AI agent calendar
Is there a calendar AI agents can update on their own?
Yes, Squirrel Brain is a calendar and reminder app for iPhone that an AI agent can read and update on its own with a personal API key. The agent can add an event, move it, or cancel it, and each change is labeled with the agent that made it.
You can revoke the key. Server changes are saved right away and reach the phone (and its Calendar) after the app syncs, as an alarm, a reminder, or a phone call. The agent can also read today’s agenda, search notes and calendar events, save a note or a link, send a banner, and file a photo onto a board.
Coming soon to iPhone, and free to use at launch. Get a key at signup, then add Squirrel Brain to any MCP client that can send a custom header. Claude Code, Claude Desktop, and Cursor are examples. See the AI agent calendar, the MCP page, and the developer docs.
