Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

frost

get_frost_dates

Use this when the user asks for the average last spring frost, first fall frost, or growing season length for a U.S. ZIP code (or a city + state). Returns NOAA 1991-2020 frost dates (10/30/50% probability) and a source link to cite.

planting

get_planting_calendar

Use this when the user asks when to start seeds indoors, transplant, direct sow or plant a fall crop for vegetables at a U.S. ZIP code. Optionally pass one crop; otherwise returns all supported crops. Includes a source link to cite.

what

what_to_plant_now

Use this when the user asks what vegetables they can plant or start now (or on a given date) at a U.S. ZIP code. Returns crops whose planting window is open, plus what opens in the next 30 days, and a source link to cite.

zone

get_zone_by_zip

Use this when the user asks what USDA plant hardiness zone (e.g. 7a) a U.S. ZIP code is in, or the average extreme winter low there. Returns the 2023 USDA zone, temperature range and a source link to cite.

US Grow Zones — questions

Answers built from our own checks of this server.

What can US Grow Zones do?

It exposes 4 tools, read directly from the server on our last check. Among them: get_frost_dates, get_planting_calendar, get_zone_by_zip, what_to_plant_now. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is US Grow Zones working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 200 ms. The bar chart above shows every period we have measured.

How do I connect US Grow Zones?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does US Grow Zones need an API key?

No. US Grow Zones completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is US Grow Zones?

It answers our handshake in 200 ms on average, which is faster than 70% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
