CropGraph

Commercial agricultural intelligence. Curated data, MCP server, and CLI for crop calendars, companion planting, crop rotation, succession planting, pest and disease management, USDA hardiness zones, and climate classification.

Packages

Package

What

@cropgraph/core

Crop calendar (5,006 entries across 14 categories), 1,004 companion relationships, rotation families, succession chains, pest/disease associations, 200 beneficial insects across 5 categories with composite pest intelligence, 120 growing degree day models, USDA zones, climate types. Pure TypeScript, offline.

@cropgraph/mcp

Model Context Protocol server (stdio). Eighteen garden-planning tools for AI agents.

cropgraph

Command-line interface. Subcommands for zones, planting, crop lookup, companions, rotation, succession, pests, pest-detail, pest-intel, beneficials.

Related MCP server: plant-intel-mcp

Quick start

MCP server (Claude Desktop, Cursor, etc.)

npx @cropgraph/mcp

See packages/mcp/README.md for client config.

CLI

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

npm install @cropgraph/core
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" });

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

    Enables AI agents to perform exact, reproducible mechanical computation — text diffing, hashing, JSON querying, calendar arithmetic, deadline-bounded regex extraction, CSV parsing, similarity scoring, unit and base conversion — instead of relying on probabilistic guessing. Runs dependency-free, read-only and offline over stdio, with schema validation and hard caps on every operation so no call can hang the client.

    Gives AI agents a searchable catalog of over 15,000 documented tools, commands and functions across fourteen engineering and design applications, plus headless automation adapters that run the installed software in batch/script mode and return structured JSON. Also provides a timezone-aware time tool and an optional live documentation search, with local-only networking and an internet-tools kill switch by default.
