What your AI can do with City by Month
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “list_cities”: Every city in City by Month's data: slug, profile page, climate kind (station or model estimate).”
“Use “city_month”: One city's climate normals, daylight, rule result and ranks for one month.”
“Use “best_time”: One city: months meeting City by Month's weather rule, near misses, other misses (what fails, by how much), the rule.”
“Use “compare”: 2-5 cities side by side for one month. Station and model-estimate cities are not mixed.”
How secure is the City by Month MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how City by Month holds up.
Security grade A
gate scanned 4 tools on Nov 11, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by City by Month (citybymonth.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 City by Month adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
