**Show HN: Webmcp-kit – type-safe toolkit for Chrome's new WebMCP API**

WebMCP is a browser API that lets websites expose tools to AI agents. Chrome just shipped an early preview in Canary (behind a flag).I built webmcp-kit because the raw API is a bit tedious, you write JSON Schema by hand and get untyped inputs. This wraps it with Zod so you define schemas once and get TypeScript inference + validation.It also includes a dev panel to test tools without needing a real AI agent, works in any browser by falling back to a mock.Try it out and let me know.
