Least-privilege permissions

• Run the MCP connector with minimal scopes; restrict agent access to only required file paths and APIs
• Use dedicated service accounts with read-only permissions by default; escalate write access only for specific, audited operations
• If integrating with external services, use short-lived tokens and rotate credentials regularly
• Disable or sandbox any auto-execution features; require explicit user approval for code generation or system modifications

Network isolation

• Deploy the connector in a segmented network or container with egress filtering; whitelist only necessary endpoints
• Disable internet access unless the connector explicitly requires it; if needed, route through an HTTP proxy for logging and filtering
• Avoid connecting directly to production systems during initial deployment; test in isolated staging environments first
• Block outbound connections to untrusted or unknown domains; monitor DNS queries for anomalies

Monitoring

• Log all MCP connector invocations, including inputs, outputs, and errors; retain logs for audit trails
• Alert on unusual patterns: high request volumes, repeated failures, or attempts to access restricted resources
• Monitor for injection attempts in agent prompts (e.g., suspicious keywords, escape sequences, or command syntax)
• Track connector resource consumption (CPU, memory, file I/O) to detect exploitation or unexpected behavior

Red flags to watch for

• Absence of recent package updates or security advisories; verify the library is maintained before production use
• Undocumented data flows or telemetry; audit the code to confirm no sensitive data is transmitted to external services
• Inability to verify educational vs. production intent; contact maintainers to clarify stability guarantees
• Agent inputs that bypass sanitization (e.g., unsanitized file paths, code templates, or prompt parameters); implement strict input validation before passing to the connector
