Use Cases & Benefits
- Implements an early WebMCP proposal enabling websites to share tools and resources with client-side large language models via a local websocket server.
- Eliminates the need to share API keys by allowing any LLM model to connect securely through scoped tokens and local communication.
- Use for integrating client-side LLMs with website-specific tools and prompts to enhance user or agent interactions without server-side API exposure.
- Use for developers experimenting with decentralized LLM tool sharing and token-based authentication between MCP clients and web pages.
- Use for deploying a local MCP websocket server in Docker to manage multiple simultaneous LLM connections and tool executions across domains.

You likely want the official W3C repo + spec: https://github.com/webmachinelearning/webmcp
This was an early WebMCP proposal / implementation. I was just a guy with a dream.
The idea of WebMCP has since evolved and is being worked on by much more capable folks that develop the web.
This implementation is not compliant with the W3C spec.
All this being said, please do feel free to try it out, as it demonstrates the value of WebMCP.
A proposal and code for websites to support client side LLMs
WebMCP allows websites to share tools, resources, prompts, etc. to LLMs. In other words, WebMCP allows a website to be an MCP server. No sharing API Keys. Use any model you want.
It comes in the form of a widget that a website owner can put on their site and expose tools to give client-side LLMs what they need to provide a great UX for the user or agent.
The look, feel, how it's used, and security are all absolutely open for contribution / constructive criticism. MCP Clients directly building WebMCP functionality seems like an ideal outcome.
An end-user can connect to any number of websites at a time - and tools are "scoped" (by name) based on the domain to simplify organization.
