WebMCP is designed with security in mind and has the following security features:
- Browser Sandbox Environment: All operations run in the browser's secure sandbox, isolating system resources
- Authority Succession Mechanism: The AI assistant can only perform actions that are allowed by the user's current session permissions
- authentication integration: directly utilize the authentication mechanisms (e.g., cookies/session tokens) already available on the web page, without the need to store additional credentials
- least authority principle (LAP): Developers need to explicitly register each tool and the scope of its permissions
In contrast to traditional AI integration solutions, WebMCP avoids the following common security issues:
- No need to store sensitive information such as API keys on the server
- Does not require users to repeat OAuth authorization
- Does not expand the attack surface of the original system
Developers should take extra care when using it:
- Ensure that the authentication mechanism on the page itself is secure
- Full validation of user input
- Limit tool availability for sensitive operations
This design protects user data and simplifies the security configuration process, making it ideal for application scenarios with high security requirements.
