What it does

US Grow Zones is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

From the publisher's description, Electra Index matched it to one capability: calendar management. That makes it a candidate for tasks such as plan a content calendar or book appointments online.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

4 tools offered to AI assistants

  • 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.
  • 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.
  • 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_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.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
