DSSAT MCP Server — Claude Desktop Integration

Connect Claude Desktop to a DSSAT MCP server to download inputs, run experiments, and collect outputs—directly from a chat.

Quick Start

1) Install Claude Desktop

• Windows: Download and install the official Windows app, then sign in.

• Ubuntu/Debian (community build): Use the community repo aaddrick/claude-desktop-debian to install a .deb/.AppImage, or build from source:

  git clone https://github.com/aaddrick/claude-desktop-debian.git
  cd claude-desktop-debian
  ./build.sh
  sudo dpkg -i ./claude-desktop_*.deb
  
  # If you encounter dependency issues:
  sudo apt --fix-broken install
  

Config paths:

• Windows: %APPDATA%\Claude\claude_desktop_config.json

• Linux: ~/.config/Claude/claude_desktop_config.json

  Tip: You can also open the config from Settings → Developer → Edit Config in Claude Desktop.

2) Add MCP configuration

Paste the JSON below into your config file. Replace only the token value; keep everything else identical. Tokens will be provided upon request.

{
  "mcpServers": {
    "dssat": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://dev.mcp.crops.qvantum.scio.services/mcp",
        "--allow-http",
        "--header",
        "Authorization: Bearer ${ACCESS_TOKEN}}"
      ],
      "env": {
        "ACCESS_TOKEN": "<REPLACE_WITH_YOUR_ACCESS_TOKEN>"
      }
    }
  }
}

If your config invokes npx, ensure Node.js and npm are installed.

3) Use it from Claude Desktop

• Restart Claude Desktop (or reload the developer config).
• Open a new chat. Claude Desktop will automatically discover the MCP server and list available tools.
• Use the example prompt below to run a typical DSSAT workflow.

Tools (high-level description)

• download_files_from_s3 — Download DSSAT input files (e.g., SOIL.SOL, *.WTH, *.MZX) from S3 into a local working folder and verify presence.
• run_dssat_experiment — Run DSSAT using the specified experiment file (FileX) inside the working folder and capture logs/summary.
• upload_and_collect_output_files — Archive the working folder, upload to S3, return a presigned URL for outputs, and perform cleanup.

Example Prompt (paste in Claude Desktop)

I want to run a DSSAT experiment. Check the list of tools to find the correct tool input format. First download and save to folder CUSTOM_EXPERIMENT the following files from S3: SOIL.SOL, UFGA8201.WTH, UFGA8201.MZX. Next execute the experiment with the experiment file UFGA8201.MZX. Then, upload the file to S3 in order to collect the output files.
