SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the challenge of dynamically controlling access to tools within a WebMCP environment based on the user's authentication status and roles, ensuring that only appropriate functionalities are exposed.

Core Features & Use Cases

  • Session Inheritance: Leverages the user's existing browser session for authentication, eliminating the need for separate agent logins.
  • Role-Gated Tool Registration: Conditionally registers tools based on user roles (e.g., anonymous, authenticated, admin).
  • Auth State Change Handling: Manages toolset updates during login/logout events.
  • Use Case: In an e-commerce scenario, an agent can automatically provide access to checkout and account management tools only after the user has logged in, while keeping search and product viewing tools available to all users.

Quick Start

Use the webmcp-authentication skill to register tools based on the current user's authentication state.

FAQPage Schema
How do I manage tool access for browser agents based on user authentication?

Tool access for browser agents is managed by conditionally registering tools based on user roles and authentication state. This ensures only appropriate functionalities are exposed, keeping secure tools hidden from unauthenticated sessions.

How does session inheritance work for browser agent authentication?

Session inheritance leverages the user's existing browser session for authentication, eliminating the need for separate agent logins. The agent inherits the current cookie-based authentication state to interact contextually on behalf of the user.

How do I handle auth state changes like login and logout during an agent session?

Auth state changes are handled by dynamically managing toolset updates during login and logout events. The available tools are automatically adjusted to match the user's new role, ensuring continuous access control.

Can I use role-based access control to conditionally expose tools in a web application?

Yes, role-gated tool registration conditionally exposes tools based on user roles such as anonymous, authenticated, or admin. This allows you to provide role-specific functionalities, like account management tools only for logged-in users.

What is the best way to secure agent interactions in a WebMCP environment?

Securing agent interactions in a WebMCP environment is best achieved by implementing cookie-based authentication and role-gated tool registration. This manages tool availability based on user session inheritance for secure interactions.

Does WebMCP authentication support conditional tool exposure for anonymous and admin users?

Yes, conditional tool exposure supports differentiating between anonymous, authenticated, and admin users. It dynamically registers tools based on the current user's role, ensuring only authorized functionalities are available to each user type.
