What it does

PrismPoster Creator Tools is an MCP server, a connector that lets an AI assistant use it as a tool. It can be used hosted (nothing to install) or installed locally.

From the publisher's description, Electra Index matched it to one capability: social media management. That makes it a candidate for tasks such as manage social media accounts or monitor brand mentions.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

7 tools offered to AI assistants

  • get_social_media_placement · Get exact frame dimensions, aspect ratio, first-party safe-area insets (px), usable box, and official documentation URL for a social media placement (e.g. instagram-reels, tiktok-video, youtube-shorts, youtube-channel-banner). Optionally pa
  • list_social_media_placements · List all social media video and image placements with dimensions, aspect ratios, safe-area pixel insets, and first-party documentation URLs. Optionally filter by platform.
  • calculate_aspect_ratio · Simplify pixel dimensions to their aspect ratio, compute even-pixel encoder dimensions, solve a missing width or height, and optionally compute centre-crop and letterbox/pad plans for a target ratio.
  • estimate_video_bitrate · Estimate encoded video file size (MB, GB, MiB, GiB) from duration and bitrate, or compute the maximum video bitrate that fits under a file-size cap (such as Discord 10 MB / 20 MB limits).
  • convert_subtitles · Parse, validate, time-shift, and convert subtitle files between SubRip (srt) and WebVTT (vtt). Reports overlapping, zero-duration, or out-of-order cues.
  • estimate_tempo · Estimate BPM and stability from tap timestamps in milliseconds, or compute delay times (straight, dotted, triplet) and bar durations for a given BPM and time signature.
  • get_prismposter_capabilities · Retrieve PrismPoster studio capabilities, AI video/image/music/Remake specifications, credit-pack pricing facts, and canonical URLs for citation.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
