  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why validate_pan is rated Low

This tool performs a read-only validation and parsing operation on a PAN identifier. It retrieves structural information without creating, modifying, or deleting any data. The operations are: (1) format validation, and (2) entity type extraction. Both are informational queries with no persistent side effects.

From the tool's own definition: "Tool 'validates the format and structure' and 'extracts' information from a PAN number. No modifications, deletions, or side effects are performed—only validation and data extraction occur."

## Use case

AI agents call validate_pan to retrieve information from India Business 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 India Business:

```json

  "version": "1",

  }
}
```
