Overview

A production-grade lead generation system built on:

• MCP Python SDK for protocol-compliant AI services
• Crawl4AI for intelligent web crawling
• AsyncIO for high-concurrency operations

Implements a full lead lifecycle from discovery to enrichment with:

• UUID-based lead tracking
• Multi-source data aggregation
• Smart caching strategies
• Enterprise-grade error handling

Prerequisites

• Python 3.10+
• API Keys:

  export HUNTER_API_KEY="your_key"
  export CLEARBIT_API_KEY="your_key"
  export GOOGLE_CSE_ID="your_id"

RUN apt-get update && apt-get install -y \
    gcc \
    libpython3-dev \
    chromium \
    && rm -rf /var/lib/apt/lists/*

COPY . /app
WORKDIR /app

RUN pip install --no-cache-dir -r requirements.txt
CMD ["python", "-m", "mcp", "run", "lead_server.py"]

Running the Server

Development Mode

mcp dev lead_server.py --reload --port 8080

Production

gunicorn -w 4 -k uvicorn.workers.UvicornWorker lead_server:app

Docker

docker build -t lead-server .
docker run -p 8080:8080 -e HUNTER_API_KEY=your_key lead-server

API Documentation

1. Generate Lead

POST /tools/lead_generation
Content-Type: application/json

{
  "search_terms": "OpenAI"
}

Response:

{
  "lead_id": "550e8400-e29b-41d4-a716-446655440000",
  "status": "pending",
  "estimated_time": 15
}

2. Enrich Lead

POST /tools/data_enrichment
Content-Type: application/json

{
  "lead_id": "550e8400-e29b-41d4-a716-446655440000"
}

3. Monitor Leads

GET /tools/lead_maintenance

---

Examples

Python Client

from mcp.client import Client

async with Client() as client:
    # Generate lead
    lead = await client.call_tool(
        "lead_generation",
        {"search_terms": "Anthropic"}
    )
    
    # Enrich with all services
    enriched = await client.call_tool(
        "data_enrichment",
        {"lead_id": lead['lead_id']}
    )
    
    # Get full lead data
    status = await client.call_tool(
        "lead_status",
        {"lead_id": lead['lead_id']}
    )

cURL

# Generate lead
curl -X POST http://localhost:8080/tools/lead_generation \
  -H "Content-Type: application/json" \
  -d '{"search_terms": "Cohere AI"}'

---

Advanced Configuration

Caching Strategies

from aiocache import Cache

# Configure Redis cluster
Cache.from_url(
    "redis://cluster-node1:6379/0",
    timeout=10,
    retry=True,
    retry_timeout=2
)

Rate Limiting

from mcp.server.middleware import RateLimiter

mcp.add_middleware(
    RateLimiter(
        rules={
            "lead_generation": "100/1m",
            "data_enrichment": "50/1m"
        }
    )
)

---

Troubleshooting

Error	Solution
403 Forbidden from Google	Rotate IPs or use official CSE API
429 Too Many Requests	Implement exponential backoff
Playwright Timeout	Increase scraping.timeout in config
Cache Miss	Verify Redis connection and TTL settings
