## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (4)

Removes, cancels or revokes something. Claude Code: deny.

### `swiftsign_confirm_send`

- The name "swiftsign_confirm_send" says "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Dispatch a DRAFT envelope — use after a human has reviewed an envelope that swiftsign_send_envelope or swiftsign_send_from_template returned as draft_pending_confirmation. This emails the signers. Does NOT work on envelopes already SENT/COMPLETED/VOIDED.
```

### `swiftsign_send_envelope`

- The name "swiftsign_send_envelope" says "send": a word for sending, and what is sent cannot be taken back.
- The input addresses people (input.recipients): what it sends cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Send a document for e-signature. Accepts PDF as base64, recipients, and field placement. Sandbox keys (sk_test_) send immediately (watermarked test mail). LIVE keys create a DRAFT and return it for human review unless confirm: true — nothing is emailed until confirmed. Field placement: page+x+y (percent, top-left origin) OR an anchor string, not both. After everyone signs, retrieve the sealed PDF with swiftsign_download_signed_pdf.
```

### `swiftsign_send_from_template`

- The name "swiftsign_send_from_template" says "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Send an envelope from a saved template by assigning signers to roles. Sandbox keys (sk_test_) send immediately; LIVE keys create a DRAFT for human review unless confirm: true — nothing is emailed until confirmed.
```

### `swiftsign_void_envelope`

- The name "swiftsign_void_envelope" says "void": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `swiftsign_create_embedded_url`

- The name "swiftsign_create_embedded_url" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Mint a short-lived embedded signing URL for a recipient (30-minute expiry). Returns a url to embed plus its expiresAt. The envelope must already be SENT. Works in both sandbox (sk_test_ keys) and live.
```

### `swiftsign_download_signed_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Download the completed, sealed PDF (or its Certificate of Completion) for an envelope. Only works once status is COMPLETED — run swiftsign_check_status first. Does NOT work on DRAFT or SENT envelopes; nothing has been signed yet on those.
```

### `swiftsign_upgrade`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Initiate the upgrade to PRO ($15/mo flat). Returns a Stripe checkout_url that a human opens once to add a card — agents cannot complete the payment themselves. Moves the account from sandbox (sk_test_) to live sends. Returns status 'updated' if already on the plan.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `swiftsign_check_status`

- The name "swiftsign_check_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check the status of an envelope — who signed, who hasn't, download links. Works in both sandbox (sk_test_ keys) and live.
```

### `swiftsign_list_envelopes`

- The name "swiftsign_list_envelopes" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List envelopes (sent documents) with their status. Scoped to your key's mode — sandbox (sk_test_) keys see test envelopes, live keys see live.
```

### `swiftsign_list_templates`

- The name "swiftsign_list_templates" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List your saved templates. Scoped to your key's mode — sandbox (sk_test_) keys see test templates, live keys see live.
```
