Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 105 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name rast-creator-tools.

  • Pass
    Lists tools

    tools/list returned 5 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 105 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 105 ms over 2 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    2 of 2 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Pass
    Stable tool list

    No tool was removed and no required parameter was added in the last 30 days.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    26 of 26 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass

Capabilities

Tools 5

calculate_bitrate

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.

Discovered
check_text_position

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.

Discovered
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.

Discovered
get_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.

Discovered
validate_srt

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.
