Agents are using a web built for humans. Pages and controls were designed to be seen and operated by people, not discovered and invoked reliably by software. WebMCP begins to solve this by giving websites a native way to expose capabilities to agents.

We built Signett to make it easy for web developers to prepare their websites for the agentic era. It is a small open-source TypeScript library that brings WebMCP together with identity, policy, idempotency, observability, verification, and deterministic testing. Developers can build production-ready tools for agents in less time while keeping application logic and state in their application.
