# MCP Security & Best Practices

## Authentication & Authorization

When integrating MCP servers with Agent-CoreX, ensure proper authentication mechanisms are in place.

### API Key Management

* Never hardcode API keys in your MCP server implementation
* Use environment variables for sensitive credentials
* Rotate API keys regularly
* Revoke keys when MCP server access is no longer needed

### Token Scoping

Limit token permissions to the minimum required scope for your MCP server operations.

## Data Privacy

### Data in Transit

* All MCP server communication with Agent-CoreX uses HTTPS/TLS
* Encrypt sensitive data before passing through MCP tools
* Validate SSL certificates for external server connections

### Data at Rest

* Consider encrypting sensitive data stored in your MCP server
* Implement proper access controls for your server endpoints
* Follow your organization's data retention policies

## Server Validation

### Input Validation

* Validate all inputs received from Agent-CoreX
* Implement rate limiting on your MCP server endpoints
* Sanitize outputs before returning to Agent-CoreX

### Error Handling

* Don't expose sensitive information in error messages
* Log security events appropriately
* Implement proper exception handling

## Compliance

Ensure your MCP server implementation complies with:

* GDPR for EU user data
* CCPA for California residents
* Industry-specific regulations (HIPAA, PCI-DSS, etc.)
* Your organization's security policies

## Security Monitoring

* Monitor MCP server logs for suspicious activity
* Set up alerts for authentication failures
* Regularly audit access to your MCP server
* Review usage patterns for anomalies
