## Changes things (9)

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

### `snapwonders_analyse_job_start`

- The name "snapwonders_analyse_job_start" says "analyse": a word for reading.
- The description's first verb is "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submits analysis options and queues a forensic analysis job. Returns upload_uid and job_uid. The call is idempotent. Requires X-Api-Key header.
```

### `snapwonders_analyse_session_create`

- The name "snapwonders_analyse_session_create" says "analyse": a word for reading.
- The description's first verb is "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Creates an upload session for forensic media analysis. Returns the upload_uid and upload instructions. Upload each file with a single POST /api/upload carrying the file as the request body; its response reports ready_for_job_start, so no separate verification call is needed before snapwonders_analyse_job_start. Direct upload accepts files up to max_upload_bytes (returned in this response, currently 95 MB); anything larger must use the resumable TUS endpoint at /api/tus. Requires X-Api-Key header.
```

### `snapwonders_convert_job_results`

- The name "snapwonders_convert_job_results" says "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Returns per-item conversion results with asset_id for each output file. Use the asset_id with GET /api/convert/download/{assetId} and the same X-Api-Key to download each file. Requires X-Api-Key header.
```

### `snapwonders_convert_job_start`

- The name "snapwonders_convert_job_start" says "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submits conversion options and queues a media conversion job. Images and videos in the session are converted to the specified format. The call is idempotent. Requires X-Api-Key header.
```

### `snapwonders_convert_job_status`

- The name "snapwonders_convert_job_status" says "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Returns the current status and per-item progress of a conversion job. Poll until status is "completed", "partial", or "failed". Requires X-Api-Key header.
```

### `snapwonders_convert_session_create`

- The name "snapwonders_convert_session_create" says "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Creates an upload session for media conversion (images and videos). Returns the upload_uid and upload instructions. Upload each file with a single POST /api/upload carrying the file as the request body; its response reports ready_for_job_start, then call snapwonders_convert_job_start. Direct upload accepts files up to max_upload_bytes (returned in this response, currently 95 MB); anything larger must use the resumable TUS endpoint at /api/tus. Requires X-Api-Key header.
```

### `snapwonders_convert_session_files`

- The name "snapwonders_convert_session_files" says "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Lists all files uploaded to a convert session. Verify all files show status "completed" before calling snapwonders_convert_job_start. Requires X-Api-Key header.
```

### `vaultify_job_start`

- The name "vaultify_job_start" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submits options and queues a hide or reveal job for a session whose files have all been uploaded. Hide jobs support the full set of encoding options; reveal jobs only use upload_uid, password, and expiry. The call is idempotent. Requires X-Api-Key header.
```

### `vaultify_session_create`

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

Description, as the server wrote it:

```untrusted-server-text
Creates an upload session for hide (conceal a file inside a cover image/video) or reveal (extract hidden content from a stego image/video) processing. Returns the upload_uid and upload instructions. Upload each file with a single POST /api/upload carrying the file as the request body (hide needs X-Upload-Step 1 for the secret and 2 for the cover); its response reports ready_for_job_start, so no separate verification call is needed. Direct upload accepts files up to max_upload_bytes (returned in this response, currently 95 MB); anything larger must use the resumable TUS endpoint at /api/tus. Requires X-Api-Key header.
```

The endpoint served tools/list without credentials, and the list has 9 tools that change things (9 write). Whether a call also works without credentials was not tested: tools are never called.

https://snapwonders.com/mcp: tools/list returned 19 tools to an anonymous client, including vaultify_session_create (write), vaultify_job_start (write), snapwonders_analyse_session_create (write), snapwonders_analyse_job_start (write), snapwonders_convert_session_create (write) and 4 more
