## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__fileconvert__get_download_url` `mcp__fileconvert__get_upload_url` `mcp__fileconvert__list_formats` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__fileconvert__get_download_url` `mcp__fileconvert__get_upload_url` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `convert_file`

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

Description, as the server wrote it:

```untrusted-server-text
End-to-end conversion of a remote file: fetches 'source_url' (with SSRF protection), uploads it to FileConvert, and starts a conversion from 'source_format' to 'target_format' (named by extension, e.g. png → webp, docx → pdf). Returns the conversion 'job_id' and the uploaded 'file_id'. Poll progress with get_job_status(job_id); when the status is Completed, call get_download_url(job_id) for the result. Conversions consume account credits. For a file you hold locally, use upload_file + start_conversion instead.
```

### `start_conversion`

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

Description, as the server wrote it:

```untrusted-server-text
Starts a conversion of a file that is already in FileConvert (a 'file_id' from upload_file or from an earlier job) from 'source_format' to 'target_format' (named by extension). Returns the 'job_id' to poll with get_job_status. Conversions consume account credits.
```

### `upload_file`

- The name "upload_file" says "upload": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Uploads file bytes (base64) into FileConvert and returns a 'file_id'. Use this when the file is not reachable by URL, then call start_conversion(file_id, source_format, target_format). For files reachable over http(s), convert_file is a single call instead.
```

## Only reads (5)

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

### `get_balance`

- The name "get_balance" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the credit balance of the signed-in account, plus where to get more. Every conversion costs credits; call this when a conversion fails with 'no credits' or when the user asks how many conversions they have left.
```

### `get_download_url`

- The name "get_download_url" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "file": it reads files. The input names a file (input.file_id), and the tool reads: it reads files.
- Tag untrusted-input: The name "get_download_url" says "get" and "url": it reads web pages, which anyone can write. The description's first sentence says "return" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Returns the download URL of a converted file. Pass 'job_id' (conversion uid) to resolve the converted file of a finished conversion, or 'file_id' to download a known file uid directly. The URL needs no authentication (the unguessable file id is the capability), so it can be handed to the user or another system as-is. It stops working when the file's retention ends — about one hour after conversion by default — so download or share it promptly.
```

### `get_job_status`

- The name "get_job_status" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the current status of a conversion job. Statuses: Pending → Processing → Completed or Failed (Failed includes the reason). Poll every 2–3 seconds after convert_file / start_conversion; when Completed, call get_download_url. Also returns the full conversion object, which includes the converted file uid once the job has finished.
```

### `get_upload_url`

- The name "get_upload_url" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "file": it reads files.
- Tag untrusted-input: The name "get_upload_url" says "get" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Returns instructions for uploading an agent-local file into FileConvert. FileConvert does NOT use presigned upload URLs; instead you upload the file bytes directly to the gateway as a multipart/form-data POST. The response gives the exact URL, HTTP method, form field name and required Authorization header. After uploading you receive a file object whose 'uid' can be passed to a conversion. If your file is reachable over http(s), prefer convert_file(source_url, target_format) which fetches and uploads it for you. Works without a token (the upload itself needs one).
```

### `list_formats`

- The name "list_formats" says "list": a word for reading.
- Tag private-data: The description's first sentence says "return" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Returns the file formats FileConvert can read and write, along with the format-type categories (image, video, document, audio, …). Use this first to discover valid 'format_type', 'source_format' and 'target_format' identifiers before calling convert_file. Each format includes its numeric id, name, file extension and description. Optionally pass 'format_type' to filter to a single category. Works without a token.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `fileconvert`:

```json
{
  "permissions": {
    "allow": [
      "mcp__fileconvert__get_balance",
      "mcp__fileconvert__get_download_url",
      "mcp__fileconvert__get_job_status",
      "mcp__fileconvert__get_upload_url",
      "mcp__fileconvert__list_formats"
    ],
    "ask": [
      "mcp__fileconvert__convert_file",
      "mcp__fileconvert__start_conversion",
      "mcp__fileconvert__upload_file"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__fileconvert__get_download_url`: private-data, untrusted-input
- `mcp__fileconvert__get_upload_url`: private-data, untrusted-input
- `mcp__fileconvert__list_formats`: private-data

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://file-convert.online/api/mcp/v1/mcp: tools/list returned 8 tools to an anonymous client, including convert_file (write), start_conversion (write), upload_file (write)
