## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `convert`

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

Description, as the server wrote it:

```untrusted-server-text
Convert an uploaded document payload with TweekIT.

The file must already be base64 encoded (see `blob`). The conversion can be
resized and cropped by providing optional geometry parameters. For raster
outputs, set `alpha`/`bgColor` to control transparency handling.

Args:
    inext: Source file extension such as `pdf`, `docx`, or `png`.
    outfmt: Desired output format (`Fmt` in the API body).
    blob: Base64 encoded document payload (`DocData`).
    apiKey: TweekIT API key (`ApiKey` header). Falls back to `TWEEKIT_API_KEY` env var.
    apiSecret: TweekIT API secret (`ApiSecret` header). Falls back to `TWEEKIT_API_SECRET` env var.
    noRasterize: Forwarded to TweekIT to skip rasterization when possible.
    width: Optional pixel width to request in the output.
    height: Optional pixel height to request in the output.
    x1: Left crop coordinate in source pixels.
    y1: Top crop coordinate in source pixels.
    x2: Right crop coordinate in source pixels.
    y2: Bottom crop coordinate in source pixels.
    page: Page number to extract for multipage inputs.
    alpha: Whether the output should preserve alpha transparency.
    bgColor: Background color to composite behind transparent pixels.

Returns:
    A FastMCP `Image` or `File` payload, or an error description.
```

### `convert_url`

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

Description, as the server wrote it:

```untrusted-server-text
Download a remote file and convert it with TweekIT in one step.

This helper first fetches `url`, infers the input extension when possible,
and then forwards the bytes to `convert`. Supply `fetchHeaders` when the
remote resource needs authentication or custom headers.

Args:
    url: Direct download URL for the source document or image.
    outfmt: Desired output format (`Fmt`).
    apiKey: TweekIT API key (`ApiKey` header). Falls back to `TWEEKIT_API_KEY` env var.
    apiSecret: TweekIT API secret (`ApiSecret` header). Falls back to `TWEEKIT_API_SECRET` env var.
    inext: Optional override for the source extension if it cannot be
        detected from the URL or response headers.
    noRasterize: Forwarded to TweekIT to skip rasterization when possible.
    width: Optional pixel width to request in the output.
    height: Optional pixel height to request in the output.
    x1: Left crop coordinate in source pixels.
    y1: Top crop coordinate in source pixels.
    x2: Right crop coordinate in source pixels.
    y2: Bottom crop coordinate in source pixels.
    page: Page number to extract for multipage inputs.
    alpha: Whether the output should preserve alpha transparency.
    bgColor: Background color to composite behind transparent pixels.
    fetchHeaders: Optional mapping of HTTP headers to include when fetching.

Returns:
    A FastMCP `Image` or `File` payload, or an error description.
```

## Only reads (3)

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

### `doctype`

- The description's first verb is "retrieve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Retrieve a list of supported file formats or map a file extension to its document type.

Args:
    apiKey (str): The API key for authentication. Falls back to TWEEKIT_API_KEY when omitted.
    apiSecret (str): The API secret for authentication. Falls back to TWEEKIT_API_SECRET when omitted.
    extension (str): The file extension to query (e.g., 'jpg', 'pdf') or leave off or use '*' to return all supported input formats.

Returns:
    Dict[str, Any]: A dictionary containing the supported file formats or an error message.
```

### `fetch`

- The name "fetch" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch a URL and return content.

- Images return as FastMCP Image.
- PDFs return as File(format="pdf").
- Text/JSON return as a JSON payload with metadata and text.
```

### `search`

- The name "search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Simple web search using DuckDuckGo HTML endpoint.

Returns a list of {title, url, snippet} objects. Best‑effort parsing.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__tweekit__doctype",
      "mcp__tweekit__fetch",
      "mcp__tweekit__search"
    ],
    "ask": [
      "mcp__tweekit__convert",
      "mcp__tweekit__convert_url"
    ],
    "deny": []
