### Tool changes

- 2026-11-05 `remove_watermark` removed
  - AI watermark removal / inpainting for ONE image (JPG/PNG/WebP, <= 10 MB) supplied as a public URL. Optional `mask_image_url` (white = remove) or normalized `mask_rect` {x,y,width,height} in 0-1; with neither, the upstream auto-detect mode is used (support depends on the upstream). COPYRIGHT / ABUSE GATE: Use only on images you own or are explicitly licensed/authorized to edit. Do not remove copyright, ownership, attribution or license watermarks from third-party material, and do not bulk-strip watermarks from other people's content. Calls are rate-limited/metered by mcp-credit-gateway, require a valid sk_live_ key, and every attempt (including failures) is logged with an audit id for review. （仅处理自有或已获授权素材；禁止批量剥离他人版权水印；调用限频；失败可审计。） This tool is metered per call, accepts a single image per request, and returns an audit_id; bulk/automated third-party stripping is prohibited and may be blocked or reported. Cost: 3 credits per call; mcp-credit-gateway charges before forwarding the request.
- 2026-11-05 `add_watermark` removed
  - Add a visible text or image watermark to an image or PDF supplied as a public URL. Formats: JPG/PNG/WebP images up to 10 MB; PDF up to 30 MB. watermark_type=text requires `text` (<= 500 chars); watermark_type=image requires `watermark_image_url` (PNG/JPG/WebP, <= 5 MB, transparency supported). Position: top-left/top-center/top-right/center/bottom-left/bottom-center/bottom-right/tile. opacity 0.05-1, optional scale/font_size/color/rotation. For PDF, pass `pages` (e.g. "1-3,5") to limit pages. Synchronous. Cost: 2 credits per call; mcp-credit-gateway charges before forwarding the request. Requires Authorization: Bearer sk_live_... on the MCP endpoint.
- 2026-11-05 `upscale_image` added
  - Upscale an image from a public URL. POST {img, upscale} to ai.imgkits.com/api/restoration. `scale` is 2 (default) or 4 and is sent as `upscale`. Optional `face_enhance` is sent on the same body. There is no separate enhance_photo or enhance_face tool. Synchronous. Cost: 2 credits per call; mcp-credit-gateway charges before forwarding.
- 2026-11-05 `colorize_photo` added
  - Colorize a photo from a public URL. POST {img} to ai.imgkits.com/api/deoldify (AiController Shangse). Black-and-white photos work best; a response with a null URL is treated as failure. Synchronous. Cost: 2 credits per call; mcp-credit-gateway charges before forwarding. Requires Authorization: Bearer sk_live_... on tools/call.
- 2026-11-05 `count_text` added
  - Count characters, words, lines, and UTF-8 bytes for `text` (≤8000 chars). Latin words + CJK ideographs counted separately; pure algorithm, no upstream.

Privacy: Text is processed in-memory for this request only and is not stored. Do not send secrets, passwords, or personal data you would not paste into a public tool. Calls are rate-limited/metered by mcp-credit-gateway and require a valid sk_live_ key. （文本仅在本请求内存中处理、不落盘；请勿提交密钥/密码等敏感信息；调用限频。）
- 2026-11-05 `convert_text_style` added
  - Transform text with a pure in-Worker algorithm (no upstream HTTP). Pass required `text` (≤8000 chars) and `mode` one of: morse, binary, old_english, fancy, upper, lower, title, reverse.

- `decode_blind_watermark`: Read a blind watermark from an image (public http(s) URL). Uses the AiController CreateDecodeBlindWatermarkTask + GetDecodeBlindWatermarkResult async path. Start with `source_url`; the call waits up to `wait_seconds` (default 15, max 60) and returns a `job_id` if still running. Poll by calling again with only `job_id`; polling never creates a new upstream decode task. Returns `content` when readable. Cost: 2 credits per call, charged by mcp-credit-gateway before forwarding.
- `detect_language`: Detect the language of up to 20,000 characters. Uses a local Unicode-script + stopword/diacritic heuristic; no upstream call. Returns a language code, confidence, reliability flag and alternatives. Billing: free by default (COST_DETECT_LANGUAGE=0).
- `embed_blind_watermark`: Embed an invisible/blind watermark into an image supplied as a public URL (JPG/PNG/WebP/BMP, <= 10 MB; at least 64x64 px recommended). Uses the AiController EncodeBlindWatermark / Alibaba Cloud IMM path. Pass `watermark_text` (<= 512 chars, e.g. an order id), or omit it to use the server-held BLIND_WATERMARK_KEY secret; the embedded content is never echoed back. `model` is DWT (default, more robust) or DCT; optional `strength` 1-10. Synchronous. Cost: 2 credits per call, charged by mcp-credit-gateway before forwarding.
- `extract_tables`: Extract tables from PDFs and images as HTML plus a row/column matrix. Merged cells are expanded; only the top-left cell carries content and other covered cells are empty strings. Returns row_count, column_count, page_idx, and bbox for each table.

Input: 1-5 public https file URLs, each ≤20 MiB. Supported: pdf, png, jpeg, webp, bmp, tiff. DOCX is not supported in this release. Private, local, and metadata hosts are rejected.

Table structure is model-recognized, so complex, borderless, or handwritten tables may contain errors. Processing is asynchronous and this call polls until done or times out after about 75 seconds.

This Worker does not store uploaded files or results. Upstream MinerU task data is temporary (≤24h).

Billing: charged before the MinerU job is created (default 1 credit per tool call). No automatic refunds.

Input: 1-5 public https file URLs, each ≤20 MiB. Supported: pdf, png, jpeg, webp, bmp, tiff. DOCX is not supported in this release. Private, local, and metadata hosts are rejected.

Tables inside an image are returned as positioned table_cell blocks. Processing is asynchronous and this call polls until done or times out after about 75 seconds.

This Worker does not store uploaded files or results. Upstream MinerU task data is temporary (≤24h).
