MCP-Chinese-Getting-Started-Guide

Least-privilege permissions

• Restrict the MCP connector to only the specific data sources and functions it actually needs—don't give it access to your entire network or all databases just because it's easier
• Use read-only access when the connector only needs to retrieve information, and avoid granting unnecessary administrative rights
• Create separate connector instances for different teams or projects rather than sharing a single one with broad permissions across your organization

Network isolation

• Run the MCP connector in a separate, confined environment (a "sandbox") that cannot directly access other sensitive systems unless specifically needed
• Limit outbound connections—the connector should only communicate with approved external services and IP addresses, blocking everything else by default
• Use encrypted connections (HTTPS/TLS) for all communication between the connector and your systems to prevent eavesdropping

Monitoring

• Log all activities the connector performs, including what data it accesses and commands it executes, and regularly review these logs for unusual behavior
• Set up alerts for suspicious patterns like accessing data outside normal business hours, unusually large data transfers, or repeated failed authentication attempts
• Track which tutorial code snippets or external libraries the connector is actually using, and check vendor security notices when updates become available

Red flags to watch for

• Using code directly copied from tutorial examples without having a security expert review it for credential leaks, hard-coded secrets, or unvalidated user inputs
• Allowing the connector to automatically update itself or load code from sources not independently verified by your team
• Weak security in dependent libraries (third-party tools the connector relies on)—if tutorials reference outdated or unmaintained projects, question whether they're still safe to use
