Local-first agent runtime for Windows

AI that can operate the work surface.

One engine, four surfaces. PeriCode CLI runs the agent in your terminal. PeriCode Inside embeds it in Obsidian (VS Code and Cursor next). PeriCode Sidecar attaches to apps without a plugin model. Periphery exposes the same desktop engine through MCP for Claude, Cursor, Windsurf, and any MCP client.

claude> what apps are open on monitor 1 right now?
tool mcp__periphery__list_window_topology
{ windows: 7, monitor_1: ["Cursor", "Edge", "Slack"], monitor_2: ["Obsidian"] }
Cursor and Edge share monitor 1 side-by-side. Slack is hidden behind Edge. Obsidian is fullscreen on monitor 2.
 
claude> tile cursor + edge horizontally, move slack to monitor 3

Same engine. Same policy gate. Same audit trail — whichever surface you run it from.
PeriCode CLI — standalone Windows terminal. Embedded desktop engine. The main thing you run directly.
