# Issue #14 Resolution: Claude MCP Connection Fix
## ✅ Problem Resolved
The Claude MCP connection failure has been **successfully resolved**. The issue was with the NPX command mapping for scoped packages.
## 🔍 Root Cause Analysis
1. **NPM Package Mapping**: NPM automatically converts the scoped package `@wangkanai/devops-mcp` to binary name `devops-mcp`
2. **Command Execution**: `npx @wangkanai/devops-mcp` fails because it tries to execute `devops-mcp` command which doesn't exist in that context
3. **Correct Mapping**: The published package maps `@wangkanai/devops-mcp` package → `devops-mcp` binary name
## ✅ Working Solution
### Recommended Command (TESTED & WORKING)
```bash
claude mcp add devops-mcp -- devops-mcp
```
