Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Proper Job Building Cost Calculator holds up.
gate scanned 3 tools on Sep 28, 2026 for prompt injection and risky tool definitions — nothing to flag.
Operated by Proper Job Building Cost Calculator (proper-job.uk) 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 Proper Job Building Cost Calculator adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
