About

Persona is a VanillaJS Agent UI Library that helps developers create agentic front-end experiences for the web in pure JavaScript. Lightweight, extensible, and WebMCP-native, it runs on any stack and can connect to any SSE backend. Developers can start with a floating launcher in the corner, a copilot docked beside an app, or a full-height assistant that owns the page, changing the launcher configuration without changing the agent or app. Persona is designed for support, docs, sales, onboarding, internal tools, and custom agent experiences where the chat UI becomes another way to operate the application. Through WebMCP, developers can expose page actions, search, carts, bookings, forms, and other tools directly in the browser through a document.modelContext; Persona discovers those tools, asks the user before calling them, and streams the result back into the conversation.

About

WebMCP is an open source JavaScript library that allows any website to integrate with the Model Context Protocol, enabling users to connect to and interact with webpages through an LLM or AI agent. Developers can add WebMCP to a site with a simple script, which initializes a small widget that handles the connection between the webpage and an MCP client. Once connected, websites can expose MCP features including tools, prompts, resources, and sampling. Tools let an LLM perform actions on the website through registered functions with defined inputs and outputs. Prompts provide reusable templates for common LLM interactions and can accept dynamic arguments. Resources expose webpage data and content that clients can read and use as context, including page content, individual elements, files, or other structured information. WebMCP also supports sampling, allowing the server to request LLM completions through the connected client while maintaining human oversight.
