MCP PVE

MCP server for Proxmox VE. Manage virtual machines, containers, storage, networking, and clusters through natural language in Cursor, Claude Code, and Claude Desktop.

Features

• 121 tools across 12 categories covering the Proxmox VE REST API
• Three access tiers (read-only, read-execute, full) for granular control
• Category filtering via PVE_CATEGORIES to expose only the tools you need
• Zero HTTP dependencies -- uses native fetch (Node 22+)
• Self-signed cert support via PVE_VERIFY_SSL=false
• Docker images for linux/amd64 and linux/arm64 on GHCR
• Remote MCP via HTTP transport (MCP_TRANSPORT=http) using the Streamable HTTP protocol
• TypeScript/ESM with full type safety

API Compatibility

Tested with Proxmox VE 9.2.4.

Quick Start

Run the server directly with npx:

PVE_BASE_URL="https://pve.example.com:8006" \
PVE_TOKEN_ID="root@pam!mcp" \
PVE_TOKEN_SECRET="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" \
npx -y @samik081/mcp-pve

The server validates your PVE connection on startup and fails immediately with a clear error if credentials are missing or invalid.

Docker

Run with Docker (stdio transport, same as npx):

docker run --rm -i \
  -e PVE_BASE_URL=https://pve.example.com:8006 \
  -e PVE_TOKEN_ID=root@pam!mcp \
  -e PVE_TOKEN_SECRET=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx \
  -e PVE_VERIFY_SSL=false \
  ghcr.io/samik081/mcp-pve

To run as a remote MCP server with HTTP transport:

docker run -d -p 3000:3000 \
  -e MCP_TRANSPORT=http \
  -e PVE_BASE_URL=https://pve.example.com:8006 \
  -e PVE_TOKEN_ID=root@pam!mcp \
  -e PVE_TOKEN_SECRET=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx \
  -e PVE_VERIFY_SSL=false \
  ghcr.io/samik081/mcp-pve

The MCP endpoint is available at http://localhost:3000 and a health check at http://localhost:3000/health.

Configuration

Claude Code CLI (recommended):

# Using npx
claude mcp add --transport stdio pve \
  --env PVE_BASE_URL=https://pve.example.com:8006 \
  --env PVE_TOKEN_ID=root@pam!mcp \
  --env PVE_TOKEN_SECRET=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx \
  --env PVE_VERIFY_SSL=false \
  -- npx -y @samik081/mcp-pve

# Using Docker
claude mcp add --transport stdio pve \
  --env PVE_BASE_URL=https://pve.example.com:8006 \
  --env PVE_TOKEN_ID=root@pam!mcp \
  --env PVE_TOKEN_SECRET=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx \
  --env PVE_VERIFY_SSL=false \
  -- docker run --rm -i ghcr.io/samik081/mcp-pve

# Using remote HTTP (connect to a running Docker container or HTTP server)
claude mcp add --transport http pve http://localhost:3000

JSON config (works with Claude Code .mcp.json, Claude Desktop claude_desktop_config.json, Cursor .cursor/mcp.json):

{
  "mcpServers": {
    "pve": {
      "command": "npx",
      "args": ["-y", "@samik081/mcp-pve"],
      "env": {
        "PVE_BASE_URL": "https://pve.example.com:8006",
        "PVE_TOKEN_ID": "root@pam!mcp",
        "PVE_TOKEN_SECRET": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "PVE_VERIFY_SSL": "false"
      }
    }
  }
}

Docker (stdio):

{
  "mcpServers": {
    "pve": {
      "command": "docker",
      "args": ["run", "--rm", "-i",
        "-e", "PVE_BASE_URL=https://pve.example.com:8006",
        "-e", "PVE_TOKEN_ID=root@pam!mcp",
        "-e", "PVE_TOKEN_SECRET=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "-e", "PVE_VERIFY_SSL=false",
        "ghcr.io/samik081/mcp-pve"
      ]
    }
  }
}

Remote MCP (connect to a running Docker container or HTTP server):

{
  "mcpServers": {
    "pve": {
      "type": "streamable-http",
      "url": "http://localhost:3000"
    }
  }
}

Access Tiers

Control which tools are available using the PVE_ACCESS_TIER environment variable:

Tier details:

• full: All 121 tools. Includes creating/deleting VMs, containers, storage, users, firewall rules, and more.
• read-execute: 76 tools. All read tools plus power actions (start, stop, migrate), bulk guest actions, OCI image pull, backup execution, and task management.
• read-only: 54 tools. List, get, status, and log tools only. No state changes.

Tools that are not available in your tier are not registered with the MCP server. They will not appear in your AI tool's tool list, keeping the context clean.

Environment Variables

Create API tokens in the PVE UI under Datacenter > Permissions > API Tokens. Make sure to uncheck "Privilege Separation" if you want the token to inherit the user's full permissions.

Available Categories

nodes, qemu, lxc, storage, cluster, access, pools, network, firewall, backup, tasks, ha

Tools

mcp-pve provides 121 tools organized by category. Each tool's Access column shows the minimum tier required: read-only (available in all tiers), read-execute (requires read-execute or full), or full (requires full tier only). The Hints column shows tool behavior: read-only (no state changes), destructive (modifies existing state), idempotent (same result if called twice).

Verify It Works

After configuring your MCP client, ask your AI assistant:

"What nodes are in my Proxmox cluster?"

If the connection is working, the assistant will call pve_list_nodes and return your nodes with their current status.

Usage Examples

Once configured, ask your AI tool questions in natural language:

• "List all VMs on node pve1" -- calls pve_list_qemu_vms to show VMs with their status, CPU, and memory usage.

• "What's the status of VM 100?" -- calls pve_get_qemu_status to show real-time resource utilization.

• "Start container 200 on pve1" -- calls pve_start_lxc_container to start the container and returns the task UPID.

• "Create a snapshot of VM 100 called pre-upgrade" -- calls pve_create_qemu_snapshot to create a snapshot before changes.

• "Show me the cluster resources" -- calls pve_list_cluster_resources to show all VMs, containers, storage, and nodes.

• "Migrate VM 100 to node pve2" -- calls pve_migrate_qemu_vm to live-migrate the VM to another node.

• "Shut down VMs 103, 104 and 105 in parallel" -- calls pve_bulk_shutdown_guests to shut down multiple guests cluster-wide in a single request.

Troubleshooting

Connection refused / ECONNREFUSED

Check that PVE_BASE_URL is correct and includes the port (default: 8006). Ensure the PVE host is reachable from where the MCP server is running.

SSL certificate errors

If your PVE instance uses a self-signed certificate, set PVE_VERIFY_SSL=false. This disables TLS verification for all requests.

Tools not showing up

Check your access tier setting. In read-only mode, only 54 tools are registered. In read-execute mode, 76 tools are registered. Use full (or omit PVE_ACCESS_TIER) for all 121 tools. Check PVE_CATEGORIES -- only tools in listed categories are registered. Also verify the server started without errors by checking stderr output.
