Liquid Composer does not always answer

Over the last week it answered 20.3% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

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.

liquid
liquid_open
Turn a recipe into a link that opens the icon in Liquid Composer. The link carries the recipe in its URL fragment, so opening it does not send the recipe to a server. Images must be inline SVG markup or data: URLs.
liquid_schema
JSON Schema of recipes and layer patches, and the guide.
liquid_validate
Check a recipe without opening it; returns ok or the list of issues with their paths.

Liquid Composer — questions

Answers built from our own checks of this server.

What can Liquid Composer do?
It exposes 3 tools, read directly from the server on our last check. Among them: liquid_open, liquid_schema, liquid_validate. 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 Liquid Composer working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 6 of 91 checks got a reply (6.6%), average response time 726 ms. The bar chart above shows every period we have measured.
The registry lists Liquid Composer as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Liquid Composer?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Liquid Composer need an API key?
No. Liquid Composer 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 Liquid Composer?
It answers our handshake in 726 ms on average, which is faster than 11% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Liquid Composer open source?
The code is open source: it is published under the MIT licence, written in TypeScript, 65 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at liquid-composer.vercel.app, which runs on its operator's own terms.
