What your AI can do with Cyber Library
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_library”: Full-text search over the published pages of cyberlibrary.com (titles, descriptions, paths). Returns the best matches with their path and UR.”
“Use “get_page”: Returns a page of the Cyber Library as markdown with its metadata (title, URL, breadcrumbs, last update, contributors) and, for folders, the.”
“Use “list_topics”: Lists the direct children of a folder of the library (or the six top-level sections when no path is given): title, path, number of sub-pages.”
“Use “get_outline”: Indented outline of the library tree below a path (default: whole library) down to a given depth. Useful to understand how a domain is organ.”
How secure is the Cyber Library MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Cyber Library holds up.
Official endpoint
Operated by Cyber Library (cyberlibrary.com) 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 Cyber Library adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

Cyber Library's tools are live in every AI client you've connected — with rules and logging built in.

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