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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_receipt",
    "arguments": {
      "envelope_id": "<envelope_id>"
    }
  }
}
```

## Why get_receipt is rated Low

This is a read-only query operation that retrieves cryptographic evidence and audit metadata (hashes, signatures, timestamps) associated with a signing envelope. While the data retrieved is sensitive (signature hashes, audit chain information), the tool itself performs no modification, deletion, or execution—it only queries and returns existing records.

From the tool's own definition: "Tool returns envelope records, signing receipts, and metadata ('Return the envelope record...per-signer signing receipts, and OpenTimestamps anchor metadata'). Explicitly states 'Evidence only, never PDF bytes' — retrieval operation with no side effects."

## Use case

AI agents call get_receipt to retrieve information from FreeSign — Free e-signature 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 FreeSign — Free e-signature:

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