy around: connecting is one command you can paste anywhere, and Meridian recognises the app itself.
Off until you turn it on — local AI access is a switch in Settings, off by default, and nothing is listening until you flip it.

Encryption keys set up on older versions of Meridian — in some cases a key created before a past update could stop being recognised, which could leave a new Mac unable to finish setup. Meridian now finds and carries those keys forward.
Account settings on the web — the account pages at panel.me.ridian.app couldn’t reach Meridian and wouldn’t load. They work again.
