risk identification

Direct operation of web pages by AI assistants may pose security risks such as privacy leakage and unauthorized access.

WebMCP has multiple security protections built in:

Browser Sandbox Isolation: Limit all actions to the current page session
Authority Succession Mechanism: AI has only the permissions that the current user has authenticated through the browser
Input validation system: force parameter validation with tools like zod

Ensure that the web page's own authentication mechanism (e.g. OAuth 2.0) is sound
Strictly define the parameter format and value range of the tool
Limit the frequency of invocation of sensitive operations
List of tools registered for regular audits

The solution reduces security risks to a manageable level with a browser-native security model and strict development specifications.
