Skybridge v2 ships new MCP protocol with Evals testing framework

By PulseAugur Editorial · [1 sources] ·

Skybridge has released version 2, introducing a new MCP protocol that has undergone significant changes, including becoming stateless and removing session IDs. This update necessitated a rebuild of the server architecture, shifting from a single McpServer instance to a factory pattern where a new server is instantiated for each request. A key new feature is Evals, a testing framework designed to allow developers to define and execute tests involving LLMs to ensure their applications function correctly before deployment. AI

IMPACT Enhances developer tooling for LLM-integrated applications by providing a framework for testing and validation.

RANK_REASON This is a software update for a specific tool (Skybridge) and its associated protocol (MCP), including a new feature (Evals), rather than a frontier model release or significant industry event.
