What can you grow where you live?
The 2023 USDA Plant Hardiness Zone Map for every US ZIP code, exposed as structured WebMCP tools. Search it yourself, or let your agent look up zones, compare locations, and build a garden plan with you on this page.
Plants for your zone
Pick a ZIP to filter 50+ common vegetables, herbs, peppers and fruit.
Agent tools on this page
Registered with document.modelContext.registerTool(). Open this page in the ChatGPT desktop browser or Chrome with
chrome://flags/#enable-webmcp-testing and ask your agent things like
"What zone is 80301 and what peppers can I grow?"
JSON API for backend agents
The same data as a plain HTTP API, so server-side agents and other apps can use hardiness zones as a primitive.
