What your AI can do with postcache
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “upload_media”: Upload an image or video for a social platform. Returns a public URL that passes the platform media rules, or the problems with fixes. With.”
“Use “check_media”: Check a file against a platform without storing it. With convert, also says whether conversion can fix it.”
“Use “get_media”: Status (converting, ready, failed), URL, expiry and fetch count of an uploaded file.”
“Use “delete_media”: Delete an uploaded file now (call after the post is published).”
How secure is the postcache MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how postcache holds up.
Official endpoint
Operated by postcache (postcache.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If postcache adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Who runs the postcache MCP server?
The postcache MCP server at a glance
https://postcache.dev/mcpQuestions, answered
Is there an official postcache MCP server?
Yes — postcache operates its own remote MCP server at postcache.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect postcache to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick postcache in the directory. No account or sign-in is needed. From then on, postcache's tools are available in every client you've connected to gate.
Do I need to host anything?
No. postcache runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the postcache MCP server safe to connect?
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.
Is it free?
Yes — you can get started with gate for free and connect postcache in minutes. No credit card required.
