# swiftsign_void_envelope

Cancel/void an envelope that hasn't been completed yet. Signers can no longer sign a voided envelope. Works in both sandbox (sk_test_ keys) and live.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `envelopeId` | string | yes | The envelope ID to void |

Parameters from the server's own tool schema.

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

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

## Why swiftsign_void_envelope is rated Critical

Voiding an envelope is an irreversible action that permanently disables signing capability for a document in flight. Once voided, the envelope cannot be recovered or re-enabled for signing, making this a destructive operation. The high severity reflects the potential business impact of an agent erroneously voiding critical documents, especially since the tool works in both sandbox and live environments.

From the tool's own definition: "Tool description states 'Cancel/void an envelope' and 'Signers can no longer sign a voided envelope.' The word 'void' combined with the irreversible effect of preventing further signing indicates an action that cannot be undone."

## Use case

AI agents call swiftsign_void_envelope to permanently remove resources in Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "swiftsign_void_envelope"
  ]
}
```
