v3.3.0

# 🔗 MCP Integration Now Live 🥳

GPT Researcher now supports **Model Context Protocol (MCP)** - connect to specialized data sources alongside web search for comprehensive research.

## Key Features
- **Two-stage intelligent approach**: Auto-selects relevant tools and generates contextual research
- **Hybrid strategies**: Combine web search with MCP servers (`RETRIEVER=tavily,mcp`)
- **Multi-server support**: GitHub, financial APIs, academic databases, custom tools
- **Zero-config optimization**: Works out-of-the-box with sensible defaults

## Quick Start
```python
from gpt_researcher import GPTResearcher
import os

# Enable hybrid research
os.environ["RETRIEVER"] = "tavily,mcp"

researcher = GPTResearcher(
    query="What are the latest React patterns?",
    mcp_configs=[{
        "name": "github",
        "command": "npx",
        "args": ["-y", "@modelcontextprotocol/server-github"],
        "env": {"GITHUB_TOKEN": os.getenv("GITHUB_TOKEN")}
    }]
)

context = await researcher.conduct_research()
report = await researcher.write_report()
```

## Use Cases
- **Code research**: GitHub repos, documentation, technical analysis
- **Financial analysis**: Market data, stock trends, business intelligence  
- **Academic research**: ArXiv papers, research databases
- **Enterprise integration**: Internal systems, compliance workflows
