📋 Best Practices

Package Version Management

When to Use @latest

• Recommended for most users: Ensures you get the latest bug fixes and improvements
• NPM cache issues: Bypasses cache problems that can cause outdated versions
• New installations: Always use @latest for fresh setups
• Troubleshooting: First step when experiencing issues

When to Pin Versions

• Production environments: Consider pinning to specific versions for stability
• CI/CD pipelines: Pin versions to ensure reproducible builds
• Team coordination: Pin when entire team needs same version

Version Management Commands

# Check current version
npx openai-vector-store-mcp@latest --version

# Clear cache and update
npm cache clean --force
npm install -g openai-vector-store-mcp@latest

# Pin to specific version (if needed)
npm install -g openai-vector-store-mcp@1.2.3

Client Configuration Best Practices

Claude Desktop

• Always use @latest in configuration files
• Restart Claude Desktop after configuration changes
• Use environment variables for API keys
• Validate JSON syntax before saving

Claude Code CLI

• Use appropriate scope for your needs:
  • --scope local: Personal development
  • --scope project: Team collaboration
  • --scope user: Cross-project utilities
• Leverage environment variable expansion in .mcp.json
• Use /mcp command to check server status

Roo

• Always include complete alwaysAllow array
• Use exact tool names as documented
• Restart Roo after configuration changes
• Prefer NPM package over Cloudflare Workers for best performance

Troubleshooting Matrix

Issue	Claude Desktop	Claude Code CLI	Roo
Outdated Version	Use @latest in config	claude mcp remove then re-add with @latest	Use @latest in config
Cache Issues	npm cache clean --force	npm cache clean --force	npm cache clean --force
Permission Denied	Check API key in env	Check --env flag	Add tools to alwaysAllow
Server Not Found	Restart client	claude mcp list to verify	Restart Roo
Config Syntax	Validate JSON	cat .mcp.json | python -m json.tool	Validate JSON

Security Best Practices

1. API Key Management

   • Never commit API keys to version control
   • Use environment variables in configuration files
   • Rotate API keys regularly
   • Monitor API usage for unusual activity

2. Configuration Security

   • Keep configuration files in secure locations
   • Use appropriate file permissions
   • Avoid sharing configuration files with embedded keys

3. Network Security

   • All communications use HTTPS/TLS
   • Server inherits your OpenAI API key permissions
   • Consider firewall rules for local development
