MCP connection security measures
The following security policies should be adopted when using the MCP server:
- minimization of authority principle (MA principle): Configure access permissions independently for each server, without the use of highly privileged accounts such as root/admin
- Localized operation: Sensitive data servers are recommended to run in an intranet environment without exposing ports.
- encrypted transmission: Prefer server versions that support HTTPS/WSS protocols
Specific security practices
- Authentication: Configure API keys or OAuth authentication for the server
- Access control: IP whitelisting via server config file
- Audit Logging: Enable the access logging feature of the server to periodically check for abnormal requests
- Data desensitization: filtering of returned results by sensitive fields at the server level
The MCP protocol itself is designed with end-to-end encryption and all data transmissions are encrypted. It is recommended to update the server version monthly for the latest security patches.
