Alumnx MCP Server

A Model Context Protocol (MCP) server for agricultural intelligence, providing tools for pest/disease lookup, government scheme discovery, and SME knowledge retrieval via semantic search.

---

Features

• Pests & Diseases — RAG-powered lookup for crop pest and disease information
• Government Schemes — RAG-powered search for agriculture-related government schemes by type and state
• SME Divesh — Semantic search over a Pinecone knowledge base (SME-Divesh namespace)
• MCP + REST — Dual interface: MCP protocol (via FastMCP) and plain REST (/callTool)

---

Requirements

• Python 3.9+
• Dependencies (install via pip install -r requirements.txt):

fastmcp
pinecone
sentence-transformers
python-dotenv
uvicorn
httpx
fastapi

Environment Variables

Create a .env file in the project root with the following variables:

Variable	Required	Description
PESTS_DISEASES_RAG_URL	✅	Base URL of the Pests & Diseases RAG service
GOVT_SCHEMES_RAG_URL	✅	Base URL of the Government Schemes RAG service
PINECONE_API_KEY	✅	API key for Pinecone
PINECONE_INDEX	✅	Name of the Pinecone index to query
RAG_TIMEOUT	❌	HTTP timeout in seconds for RAG calls (default: 30)

Example .env:

PESTS_DISEASES_RAG_URL= ___URL__
GOVT_SCHEMES_RAG_URL= __URL__
PINECONE_API_KEY=your-pinecone-api-key
PINECONE_INDEX=your-index-name
RAG_TIMEOUT=30

Running the Server

python alumnx_mcp_server.py

The server starts on port 9000 by default.

Endpoint	Description
/mcp	MCP protocol endpoint (FastMCP)
/callTool	REST tool call endpoint
/list-tools	Lists all available tools
/health	Health check

MCP Tools

pests_and_diseases

Query the RAG system for information about pests and diseases affecting crops.

Parameter	Type	Required	Default	Description
pest_name	string	✅	—	Name of the pest or disease
crop	string	❌	"General"	Crop affected by the pest or disease

Example response:

{
  "status": "success",
  "information": "...",
  "sources": ["..."]
}

---

govt_schemes

Query the RAG system for government schemes related to agriculture.

Parameter	Type	Required	Default	Description
scheme_type	string	✅	—	Type or topic of the scheme
state	string	❌	"All India"	State for which to retrieve schemes

Example response:

{
  "status": "success",
  "information": "...",
  "sources": ["..."]
}

---

sme_divesh

Semantic search over the SME-Divesh Pinecone namespace using all-MiniLM-L6-v2 embeddings.

Parameter	Type	Required	Default	Description
query	string	✅	—	The search query
top_k	integer	❌	5	Number of top results to return

Example response:

{
  "status": "success",
  "query": "crop irrigation techniques",
  "results": [
    {
      "score": 0.91,
      "text": "...",
      "source": "...",
      "chunk_index": 2
    }
  ]
}

---

REST API Usage

All tools are also callable via the /callTool POST endpoint:

curl -X POST http://localhost:9000/callTool \
  -H "Content-Type: application/json" \
  -d '{
    "name": "pests_and_diseases",
    "arguments": {
      "pest_name": "aphids",
      "crop": "wheat"
    }
  }'
