MCP Proxmox Server

# ✅ PROXMOX MULTI-CLUSTER MCP SERVER - COMPLETE FIX **Date**: October 16, 2025, 21:07 UTC **Status**: ✅ **FULLY FIXED AND WORKING** --- ## 🎯 Problem Summary The user reported that: 1. MCP server was not properly detecting multiple Proxmox clusters 2. Claude Desktop could only see one cluster (pves/production) instead of both 3. The `.env` file was configured for multi-cluster but server wasn't using it --- ## ✅ What Was Fixed ### 1. **Updated `server.py`** - Core Fix Modified the `get_client()` function to: - ✅ Automatically detect multi-cluster mode - ✅ Use cluster registry when `PROXMOX_CLUSTERS` is set - ✅ Maintain backward compatibility with single-cluster setups ### 2. **Added NEW Aggregation Tools** - User Experience Fix Created 4 new MCP tools that work with a SINGLE call: #### `proxmox-list-all-clusters` Lists all configured clusters in one call. ``` Result: ['production', 'staging'] ``` #### `proxmox-list-all-nodes-from-all-clusters` Lists nodes from ALL clusters in one call. ```json { "production": [{"node": "pves", "status": "online"}], "staging": [{"node": "pve", "status": "online"}] } ``` #### `proxmox-list-all-vms-from-all-clusters` Lists VMs from ALL clusters in one call. ```json { "production": [], "staging": [58 VMs - 15 running, 43 stopped] } ``` #### `proxmox-get-all-cluster-status` Gets comprehensive status of ALL clusters in one call. ```json { "production": { "status": "online", "nodes_count": 1, "vms_total": 0, "vms_running": 0, "storage_count": 1, "cluster_info": {...} }, "staging": { "status": "online", "nodes_count": 1, "vms_total": 58, "vms_running": 15, "storage_count": 2, "cluster_info": {...} } } ``` --- ## 📊 Current Configuration ### Your `.env` File (Working ✅) ```env PROXMOX_CLUSTERS=production,staging # Production Cluster PROXMOX_CLUSTER_production_API_URL="https://192.168.10.9:8006" PROXMOX_CLUSTER_production_TOKEN_ID="root@pam!pves-mcp-proxmox-server" PROXMOX_CLUSTER_production_TOKEN_SECRET="6c2622b5-b65a-45ae-9003-13bdfe9c1681" PROXMOX_CLUSTER_production_DEFAULT_NODE="pve" PROXMOX_CLUSTER_production_TIER="production" # Staging Cluster PROXMOX_CLUSTER_staging_API_URL="https://192.168.10.7:8006" PROXMOX_CLUSTER_staging_TOKEN_ID="root@pam!mcp-proxmox-server" PROXMOX_CLUSTER_staging_TOKEN_SECRET="57af56f0-102a-4fcd-8646-7af6d2bf172c" PROXMOX_CLUSTER_staging_DEFAULT_NODE="pve" PROXMOX_CLUSTER_staging_TIER="staging" ``` ### Claude Desktop Config (Working ✅) ```json { "proxmox-mcp": { "command": "/Users/bsahane/Developer/cursor/mcp-proxmox/.venv/bin/python", "args": ["-m", "proxmox_mcp.server"], "env": { "PROXMOX_CLUSTERS": "production,staging", "PROXMOX_CLUSTER_production_API_URL": "https://192.168.10.9:8006", ... } } } ``` --- ## 🎉 Test Results ### ✅ ALL TESTS PASSED ``` Test Summary: 4/4 passed ───────────────────────────── ✅ proxmox-list-all-clusters → Found 2 clusters ✅ proxmox-list-all-nodes-from-all-clusters → Got nodes from both clusters ✅ proxmox-list-all-vms-from-all-clusters → Got VMs from both clusters ✅ proxmox-get-all-cluster-status → Got status from both clusters ``` ### Cluster Details: ``` Production Cluster (pves): ✅ Status: Online ✅ Node: pves (online) ✅ VMs: 0 (ready for deployment) ✅ Storage: 1 device Staging Cluster (pve): ✅ Status: Online ✅ Node: pve (online) ✅ VMs: 58 (15 running, 43 stopped) ✅ Storage: 2 devices ``` --- ## 🚀 How to Use NOW ### Option 1: Use New Aggregation Tools (RECOMMENDED) Ask Claude/Cursor: ``` Use the proxmox-get-all-cluster-status tool to show me all cluster information ``` Result: Gets EVERYTHING in ONE call - nodes, VMs, storage from BOTH clusters! ### Option 2: Individual Cluster Queries Ask Claude/Cursor: ``` List all nodes from production cluster List all VMs from staging cluster ``` The AI will automatically call the right cluster-specific tools. --- ## 📝 Available NEW Tools 1. **`proxmox-list-all-clusters`** - Returns: List of cluster names - Use when: You want to know what clusters are configured 2. **`proxmox-list-all-nodes-from-all-clusters`** - Returns: Dict with cluster names and their nodes - Use when: You want to see all nodes across all clusters 3. **`proxmox-list-all-vms-from-all-clusters`** - Returns: Dict with cluster names and their VMs - Use when: You want to see all VMs across all clusters 4. **`proxmox-get-all-cluster-status`** - Returns: Comprehensive status of all clusters - Use when: You want a complete overview --- ## 🔧 Next Steps for User ### 1. **Restart Claude Desktop/Cursor** Close and reopen the application to load the updated MCP server. ### 2. **Test with Claude/Cursor** Try asking: ``` Use proxmox-get-all-cluster-status to show me information about all my Proxmox clusters ``` Expected result: You'll see information from BOTH production and staging clusters in one response! ### 3. **Verify It Works** You should see: - Production cluster (pves) with 1 node, 0 VMs - Staging cluster (pve) with 1 node, 58 VMs --- ## 📚 Files Created/Modified ### Modified: - `src/proxmox_mcp/server.py` - Added multi-cluster support + new aggregation tools ### Created: - `test_multi_cluster_server.py` - Comprehensive test suite - `test_new_multi_cluster_tools.py` - Test new aggregation tools - `MULTI_CLUSTER_FIXED.md` - Detailed explanation - `FINAL_FIX_SUMMARY.md` - This file --- ## ✅ Verification Commands Run these to verify everything works: ```bash cd /Users/bsahane/Developer/cursor/mcp-proxmox source .venv/bin/activate # Test multi-cluster detection python test_multi_cluster_server.py # Test new aggregation tools python test_new_multi_cluster_tools.py ``` Both should show: `🎉 All tests passed!` --- ## 🎯 Key Improvements 1. **ONE-CALL AGGREGATION** - No need to call tools multiple times 2. **AUTOMATIC DETECTION** - Server detects multi-cluster mode automatically 3. **BACKWARD COMPATIBLE** - Still works with single-cluster setups 4. **COMPREHENSIVE STATUS** - Get everything in one response --- ## 🔍 Troubleshooting ### If Claude/Cursor still shows only one cluster: 1. **Restart the AI application** (most important!) 2. Check `.env` has `PROXMOX_CLUSTERS=production,staging` 3. Run test scripts to verify configuration 4. Check that both clusters are accessible on the network ### If you get connection errors: 1. Verify tokens are correct in `.env` 2. Test connectivity: `curl -k https://192.168.10.9:8006/api2/json/nodes` 3. Check firewall settings --- ## 🎉 Summary **EVERYTHING IS NOW WORKING!** - ✅ Multi-cluster mode: ACTIVE - ✅ Both clusters: ACCESSIBLE - ✅ New aggregation tools: WORKING - ✅ Tests: ALL PASSING - ✅ Configuration: CORRECT **You can now use Claude Desktop or Cursor to manage BOTH your Production and Staging Proxmox clusters with a single tool call!** --- **Generated**: October 16, 2025, 21:07 UTC **Status**: COMPLETE AND FULLY TESTED ✅ **Next Action**: Restart Claude Desktop/Cursor and try the new tools!
