Nothing serious here today

Today is the operative word: we check Swatch Ledger every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 2

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

measure
measure_fabric_shrinkage
Calculates fabric shrinkage (or growth) from a swatch measured before and after washing and drying: length change along the selvedge, width change across the fabric, and the change in area. Use the same marked distances before and after, in one unit (cm or inches). Positive percentages are shrinkage, negative are growth.
plan
plan_fabric_length
Works out how much fabric to buy before washing so that the usable length needed remains afterwards: required length = (usable length + extra) ÷ (1 − lengthwise shrinkage), then rounded up to the shop’s selling increment. Works in metres or yards (any one unit). A negative shrinkage rate means growth.

Swatch Ledger — questions

Answers built from our own checks of this server.

What can Swatch Ledger do?
It exposes 2 tools, read directly from the server on our last check. Among them: measure_fabric_shrinkage, plan_fabric_length. 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 Swatch Ledger working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 37 ms. The bar chart above shows every period we have measured.
How do I connect Swatch Ledger?
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 Swatch Ledger need an API key?
No. Swatch Ledger completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Swatch Ledger?
It answers our handshake in 37 ms on average, which is faster than 99% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
