## Tools (3)

- `breathe`: Creates an animated VirWave breathing session the person can follow with their eyes. Invoke it when someone asks for a breathing break, a breathing exercise, guided breathing, or a moment to calm down, relax, or reset: the visual session is the breathing break. In a client that supports MCP Apps (Claude on the web and in the desktop app, for example), the session appears in the chat itself. The result also carries a link to the same session as a web page, for any client that cannot draw it there. Either way the session opens at rest and starts when the person presses Begin, so nothing moves without their say-so. With no inputs, it plays the default Circle 4-8 Breathing session, which has no breath holds.
- `list_patterns`: Lists the VirWave breathing patterns this server can play: phases and seconds, what each rhythm is good for, which shapes can draw it, whether it is hold-free, and any safety note about breath holds. Hold-free patterns are listed first.
- `start_session`: Matches a VirWave session the way the app's entry flow does: how clearly a feeling is coming through, what they'd like instead, and how long they have. Invoke it when someone says how they are feeling, or what they would like to feel instead, and wants a breathing session that fits. The session moves through stages (arrive, the matched core, close), each with its own shape, at one steady breath pace, and ends at the chosen length. In a client that supports MCP Apps (Claude on the web and in the desktop app, for example), the session appears in the chat itself. The result also carries a link to the same session as a web page, for any client that cannot draw it there. Either way the session waits for Begin, and the result says why it was picked and which stages it has. Every matched session is hold-free: breathe in, a longer breath out.
