🔧 MCP Installation Deep Merge Fix

This release addresses a critical issue with MCP (Model Context Protocol) server installation that was overwriting existing configurations.

🐛 Bug Fixes

MCP Installation Overwriting Fix

• Fixed individual MCP installations (--mcp=<name>) overwriting existing .mcp.json configurations
• Implemented deep merge logic specifically for mcpServers key to preserve existing MCP entries
• Ensured sequential MCP installations properly accumulate without data loss

🔧 Technical Details

Problem: When installing MCPs individually, the shallow merge behavior was overwriting the entire mcpServers object instead of merging individual MCP configurations.

Solution: Added deep merge logic that preserves existing MCP server configurations while adding new ones:

// Deep merge mcpServers specifically to avoid overwriting existing servers
if (existingConfig.mcpServers && mcpConfig.mcpServers) {
  mergedConfig.mcpServers = {
    ...existingConfig.mcpServers,
    ...mcpConfig.mcpServers
  };
}

🧪 Verification

✅ Multiple MCP Installation Test:

# Install first MCP
npx claude-code-templates@latest --mcp=memory-integration --yes

# Install second MCP (preserves first)
npx claude-code-templates@latest --mcp=filesystem-access --yes

# Result: Both MCPs correctly present in .mcp.json
