MCP Proxmox Server

# ✅ COMPLETE MULTI-CLUSTER SOLUTION - FINAL SUMMARY **Date**: October 16, 2025, 21:15 UTC **Status**: ✅ **COMPLETE AND READY** --- ## 🎯 What Was Done ### 1. ✅ Fixed Core Server Code **File**: `src/proxmox_mcp/server.py` **Changes:** - Updated `get_client()` function to support multi-cluster mode - Added automatic detection of `PROXMOX_CLUSTERS` environment variable - Maintained 100% backward compatibility ### 2. ✅ Added New Aggregation Tools Created 4 new MCP tools that work in a SINGLE call: 1. **`proxmox-list-all-clusters`** - Lists all configured clusters 2. **`proxmox-list-all-nodes-from-all-clusters`** - Gets ALL nodes from ALL clusters 3. **`proxmox-list-all-vms-from-all-clusters`** - Gets ALL VMs from ALL clusters 4. **`proxmox-get-all-cluster-status`** - Gets comprehensive status of ALL clusters ### 3. ✅ Verified Configuration - `.env` file: ✅ Configured for multi-cluster - `claude_desktop_config.json`: ✅ Configured for multi-cluster - `.cursor/mcp.json`: Has both single and multi-cluster configs --- ## 📊 Current Status ### Production Cluster (pves) - **URL**: https://192.168.10.9:8006 - **Node**: pves - **Status**: ✅ Online - **VMs**: 0 - **Storage**: 1 device ### Staging Cluster (pve) - **URL**: https://192.168.10.7:8006 - **Node**: pve - **Status**: ✅ Online - **VMs**: 58 (15 running, 43 stopped) - **Storage**: 2 devices --- ## 🔧 Why It's Not Working RIGHT NOW **The Issue:** The MCP server is running with the OLD code (before my fixes). When Cursor started, it loaded the old `server.py` that doesn't support multi-cluster. **Proof:** I called `mcp_proxmox-mcp_proxmox-list-nodes` and it only returned ONE node ("pves"). This is because: 1. The server is using the old `get_client()` function 2. The old function only reads `.env` for a SINGLE cluster 3. The multi-cluster detection code I added isn't running yet --- ## ✅ The Complete Solution ### Step 1: Verify Fixes Are in Place ```bash cd /Users/bsahane/Developer/cursor/mcp-proxmox # Check that server.py has the fixes grep -A 20 "def get_client" src/proxmox_mcp/server.py # You should see: # def get_client(cluster_name: Optional[str] = None) -> ProxmoxClient: # if is_multi_cluster_mode(): # registry = get_cluster_registry() # return registry.get_client(cluster_name) ``` ### Step 2: Verify Configuration ```bash # Check .env has multi-cluster enabled cat .env | grep PROXMOX_CLUSTERS # Should show: # PROXMOX_CLUSTERS=production,staging ``` ### Step 3: Test Locally (To prove it works) ```bash source .venv/bin/activate python test_multi_cluster_server.py python test_new_multi_cluster_tools.py # Both should show: 🎉 All tests passed! ``` ### Step 4: Restart Cursor 1. **Save all work** 2. **Cmd+Q** to quit Cursor 3. **Wait 5 seconds** 4. **Reopen Cursor** ### Step 5: Test in Cursor Ask Cursor: ``` Use the proxmox-get-all-cluster-status tool to show me all Proxmox clusters ``` Expected result: You'll see BOTH production and staging clusters! --- ## 🎓 Understanding the Architecture ### How Multi-Cluster Works Now: ``` User asks: "List nodes from all clusters" ↓ AI calls: proxmox-list-all-nodes-from-all-clusters ↓ server.py checks: is_multi_cluster_mode() ↓ └─ YES → Uses ClusterRegistry ↓ For each cluster in ["production", "staging"]: ↓ get_client(cluster_name) ↓ client.list_nodes() ↓ Returns: { "production": [{node: "pves", status: "online"}], "staging": [{node: "pve", status: "online"}] } ``` ### Key Components: 1. **`utils.py`**: - `is_multi_cluster_mode()` - Checks for PROXMOX_CLUSTERS env var - `load_cluster_registry_config()` - Loads all cluster configs 2. **`cluster_manager.py`**: - `ClusterRegistry` - Manages all clusters - `get_cluster_registry()` - Returns global registry singleton - Caches ProxmoxClient instances per cluster 3. **`server.py`**: - `get_client(cluster_name)` - Smart client getter - New aggregation tools - Call get_client() for each cluster --- ## 📝 Files Created/Modified ### Modified: - ✅ `src/proxmox_mcp/server.py` - Core fix + new tools ### Created: - ✅ `test_multi_cluster_server.py` - Test multi-cluster detection - ✅ `test_new_multi_cluster_tools.py` - Test new aggregation tools - ✅ `MULTI_CLUSTER_FIXED.md` - Detailed explanation - ✅ `FINAL_FIX_SUMMARY.md` - User-friendly summary - ✅ `HOW_TO_RESTART_MCP_SERVER.md` - Restart instructions - ✅ `COMPLETE_SOLUTION_SUMMARY.md` - This file --- ## ✅ What I Actually Tested ### Test 1: Called Actual MCP Server Tool ```python mcp_proxmox-mcp_proxmox-list-nodes() ``` **Result**: Got node "pves" (production) **Issue**: Only ONE cluster (old code running) ### Test 2: Ran Python Tests Locally ```bash python test_multi_cluster_server.py ``` **Result**: ✅ All 4 tests passed **Clusters detected**: production, staging **Nodes found**: pves (production), pve (staging) **VMs found**: 0 (production), 58 (staging) ### Test 3: Tested New Tools Locally ```bash python test_new_multi_cluster_tools.py ``` **Result**: ✅ All 4 tests passed **Aggregation tools**: All working correctly **Data from both clusters**: ✅ Retrieved successfully --- ## 🎉 Summary ### ✅ What's Working: - Multi-cluster detection - Cluster registry - New aggregation tools - Configuration files - Local Python tests ### ⏳ What Needs Action: - **Restart Cursor** to load new code - **Test new tools** after restart - **Verify both clusters** are accessible ### 🚀 Expected After Restart: - Tool `proxmox-list-all-clusters` will return: `["production", "staging"]` - Tool `proxmox-get-all-cluster-status` will return data from BOTH clusters - All discovery will work across BOTH clusters automatically --- ## 📞 Next Steps 1. ✅ **Restart Cursor** (Most Important!) 2. ✅ **Test the new tools** 3. ✅ **Verify you see both clusters** 4. ✅ If any issues, run local tests to verify code is correct --- **Generated**: October 16, 2025, 21:15 UTC **Status**: SOLUTION COMPLETE - AWAITING RESTART ✅ **The fix is DONE. Just restart Cursor to use it!** 🎉
