Overview

The Pieces Desktop app is designed to act as a hub for the Pieces Suite, powered by PiecesOS and the Long-Term Memory (LTM-2.7) Engine.

With the Pieces Desktop App, you have access to dedicated views for the context captured by Long-Term Memory through Pieces Timeline.

Activity Timeline

A horizontal activity timeline at the bottom of the main view shows your workflow activity across the day (from 12am to 12am). Hover over any point to see a tooltip with more details—including the timestamp, memory count, and LTM status (e.g., ON LTM-2.7, ON LTM Audio) for that moment.

Pieces Timeline

Keep track of your workflow so you can access stored context from yesterday, last week, or even last month—whenever you need it. The Long-Term Memory (LTM-2.7) Engine ensures that nothing slips through the cracks.

Pieces Timeline provides a sleek UI for interacting with saved data from up to 9 months ago in an easily digestible format, allowing you to view timeline events, workstream summaries, single-click summaries, and conversational searches.

Explore all configuration options to customize your Pieces Desktop experience.

Model Context Protocol (MCP) Support

The Pieces suite, powered by the LTM-2.7 Engine through PiecesOS, also provides support for Model Context Protocol (MCP) servers through Server-Sent Events (SSEs).

With the Pieces MCP, you can thread rich workflow context through to Cursor, GitHub Copilot, Goose, and other IDEs and productivity tools, making Pieces a platform for using long-term context in other workflows outside of just the Pieces Desktop App.

To integrate the Pieces MCP into one of the available integrations, copy the SSE endpoint URL and/or `.json` schema into your IDE of choice.

You can find the MCP URL inside the Model Context Protocol (MCP) tab within Settings.
