What your AI can do with CAZ Cost
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “list_zones”: List every UK Clean Air Zone with the daily charge each council publishes, per vehicle class, plus the London Congestion Charge and ULEZ whi.”
“Use “zone_charges”: Get one zone by id: its daily charge for each vehicle class, its notes, its penalty figures and the source URLs the numbers came from.”
“Use “trip_cost”: Cost one trip through a zone: daily rate x days, plus the penalty if it went unpaid. Returns chargeable=false when that vehicle class is not.”
How secure is the CAZ Cost MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how CAZ Cost holds up.
Security grade A
gate scanned 3 tools on Oct 7, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by CAZ Cost (rowb.app) 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 CAZ Cost adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

https://caz-cost.rowb.app/mcpQuestions, answered
Is there an official CAZ Cost MCP server?
Yes — CAZ Cost operates its own remote MCP server at caz-cost.rowb.app. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect CAZ Cost to Claude or ChatGPT?

Do I need to host anything?
No. CAZ Cost runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the CAZ Cost MCP server safe to connect?
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.
