Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “payability_verdict”: Latest payability observation for one exact resource URL (path and query included), with the meaning of the verdict, remediation if it c.”
“Use “find_endpoints”: Search the catalogue by host or URL substring. Returns up to `limit` endpoints with their latest verdict, plus the total match count. Us.”
“Use “catalogue_stats”: Size and health of the x402 catalogue as of the latest full scan: resources, hosts, verdict counts, and payable endpoints per network.”
“Use “host_summary”: Summary for a host (no time series): first/last seen, current verdict mix, n_resources, total verdict changes, gone_since if absent from.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Nsgoods Workbench MCP holds up.
gate scanned 8 tools on Sep 20, 2026 for prompt injection and risky tool definitions — nothing to flag.
Operated by Nsgoods Workbench MCP (nsgoods.org) 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 Nsgoods Workbench MCP 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 Nsgoods Workbench MCP in the gate directory. No sign-in needed.
Nsgoods Workbench MCP's tools are live in every AI client you've connected — with rules and logging built in.

No. Nsgoods Workbench MCP 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.
