Plantos MCP Server

Model Context Protocol (MCP) server that exposes the Plantos agricultural intelligence API as tools for Claude and other AI assistants.

Overview

This MCP server wraps the Plantos API, allowing AI assistants to:

• Analyze farm locations for optimal crop selection
• Get real-time soil data from SSURGO database
• Fetch current weather data from NOAA
• Access live commodity market prices
• Chat with an agricultural advisor powered by RAG
• Generate economic analysis and farming recommendations

Installation

Prerequisites

• Python 3.10 or higher
• Running Plantos API instance
• API key for Plantos API

Setup

1. Install dependencies:

cd mcp-server
pip install -r requirements.txt

2. Configure environment:

cp .env.example .env
# Edit .env with your settings:
# PLANTOS_API_URL=http://localhost:8000
# PLANTOS_API_KEY=your-api-key-here

3. Test the server:

python src/plantos_mcp_server.py

Integration with Claude Desktop

Add this configuration to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "plantos": {
      "command": "python",
      "args": [
        "/absolute/path/to/plantos/mcp-server/src/plantos_mcp_server.py"
      ],
      "env": {
        "PLANTOS_API_URL": "http://localhost:8000",
        "PLANTOS_API_KEY": "your-api-key-here"
      }
    }
  }
}

Replace /absolute/path/to/plantos/ with the actual path to your installation.

Restart Claude Desktop

After adding the configuration, restart Claude Desktop. You should see the Plantos tools available in the tools menu.

Usage Examples

Example 1: Analyze a Farm Location

Ask Claude: "Analyze the farming potential for coordinates 42.3601, -71.0589"

Claude will use the analyze_farm_location tool and provide:
- Soil analysis
- Weather conditions
- Crop recommendations with predicted yields
- Market prices
- Economic analysis showing expected profits

Example 2: Get Market Insights

Ask Claude: "What are the current prices for corn and soybeans in Iowa?"

Claude will use get_market_data with location context to provide:
- Current spot prices
- Futures prices
- Price trends
- Regional adjustments

Example 3: Chat with Agricultural Advisor

Ask Claude: "What are the best practices for improving soil health in sandy soils?"

Claude will use chat_with_agricultural_advisor to provide:
- Evidence-based recommendations
- Source citations from agricultural research
- Practical implementation steps

Example 4: Complete Farm Planning

Ask Claude: "I'm at 41.8781, -87.6298 and want to maximize profit.
What crops should I plant and what's the expected return?"

Claude will:
1. Use analyze_farm_location to get comprehensive data
2. Use chat_with_agricultural_advisor for strategic advice
3. Synthesize results into actionable recommendations

Testing

1. Start your Plantos API:

cd farming-advisor-api
python run.py

2. Run the MCP server:

cd mcp-server
python src/plantos_mcp_server.py

3. Test in Claude Desktop:
   • Add configuration to claude_desktop_config.json
   • Restart Claude Desktop
   • Try asking Claude to use Plantos tools

Debugging

Enable debug logging:

export MCP_DEBUG=1
python src/plantos_mcp_server.py

Check Claude Desktop logs:

• macOS: ~/Library/Logs/Claude/mcp*.log
• Windows: %APPDATA%\Claude\Logs\mcp*.log

Security

• Store API keys securely in environment variables
• Use HTTPS for production API endpoints
• Implement rate limiting on the API side
• Never commit .env files to version control

Troubleshooting

"Connection refused" errors

• Ensure Plantos API is running on the configured URL
• Check PLANTOS_API_URL in your configuration
• Verify firewall settings

"Authentication failed" errors

• Verify PLANTOS_API_KEY is correct
• Check API key is active in Plantos database
• Ensure API key has proper permissions

Tools not appearing in Claude Desktop

• Verify claude_desktop_config.json syntax
• Check file paths are absolute, not relative
• Restart Claude Desktop completely
• Check Claude Desktop logs for errors

"No data available" responses

• Verify location coordinates are valid
• Check Plantos API has data for that region
• Try a different location (e.g., Iowa farmland)

Performance

• Tool calls typically complete in 2-5 seconds
• Weather data cached by NOAA API
• Market data updates every 15 minutes
• Concurrent tool calls supported

Limitations

• Weather data only available for US locations (NOAA restriction)
• Soil data coverage limited to SSURGO database areas
• Market data may have slight delays (~15 minutes)
• RAG chat requires OpenAI API key or configured LLM

Future Enhancements

• Add real-time weather alerts
• Support international locations
• Add field boundary analysis
• Implement crop rotation planning
• Add pest and disease prediction
• Support multi-year planning
• Add irrigation optimization
