MCP Best Practices

• Don't install too many servers. Every tool description eats context.
• Scope servers: --scope user for universal, .mcp.json for project-specific.
• Only install servers you trust. They can read files, run code, make API calls.
• Pin versions in production: npx -y package@1.2.3, not just npx -y package.
• Remove or disable servers you're not actively using.
