Show HN: Webmcp-kit – type-safe toolkit for Chrome's new WebMCP API
xtrkil Sunday, February 15, 2026
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!
Summary
webmcp-kit is a comprehensive web development framework that provides a modern and efficient toolkit for building web applications. It includes a router, middleware, view engine, and other essential components to help developers create scalable and maintainable web projects.
