WebMCP is a JavaScript interface designed specifically for web developers to expose their web application functionality as "tools." These tools consist of JavaScript functions accompanied by natural language descriptions and structured schemas, enabling AI agents, browser assistants, and assistive technologies to interact with web applications seamlessly.

The key capability of WebMCP is allowing developers to define tools that AI agents can invoke. These tools maintain structured schemas and natural language descriptions, facilitating clear communication between the application and AI systems. The interface supports collaborative workflows where users and agents work together within the same web interface.

WebMCP enables collaborative workflows by maintaining shared context and user control while leveraging existing application logic. This approach ensures that AI agents can operate within web applications without disrupting the user experience or requiring significant changes to the underlying codebase.

The primary benefit is enabling AI agents to access web app functionality through standardized interfaces. Use cases include browser assistants that can perform tasks within web applications and assistive technologies that help users navigate and interact with web interfaces more effectively.

WebMCP targets web developers who want to integrate AI capabilities into their applications. It functions as a developer tool that bridges web applications with AI systems through JavaScript interfaces, making it particularly valuable for projects involving AI agents and automation.
