Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how ExactMelt holds up.
gate scanned 6 tools on Nov 4, 2026 for prompt injection and risky tool definitions — nothing to flag.
Operated by ExactMelt (exactmelt.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If ExactMelt adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose ExactMelt in the gate directory. No sign-in needed.
ExactMelt's tools are live in every AI client you've connected — with rules and logging built in.

https://exactmelt.com/api/mcpYes — ExactMelt operates its own remote MCP server at exactmelt.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
Add gate's gateway URL to your AI client once, then pick ExactMelt in the directory. No account or sign-in is needed. From then on, ExactMelt's tools are available in every client you've connected to gate.
No. ExactMelt runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
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.
Yes — you can get started with gate for free and connect ExactMelt in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
