@claude 改一下吧，不用这么复杂

// 从构建时注入的版本号获取MCP版本信息
const mcpVersion = process.env.npm_package_version || MCP_VERSION || 'unknown';

MCP version detection simplified ✅

Todo List:

• Read current implementation in mcp/src/utils/tool-wrapper.ts
• Replace complex version detection with simpler approach
• Commit and push changes to PR branch

Changes Made

Successfully simplified the getMcpVersion() function as requested:

• Before: Complex file system operations reading package.json
• After: Simple environment variable approach: process.env.npm_package_version || __MCP_VERSION__ || 'unknown'
• Removed: Unnecessary imports (readFileSync, dirname, join, fileURLToPath)

The new implementation is much cleaner and avoids file system operations, relying on build-time environment variables instead.
