## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1573 tokens (~314/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 66, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (5)

### `get_safe_zone` (~172 tokens)

Get vertical video safe zone

Returns the approximate areas of a vertical (9:16) video frame that the app interface covers on Instagram Reels, TikTok, YouTube Shorts or Instagram Stories: unsafe margins in pixels and percent, the safe rectangle for text, the position of the right-hand button column and short placement guidance. Values are measured on 1080x1920 and scaled to the given frame size.

Input parameters:

- `height` (integer): Frame height in pixels. Default 1920.
- `platform` (string, required): Vertical video platform: 'reels' (Instagram Reels), 'tiktok', 'shorts' (YouTube Shorts), 'story' (Instagram Stories) or 'all' (the strictest margins of all four combined).
- `width` (integer): Frame width in pixels. Default 1080.

### `check_text_position` (~296 tokens)

Check text position against platform UI

Checks whether a rectangular text box (caption, title or logo) on a vertical video frame stays inside the safe zone of Instagram Reels, TikTok, YouTube Shorts or Instagram Stories. Reports which interface element it overlaps (top bar, bottom caption area, right button column, edge margins, optionally the Reels comment-reply sticker) and suggests the nearest position that clears them. Coordinates are pixels from the top-left corner of the frame.

Input parameters:

- `canvas_height` (integer): Frame height in pixels. Default 1920.
- `canvas_width` (integer): Frame width in pixels. Default 1080.
- `height` (number, required): Text box height in pixels.
- `include_comment_sticker` (boolean): Reels only: also test against the comment-reply sticker band (approximately y 300-560 px on 1080x1920). Default false.
- `platform` (string, required): Vertical video platform: 'reels' (Instagram Reels), 'tiktok', 'shorts' (YouTube Shorts), 'story' (Instagram Stories) or 'all' (the strictest margins of all four combined).
- `width` (number, required): Text box width in pixels.
- `x` (number, required): Left edge of the text box in pixels, measured from the left of the frame.
- `y` (number, required): Top edge of the text box in pixels, measured from the top of the frame.

### `calculate_bitrate` (~428 tokens)

Calculate video bitrate and file size

Calculates the file size of a video export from its duration and bitrate, or (when target_size_mb is given) the highest video bitrate that fits that size with a 2% safety margin. Without an explicit bitrate it uses the reference value for the platform, resolution and frame rate (YouTube and Vimeo recommendations, Apple ProRes target data rates, or Rast's delivery target for Instagram and TikTok, which publish none). Also returns size-limit warnings (Meta 4 GB, TikTok ads 500 MB / 516 kbps) and a two-pass ffmpeg command.

Input parameters:

- `audio_kbps` (number): Audio bitrate in kbps; 0 = no audio. Default 320.
- `duration_seconds` (number, required): Video length in seconds (e.g. 90 for 1:30).
- `fps` (number): Frame rate, e.g. 24, 25, 29.97, 30, 50, 60. Default 30. 48 fps and above use the high-frame-rate tables.
- `platform` (string): Delivery target used for the reference bitrate: 'youtube', 'youtube_hdr', 'vimeo', 'instagram', 'tiktok', or a ProRes flavour ('prores_proxy', 'prores_lt', 'prores_422', 'prores_hq', 'prores_4444', '…
- `resolution` (string): '720p', '1080p' (also 1080x1920 vertical), '1440p', '2160p' (4K UHD) or 'dci4k' (4096x2160). Default '1080p'.
- `target_size_mb` (number): If set, calculate the maximum video bitrate that fits this file size in megabytes (1 MB = 1,000,000 bytes) instead of the file size.
- `video_bitrate_mbps` (number): Video bitrate in Mbps to calculate the file size with. Omit to use the platform reference value.

### `validate_srt` (~285 tokens)

Validate SRT or WebVTT subtitles

Checks pasted SRT or WebVTT subtitle text and lists problems per subtitle: overlapping or out-of-order timings, gaps shorter than the minimum frame gap, reading speed (characters per second), line length, line count, too short or too long durations, and broken characters from a wrong encoding (mojibake such as 'é' or '’', with the probable correct text). Optionally returns a corrected SRT. The text is only processed for this response.

Input parameters:

- `fps` (number): Video frame rate used for the minimum gap. Default 25.
- `include_fixed_srt` (boolean): Also return a corrected SRT (encoding fixed, overlaps trimmed, long single lines split, short subtitles extended). Default false.
- `min_gap_frames` (integer): Minimum gap between subtitles in frames. Default 2.
- `preset` (string): Rule set: 'netflix' (42 chars/line, 2 lines, 17-20 CPS, 0.83-7 s; default), 'vertical' (short-form vertical video: 32 chars/line, 2 lines, 17-20 CPS, 1-5 s) or 'children' (42 chars/line, 13-17 CPS).
- `srt_text` (string, required): Full text of the .srt or .vtt file.

### `export_settings` (~160 tokens)

Recommended video export settings

Returns recommended export settings for uploading a finished video to YouTube (SDR or HDR), Vimeo, Instagram Reels or TikTok, or for a ProRes archive master: container, codec, resolution, frame rate, bitrate, colour and audio, plus links to each platform's official spec page and a short step list that works in any editor.

Input parameters:

- `orientation` (string): 'vertical' 9:16 (default) or 'horizontal' 16:9; changes the frame size given.
- `platform` (string, required): 'youtube', 'youtube_hdr', 'vimeo', 'instagram_reels', 'tiktok' or 'prores_master'.
- `resolution` (string): '1080p' (default) or '4k'.
