What your AI can do with Ratchet
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “ratchet_get_circuit”: Call this when a begin returned "approval_required" or "denied" and the reason mentions a circuit breaker. A breaker opens when an effect ty.”
“Use “ratchet_begin_effect”: Call this IMMEDIATELY BEFORE performing any side effect that touches the outside world (sending a message, charging a card, creating a resou.”
“Use “ratchet_report_effect”: Call this IMMEDIATELY AFTER performing an action that ratchet_begin_effect authorised. Pass the lease_token you were given. Report "succeede.”
“Use “ratchet_extend_lease”: Call this periodically during a long action you were authorised to perform, before the lease expires. It tells Ratchet you are alive and ext.”
How secure is the Ratchet MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Ratchet holds up.
Official endpoint
Operated by Ratchet (ratchetgate.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 Ratchet adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

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