What your AI can do with unmarking
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “inspect_file”: Reads the C2PA content credential embedded in a file and reports its signer, including whether the file was made with Claude. Nothing is mod.”
“Use “strip_file”: Removes the C2PA content credential from a file and returns a download link for the cleaned copy. Pixels, frames and samples stay untouched.”
How secure is the unmarking MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how unmarking holds up.
Official endpoint
Operated by unmarking (unmark.ing) 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 unmarking adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

The actual tools unmarking exposes
Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
inspect_file — Reads the C2PA content credential embedded in a file and reports its signer, including whether the file was made with Claude. Nothing is mod
strip_file — Removes the C2PA content credential from a file and returns a download link for the cleaned copy. Pixels, frames and samples stay untouched.

https://api.unmark.ing/mcpQuestions, answered
Is there an official unmarking MCP server?
Yes — unmarking operates its own remote MCP server at api.unmark.ing. 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 unmarking to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick unmarking in the directory. No account or sign-in is needed. From then on, unmarking's tools are available in every client you've connected to gate.
Do I need to host anything?
No. unmarking runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the unmarking 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 unmarking in minutes. No credit card required.
