Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account Cropgraph for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

CropGraph is a local MCP server that gives an assistant offline agricultural data and eighteen garden-planning tools for crops, companions, rotation, pests andG

What you can do: Look up crops, planting calendars and USDA hardiness zones by location or zone code, with climate-type modifiers and succession planting chains for staggered harvests. Check companion planting relationships and crop rotation families to plan what grows well together and what to follow in a bed. Retrieve pest and disease associations with diagnostic symptoms, organic management and prevention notes, plus beneficial insect profiles and composite pest intelligence for common pest problems. Query growing degree day models for cultivar-specific harvest prediction.
When to use it: Useful when planning a vegetable garden or small farm: choosing what to plant and when for a given zone and climate, arranging companions and rotations, and diagnosing or preventing pests and diseases. Not a general-purpose tool outside horticultural planning.
Requirements: Runs as a local stdio process, started for example with npx from the npm package @cropgraph/mcp, so Node.js and network access for the initial package download are needed. No authentication, environment variables or headers are declared; the underlying data is described as offline.

Before you install

The README calls the data commercial agricultural intelligence and cites sources per entry; treat recommendations as reference material rather than professional agronomic advice. No credentials, payments or write actions are declared, and the manifest lists no tools, so confirm the actual tool set after connecting.

Installation

In SourceWeft

Open Cropgraph in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
