Claude MCP Server Ecosystem

# Claude Code MCP Server Connection Solution ## Problem Analysis Based on research from Stack Overflow and GitHub issues, the main problems are: 1. **Tool name validation errors** - API Error 400 with tool names not matching pattern `^[a-zA-Z0-9_-]{1,64}$` 2. **Protocol version validation issues** - stdio servers missing protocolVersion field 3. **Path inconsistencies** - mixing npx with direct node paths causes failures 4. **Configuration conflicts** - multiple config files with different server definitions ## Root Cause Your enhanced memory server tools have names that follow the correct pattern, but the connection is failing due to configuration inconsistencies and path issues. ## Solution ### 1. Use the Fixed Configuration Replace your Claude Code configuration with: ```bash cp /Users/robertlee/GitHubProjects/Claude_MCPServer/config/claude-code/claude_code_config_fixed.json ~/.config/claude-code/claude_code_config.json ``` ### 2. Key Fixes Applied: - **Consistent Node Paths**: All commands use full node/npx paths from nvm - **Tool Name Validation**: Enhanced memory server already has compliant tool names - **Environment Variables**: Added NODE_ENV for production stability - **Working Directory**: Specified cwd for tsx execution ### 3. Server Details: #### Enhanced Memory Server (Primary) - **Tools**: `store_enhanced_memory`, `retrieve_optimized_context`, `get_optimization_stats` - **Features**: 6 optimization techniques including context compression and sliding window - **Path**: Uses npx tsx for TypeScript execution #### Memory Simple User (Backup) - **Tools**: Basic memory operations - **Compatibility**: Works with existing Claude Desktop setup #### Sequential Thinking - **Official MCP Server**: Proven to work with Claude Code - **Installation**: Uses npx with official package ### 4. Troubleshooting Commands: Test individual servers: ```bash # Test enhanced memory (should timeout waiting for stdio - this is correct) timeout 5s npx tsx /Users/robertlee/GitHubProjects/Claude_MCPServer/servers/memory/src/enhanced-memory-final.ts # Test simple memory timeout 5s node /Users/robertlee/GitHubProjects/Claude_MCPServer/mcp/memory/simple-server.js # Test sequential thinking timeout 5s npx -y @modelcontextprotocol/server-sequential-thinking ``` ### 5. Verification Steps: 1. Stop any running MCP processes: `pkill -f "simple-server\|enhanced-memory"` 2. Replace config file with fixed version 3. Restart Claude Code 4. Check `mcp` command shows all 3 servers as connected ## Edge Cases Addressed: - **Node version conflicts**: Uses specific nvm node path - **TypeScript execution**: Uses npx tsx instead of direct node - **Environment isolation**: Separate env vars for each server - **Path resolution**: Absolute paths prevent working directory issues ## Expected Result: All 3 MCP servers should connect successfully with Claude Code, giving you access to: - Enhanced memory with 6 optimization techniques - Simple memory for basic operations - Sequential thinking for reasoning chains
