netcfg-agent-mcp

Serveur MCP standalone pour netcfg-agent. Expose le code metier netcfg (inventaire Visio, preview deploy, topologie, terminal SSH live multi-vendor) comme tools MCP consommables par n importe quel client compatible (Claude Desktop, Gemini CLI 0.38+, Roo Code, Cline, Cursor, etc.).

Positionnement

Ce repo est le 4eme de la famille netcfg-agent :

Il n est pas un sous-ensemble fonctionnel du master mais une couche d exposition protocolaire par-dessus. Il depend du master pour le code metier.

Installation via binaire (sans Python)

Les releases GitHub fournissent le binaire autonome netcfg-agent-mcp.exe (Windows x64, ~130 MB) qui embarque :

  • Python 3.12 runtime
  • Le code netcfg-agent master (tous les tools metier)
  • mcp SDK + FastAPI + uvicorn + asyncssh + pyte
  • Les templates vendor et la demo enterprise_network.vsdx

Telechargez depuis les releases et lancez directement :

netcfg-agent-mcp.exe --version
netcfg-agent-mcp.exe serve --transport http

Installation (Python)

pip install netcfg-agent-mcp
REM tire netcfg-agent[terminal] (code metier + terminal PTY SSH)

netcfg-agent-mcp --version
netcfg-agent-mcp --help

Developpement : depuis un clone, pip install -e ".[dev]".

Authentification

  • Bearer token local genere au premier run, stocke dans %USERPROFILE%\.netcfg-agent-mcp\token (ACL user-only)
  • Permissions heritees de LaForge si hub dispo (authority_status)
  • Fallback : lock SQLite local hash-chainee (via db_waldb du master)

Historique decisions

Voir ROADMAP_MCP_FORK.md dans le repo master pour l historique complet des decisions d architecture.

Points cles :

  • Phase 1 (actuelle) : dep directe LaForge via pyproject (Scenario 2)
  • Phase 2 (differee) : extraction laforge-mcp-core (Scenario 3)
  • Budget binaire PyInstaller : < 180 MB
  • Flag --standalone : desactive tous hooks LaForge
