Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “get_social_media_placement”: Look up one social media placement by id and return its frame size, aspect ratio, first-party safe-area insets in px, usable box, and the of.”
“Use “list_social_media_placements”: List every supported social media placement (or one platform's) with frame size, aspect ratio, safe-area insets in px, usable box and first-.”
“Use “check_safe_area”: Check whether a rectangle (a caption, logo or button, in px on the placement's own frame, origin top-left) stays inside the placement's safe.”
“Use “calculate_aspect_ratio”: Reduce any pixel size to its simplest aspect ratio (1920x1080 is 16:9) and the nearest even size an H.264 encoder accepts, and, given a targ.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how PrismPoster Creator Tools holds up.
Operated by PrismPoster Creator Tools (prismposter.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If PrismPoster Creator Tools adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose PrismPoster Creator Tools in the gate directory. No sign-in needed.
PrismPoster Creator Tools's tools are live in every AI client you've connected — with rules and logging built in.

https://www.prismposter.com/api/mcpYes — PrismPoster Creator Tools operates its own remote MCP server at www.prismposter.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
Add gate's gateway URL to your AI client once, then pick PrismPoster Creator Tools in the directory. No account or sign-in is needed. From then on, PrismPoster Creator Tools's tools are available in every client you've connected to gate.
No. PrismPoster Creator Tools runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Yes — you can get started with gate for free and connect PrismPoster Creator Tools in minutes. No credit card required.
