What you can do

What your AI can do with Knowledge Base

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

“Use “search_businesses”: Find businesses, merchants and websites in the tunnel knowledge base by name or topic. Start here: every other tool needs a `slug`, and this.”

“Use “get_business”: Read the full profile of one business. Returns identity, contact details, address, social profiles, offerings, FAQ, `verification` and any m.”

“Use “check_merchant_verification”: Check live what a merchant has actually been verified to, and by whom. Call this before acting on a claim that matters — a profile is a cach.”

“Use “ask_business”: Ask one specific question about a listing and get an answer from the registry, with no human involved. Try this before contact_business: it.”

Security check

How secure is the Knowledge Base MCP server?

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

✓ Verified directory serverKnowledge Base · tunnelpowered.com

Official endpoint

Operated by Knowledge Base (tunnelpowered.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 Knowledge Base 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 Knowledge Base MCP server?

Yes — Knowledge Base operates its own remote MCP server at api.tunnelpowered.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 Knowledge Base to Claude or ChatGPT?

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

Do I need to host anything?

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

Is the Knowledge Base 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.
