What is the Nandi MCP server?

Connect Nandi to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Open-source MCP server for secure Proxmox node, VM, and LXC operations. The nandi mcp server is what makes that connection.

What the server does

Open source MCP server for Proxmox VE, powered by NANDI Services.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • Backward — compatible aliases such as listNodes, getVMStatus, startVM, stopContainer
  • read-only — Inventory, status, logs, metrics, and non-mutating diagnostics
  • read-execute — Read-only plus selected execution/lifecycle actions
  • full — Create, update, delete, migrate, restore, and admin-level operations
  • PROXMOX_HOST — PROXMOX_USER
  • PROXMOX_REALM — PROXMOX_TOKEN_NAME
  • PROXMOX_TOKEN_SECRET — PROXMOX_SSH_HOST
  • PROXMOX_SSH_USER — PROXMOX_SSH_KEY_PATH
  • PVE_CATEGORIES — PVE_TOOL_BLACKLIST
  • MCP_ALLOWED_HOSTS — MCP_ALLOWED_ORIGINS
  • MCP_RATE_LIMIT_WINDOW_MS — MCP_RATE_LIMIT_MAX
  • MCP_MAX_BODY_SIZE_BYTES — MCP_HEADERS_TIMEOUT_MS

Credentials and setup notes

Configuration is passed through the environment: PROXMOX_HOST, PROXMOX_TOKEN_SECRET, PROXMOX_SSH_HOST, PROXMOX_SSH_KEY_PATH. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Installation

The server ships on npm as nandi-proxmox-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Where it fits

Plenty of monitoring and observability servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Nandi's toolset — Backward, read-only, read-execute and 11 more — is a fair guide to whether it matches your workflow. It is maintained by NANDI-Services; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Nandi.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Nandi to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (Backward, read-only, read-execute, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Nandi directly.
