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.

classify
classify_product
Classify a product name into the most likely HSN code via keyword scoring. Returns {best, alternatives[], query, matched_tokens[]}. Best-effort: always returns a result (best may be null if nothing matched).
hsn
search_hsn
Free-text keyword search across HSN descriptions. Returns up to `limit` ranked matches (default 10, max 50). Use this when you have a product name but not a code.
lookup
lookup_hsn
Look up an HSN code (Harmonized System Nomenclature, used by Indian GST). Accepts 4-digit, 6-digit, or 8-digit codes (8-digit gets truncated to 6 then 4). Returns {code, description, gst_rate?}. Throws if no match.

HSN Classifier — questions

Answers built from our own checks of this server.

What can HSN Classifier do?
It exposes 3 tools, read directly from the server on our last check. Among them: classify_product, lookup_hsn, search_hsn. 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 HSN Classifier 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 253 ms. The bar chart above shows every period we have measured.
The registry lists HSN Classifier 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 HSN Classifier?
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 HSN Classifier need an API key?
No. HSN Classifier 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 HSN Classifier?
It answers our handshake in 253 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is HSN Classifier open source?
Yes — it is published under the NOASSERTION licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
