Remove mcp/node_modules from repository

[junghan0611]

Issue

The mcp/node_modules/ directory is currently tracked in the repository, but it's already listed in .gitignore.

Problem

• node_modules directories should not be committed to git repositories
• They significantly increase repository size
• They can cause issues when cloning/pulling (as seen with deleted files showing in git status)
• Dependencies should be installed via npm install based on package.json

Current .gitignore

# Node.js
node_modules/
mcp/node_modules/
package-lock.json
mcp/package-lock.json

Suggested Fix

# Remove from git tracking while keeping .gitignore entry
git rm -r --cached mcp/node_modules/
git commit -m "chore: remove mcp/node_modules from tracking"

This will:

1. Remove node_modules from the repository
2. Keep the .gitignore rule to prevent future commits
3. Users can run cd mcp && npm install to install dependencies locally
