HSN Classifier

https://hsn-classifier-mcp.atlasword.workers.dev/mcp ↗

HSN Classifier is a remote MCP server published at hsn-classifier-mcp.atlasword.workers.dev. It has been probed 28 times since 9/5/2026. It answered in 28 of them (100.0%), a near-uninterrupted record. Median response time is 262 ms, placing it among the faster endpoints. Its tool list could not be read; the server is closed to direct calls.

Look up Indian HSN and GST codes by description or product name (4,676 entries).

Agent readability score

Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.

Agent readability score

HSN Classifier tools are clear but lack parameter specificity and tool differentiation.based on measured tool list

Strengths

Clear tool naming for code lookup
Error handling for unmatched codes

Weaknesses

Classify_product's parameter logic is ambiguous
Search_hsn and classify_product overlap in product name use

lookup_hsn — Parameter schema lacks input validation details
classify_product — 'matched_tokens' output is undefined

Verdict

Tools are functional but need clearer parameter definitions. Overlap between search_hsn and classify_product could confuse agents. Improve documentation on scoring logic and error boundaries.

Era history

Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
