## Quick start

### MCP server (Claude Desktop, Cursor, etc.)

```sh
npx @cropgraph/mcp
```

See [`packages/mcp/README.md`](./packages/mcp/README.md) for client config.

### CLI

```sh
npx cropgraph zone --lat 48.118 --lng -123.43
npx cropgraph companions tomato
npx cropgraph planting --zone 8b --climate maritime
npx cropgraph succession lettuce --zone 8b --climate maritime
npx cropgraph pests tomato
npx cropgraph pest-intel tomato-hornworm --plant tomato
npx cropgraph beneficial seven-spotted-ladybug
```

### Library

```sh
npm install @cropgraph/core
```

```ts
import {
  getHardinessZone,
  getCompanions,
  getPlantingPlan,
  getSuccessionPlan,
} from "@cropgraph/core";

getHardinessZone(48.118, -123.43);   // "8b"
getCompanions("tomato");             // 18 entries
getPlantingPlan({ zone: "8b", climateType: "maritime" });
getSuccessionPlan({ slug: "lettuce-leaf", zone, climateType: "maritime" });
```

## Data

| Asset | Count | Notes |
|-------|-------|-------|
| Crop calendar | 5,006 entries | 14 categories (vegetable, herb, fruit, flower, cover-crop, root, legume, grain, mushroom, native, medicinal, fiber, forage, sprout). Frost-anchored windows; 120 entries carry climate modifiers across 6 climate types |
| Companion relationships | 1,004 | 510 beneficial, 95 antagonist, 12 mechanism categories |
| Growing degree days | 120 models | Cultivar-specific GDD ranges, base temperatures, NOAA Climate Normals harvest prediction |
| Rotation families | 12 | Nightshades, brassicas, cucurbits, alliums, legumes, umbellifers, grasses, amaranthaceae, composites, mints, malvaceae, miscellaneous. Every calendar slug mapped. |
| Succession chains | 33 | Greens, roots, legumes, brassicas, cucurbits, herbs, flowers, cover crops. Frost-anchored phases with per-climate notes. |
| Pest/disease associations | 506 | Crop-to-pest edges with diagnostic symptoms, organic management, prevention, and regions. OMRI-listed management only. |
| Beneficial insects | 200 entries | Predators (62), parasitoids (40), pollinators (50), decomposers (29), microbial controls (22). Prey and attractant cross-references; composite "now what?" intelligence layer with hand-authored notes for the top 40 pest slugs. |
| USDA hardiness zones | 40,283 ZIPs | PRISM 2023 + waldoj/frostline centroids, offline lookup |
| Climate classifier | 6 types | Maritime, mediterranean, continental, humid subtropical, arid, semi-arid |
