This one has been quiet for a while

Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

This one needs environment variables set before it will start: VIRWAVE_INLINE (auto (default) shows the session in the chat when the client supports MCP Apps, and opens the browser otherwise. on always answers for the chat view. off never does.), VIRWAVE_SAVE_COPY (Set to true to also save the session page when the session is shown in the chat.), VIRWAVE_OPEN_BROWSER (Used when the session is not shown in the chat. Set to false to stop new sessions opening in the default browser. The file path is returned either way.), VIRWAVE_SAVE_DIR (Folder for session pages. Defaults to a VirWave Breathe folder in the system temp directory.). The author declared them in the registry entry; get the values from the project itself.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

breathe

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.

patterns

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

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.

VirWave Breathe — questions

Answers built from our own checks of this server.

What can VirWave Breathe do?

It exposes 3 tools, read directly from the server on our last check. Among them: breathe, list_patterns, start_session. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is VirWave Breathe working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 272 ms. The bar chart above shows every period we have measured.

Is VirWave Breathe still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect VirWave Breathe?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does VirWave Breathe need an API key?

No. VirWave Breathe completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is VirWave Breathe?

It answers our handshake in 272 ms on average, which is faster than 48% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use VirWave Breathe?

The npm package virwave-breathe was installed 36 times in the last week. Week over week that is -87%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
