What your AI can do with Circuit
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “find_skills”: Search Circuit's paid AI agent skills by capability, e.g. 'phishing link', 'token price' or 'summarize a web page'. Returns each skill's id,.”
“Use “get_skill”: Full details for one skill: input and output schema, a real example, price, 30-day usage, uptime, rating and how to pay for it. Free.”
“Use “try_skill”: Run a skill once for free on a small input (text up to 500 characters). 3 free calls per day. Paid calls have no such limits.”
“Use “list_recipes”: Workflows that chain several skills (vet a token, install a dependency safely, screen untrusted input and more), with the cost of one run. F.”
How secure is the Circuit MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Circuit holds up.
Official endpoint
Operated by Circuit (circuit.family) 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 Circuit 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.
Pick Circuit
Choose Circuit in the gate directory. No sign-in needed.
Use it anywhere
Circuit's tools are live in every AI client you've connected — with rules and logging built in.

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