Love the MCP Inspector but tired of npx and localhost? Paste a server URL and gate connects, lists every tool, and grades it A–F for security — right in your browser, no install, no login.
The official inspector runs locally via npx. This runs in your browser — paste a URL and go.
Beyond listing tools, every tool gets an A–F grade: prompt injection, hidden instructions, over-broad permissions, provenance.
Publish a report to a permanent URL with an embeddable A–F badge for your README.
When you're ready, connect the server to gate for continuous re-scans, drift alerts, and per-tool rules.
The official MCP Inspector is great for local debugging. This complements it when you want a quick hosted check, a security grade, or a report to share.
