🔒 Safety & Enterprise Features

CRITICAL SAFETY CONTROLS: This MCP server can perform write operations on NetBox data:

• ✅ Idempotent Operations: All write tools are idempotent by design

🏗️ Architecture Highlights

Revolutionary Dual-Tool Pattern

• Fundamental LLM Architecture: Every NetBox domain implements both "info" tools (detailed single-object retrieval) and "list_all" tools (bulk discovery/exploration)

• Comprehensive Filtering: All list tools support filtering by site, tenant, status, and domain-specific criteria

• Summary Statistics: Rich aggregate statistics, breakdowns, and utilization metrics for operational insight

• Cross-Domain Integration: Tools bridge DCIM, IPAM, and Tenancy domains with relationship tracking

Revolutionary Self-Describing Server

• @mcp_tool Decorator: Automatic function inspection and metadata generation

• Plugin Architecture: Modular tools/ subpackage with automatic discovery

• Registry Bridge Pattern: Seamless connection between internal registry and FastMCP interface

• Dependency Injection: Clean separation using FastAPI's Depends() system

• REST API Endpoints: /api/v1/tools, /api/v1/execute, /api/v1/status
