CropGraph is an MCP server that exposes crop, companion, pest, rotation, soil, GDD, and pest-intelligence data to your coding agent.

About

CropGraph MCP packages agricultural decision support—crops, companion planting, pests, crop rotation, soil context, growing degree days, and pest intelligence—for agents via the @cropgraph/mcp npm server on stdio. developers in ag-tech, gardening SaaS, or educational content use it when research questions outpace static docs: which companions reduce pest pressure, how rotation rules apply, or what GDD implies for a season plan. It is domain data exposed as MCP tools, not a farm management ERP. After registration, the assistant can reason over structured agronomy knowledge while you validate scope or embed summaries in features. Niche but deep for anyone shipping grower-facing agents without rebuilding a crop knowledge graph from scratch.

What it does

Give your agent agronomy reference—companions, pests, rotation, soil, GDD, and pest intelligence—for farm apps, content products, or ag-tech prototypes.

Who is it for?

Best when you're prototyping grower assistants, garden planners, or pest-alert content and want agronomy MCP tools on stdio.

Skip if: Large commercial farm ERP replacements, real-time sensor IoT platforms, or developers with zero agriculture domain interest.

What you get

After installing @cropgraph/mcp, your agent can pull agronomy and pest intelligence into research notes, scopes, and integration-backed features.

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.
