🚀 Project Overview & Problem Statement

Traditional agricultural automation systems rely on rigid, static threshold rules (e.g., if moisture < 30%, turn on water). These configurations break down when confronting complex real-world variables, such as ignoring predictive weather APIs or blindly trusting inaccurate rain forecasts while crops actively suffer from dehydration stress.

This project implements an adaptive multi-agent reasoning framework powered by Gemini 2.5 Flash and structured using the Model Context Protocol (MCP). The pipeline evaluates live sensor data, detects logical conflicts between atmospheric forecasts and ground truth metrics, automatically accounts for rain-induced nutrient leaching, and actuates irrigation hardware safely through integrated operational guardrails.

🛠️ Key Concepts Applied

This project demonstrates three core course concepts to satisfy the capstone technical evaluation matrix:

1. Agent / Multi-agent System (ADK): Powered by the google-genai SDK, our agent processes complex telemetry and makes contextual agronomic decisions (balancing temperature, moisture, and weather trends) instead of relying on brittle, hardcoded if/else logic loops.
2. MCP Server Integration: Built a local FastAPI server acting as an MCP host. It standardizes data access by exposing real-time sensor metrics as an MCP Resource stream and standardizes farm hardware control by exposing valve actuators as an executable MCP Tool.
3. Security Features (Deterministic Guardrails): Implemented an operational physical safety gate directly into the pipeline code. If soil moisture exceeds 50% (soggy/wet conditions), the script instantly trips a safety gate, bypassing the LLM entirely to defend against root rot and unnecessary resource spend.
4. Antigravity 2.0 [ MCP Server Resource ] ----> [ Validated Data Schema ] ----> [ Hardware Guardrail ] (Simulated Telemetry) (Moisture, Temp, Forecast, pH) (Max 50% Moisture Check) [ Executable MCP Tool ] <==== [ AI Agent Decision Loop ] <========

🧪 Advanced Agronomic Reasoning: The Leaching Feedback Loop

A standout feature of this agent is its ability to handle multi-variable environmental relationships:

• The Problem: Heavy rainfall washes basic, alkaline nutrients (Calcium, Magnesium) deep into the subsoil, causing permanent chemical changes that lower soil pH (acidification).
• The Agent Solution: If the incoming weather feed signals heavy rain while the physical soil pH drops below 6.0, the agent dynamically calculates a High Leaching Risk. Rather than just managing water, it halts irrigation and triggers a Critical ACUP (Acidic Concentration Update) diagnostic alert, instructing the farmer on soil chemical remediation steps.

⚡ Getting Started & Setup Instructions
1. Install Dependencies
Ensure you are running within an isolated Python virtual environment, then install the required packages:
pip install -r requirements.txt

2. Configure Your Environment Workspace
Set up your Gemini authorization key within your local environment terminal:
export GEMINI_API_KEY="your_actual_gemini_api_key_here"

3. Launch the MCP Server
Start up the FastAPI server to begin exposing live telemetry resource feeds on port 8000:
python -m uvicorn src.mcp_server:app --reload --port 8000

4. Execute the Pipeline Agent
In a separate terminal window, execute the smart agent to run a diagnostics loop and actuate hardware tasks:
python src/agent.py
