Security check

How secure is the Browser Compat MCP Server MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Browser Compat MCP Server holds up.

✓ Verified directory serverBrowser Compat MCP Server · caseyjhand.com

Official endpoint

Operated by Browser Compat MCP Server (caseyjhand.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 Browser Compat MCP Server adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
