gstinapi-mcp
An MCP server for gstinapi.in — GSTIN verification, GST return/compliance history, HSN/SAC code lookup, and India's MCA company registry, callable directly from Claude and other MCP clients.
This is a thin wrapper around the REST API at gstinapi.in/docs. It holds no logic of its own — every tool call is one authenticated HTTP request, and the response is returned as-is.
Setup
- Get a free API key — 100 lookups on signup, no card required: https://www.gstinapi.in/register
- Add this server to your MCP client config, e.g. for Claude Desktop / Claude Code (
claude_desktop_config.jsonor.mcp.json):
{
"mcpServers": {
"gstinapi": {
"command": "npx",
"args": ["-y", "gstinapi-mcp"],
"env": {
"GSTINAPI_API_KEY": "your-api-key-here"
}
}
}
}
No install step — npx fetches it on first use.

search_hsn_codes | Find HSN/SAC codes from a description |

Accuracy notes
- Every GSTIN lookup queries the GST network live — nothing is cached.
resolve_gstin_to_companyis a probabilistic match, not an official mapping — no government dataset links a GSTIN to a CIN. Treat it as a scored guess (high/medium/lowconfidence), never as a confirmed fact.- No GST rate is returned from the HSN endpoints — a rate depends on more than the code alone, and the government's own master publishes no rate column.
