Overview

AI-generated overview

Lets an assistant start calm, animated breathing sessions paced to the user's breath, shown in chat or opened in a browser.

What you can do
VirWave Breathe provides animated breathing sessions paced to the user's breath. Sessions can be displayed inside the chat when the client supports MCP Apps, or opened in the default browser instead. The session page can also be saved to a folder, and the file path is returned either way.
When to use it
Useful when someone wants a guided breathing or relaxation break started from an assistant conversation, either inline in the chat or in a browser window.
Requirements
Runs as a remote endpoint or as a local npm package started with npx, so Node.js is needed for the local option. Optional environment variables control behavior: VIRWAVE_INLINE, VIRWAVE_OPEN_BROWSER, VIRWAVE_SAVE_COPY and VIRWAVE_SAVE_DIR. No authentication is declared.
Before you install
The server states it runs locally and collects nothing. Setting VIRWAVE_SAVE_COPY writes session pages to disk, and VIRWAVE_SAVE_DIR chooses that folder; VIRWAVE_OPEN_BROWSER controls whether a browser window opens. No credentials or payments are requested.

Installation

In SourceWeft

  1. Open VirWave Breathe in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.virwave%2Fvirwave-breathe/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

list_patterns

List breathing 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.

Takes no parameters.

breathe

Start a breathing session

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.

start_session

Start a matched 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.
