MCP Integration in AI

# MCP enables access to:
- Databases
- APIs  
- Documentation
- External tools

# Configuration in .mcp.json at the project root:
{
  "mcpServers": {
    "database": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-postgres", "postgresql://..."]
    }
  }
}

# Or add one from the CLI: claude mcp add

# Then in Claude:
"Query the users table for active accounts"
"Check the API documentation for endpoints"
