AI agents can talk to ClownVPN through a small set of registered functions. WebMCP exposes them — same idea as the JSON-RPC MCP but running in the browser, callable from any AI client that supports it.
WebMCP is a small open-source widget (~29 KB, no dependencies) that turns a static webpage into an MCP-capable endpoint. An AI agent with MCP support — Claude Desktop, ChatGPT custom GPTs, local agents — can call registered functions on the page just like a regular MCP server.
Widget source: github.com/jasonjmcghee/WebMCP. Loaded on this page. Open the page and your MCP-aware agent will see the four tools below.
Four functions. Read-only — no state changes on our side.
