WHAT IT DOES

What lookup_hsn_code does on Mcp India Stack

AI agents call lookup_hsn_code to retrieve information from Mcp India Stack without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why lookup_hsn_code is rated Low

HSN code lookups are informational queries against a static reference database. They retrieve data without side effects, authentication requirements, or ability to modify records. The empty description lowers confidence slightly, but the context of master data lookups and the server's offline-first nature confirm this is a simple Read operation with minimal risk if misused by an AI agent.

From the tool's definition Tool name 'lookup_hsn_code' indicates a lookup operation for HSN (Harmonized System of Nomenclature) codes, which are master data. Server description explicitly lists 'master data lookups (IFSC, Pincode, HSN/SAC)' as read-only reference data operations.

RECOMMENDED RULE

The rule that runs lookup_hsn_code safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp India Stack, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For lookup_hsn_code, this is the rule to start with:

lookup_hsn_code Allowed

lookup_hsn_code is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "lookup_hsn_code": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp India Stack, apply this rule, and every lookup_hsn_code call is checked against it from then on.
