What you can do

What your AI can do with Citation Check

Real prompts you can type the moment it's connected — no setup, no docs to read.

“Use “check_citation”: Fetch a URL and report whether it exists, and whether the source names the same entity as the claim you attach to it. These are two differen.”

“Use “verdict_meanings”: The exact semantics of every status and relevance value, including what this checker cannot determine. Read once before trusting a verdict.”

Security check

How secure is the Citation Check MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Citation Check holds up.

✓ Verified directory serverCitation Check · fly.dev

Official endpoint

Operated by Citation Check (fly.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 Citation Check adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

FAQ

Questions, answered

Is there an official Citation Check MCP server?

Yes — Citation Check operates its own remote MCP server at exmachina-ai.fly.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 Citation Check to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick Citation Check in the directory. No account or sign-in is needed. From then on, Citation Check's tools are available in every client you've connected to gate.

Do I need to host anything?

No. Citation Check runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the Citation Check 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.
