## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "calculate_gst",
    "arguments": {}
  }
}
```

## Why calculate_gst is rated Low

GST calculation is a read-only operation that retrieves and applies tax computation rules. Context shows this is part of a master data/calculation service ('tax calculations' include 'GST' per server description) analogous to EMI and FD maturity calculators on the same server. These are deterministic computations without side effects.

From the tool's own definition: "Tool name is 'calculate_gst' with empty description. GST calculation tools perform computational lookups of tax rates and formulas based on input data (goods/services classification, amounts)."

## Use case

AI agents call calculate_gst 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp India Stack:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "calculate_gst": {}
  }
}
```
