CropHist

CropHist MCP Server

Natural-language access to 62M fields of crop rotation history for Claude Desktop, Claude Code, ChatGPT / Codex, and any other Model Context Protocol client.

What is MCP?

The Model Context Protocol is an open standard that lets AI assistants call tools safely with structured schemas. Anthropic, OpenAI (ChatGPT / Codex), and a growing ecosystem of agents support it. CropHist exposes 9 tools over MCP, so any MCP-capable AI agent can look up fields, compare years, analyze polygons, and export data — all from plain English prompts.

Quick start — Claude Desktop

Paste into your claude_desktop_config.json:

{
  "mcpServers": {
    "crophist": {
      "command": "npx",
      "args": ["-y", "crophist-mcp"]
    }
  }
}

Restart Claude Desktop, then ask: "What crops were grown near Ames, Iowa, over the last 10 years?"

Quick start — Claude Code

claude mcp add crophist -- npx -y crophist-mcp

Quick start — ChatGPT / Codex & other agents

Any MCP-compatible client works — just point it at the hosted JSON-RPC endpoint:

https://mcp.crophist.com

For clients that want a local stdio process (same as Claude Desktop), run npx -y crophist-mcp.

Remote HTTP mode

The endpoint speaks JSON-RPC 2.0 over POST. 25 free demo calls/day with no signup.

curl -X POST https://mcp.crophist.com \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
