Released on October 8, 2025, mcp-vertex-search-snippets v0.1.3 is a focused update centered on stability and reliability. This release marks a significant step forward in making the integration between the Model Context Protocol (MCP) and Google Cloud’s Vertex AI Search production-ready.

What’s new

The primary highlight of this release is the migration from the v1alpha to the stable v1 Vertex AI Search API. By moving away from the alpha endpoints, the server now leverages the official, stable version of Google’s search infrastructure.

Additionally, this version includes several under-the-hood improvements:

  • Updated Dependencies: The server now utilizes the latest versions of mcp-go and oauth2 for improved performance and security.
  • Language Upgrade: The project has been updated to Go 1.25.1, ensuring compatibility with the latest language features and optimizations.
  • Internal Refactoring: Domain selection logic for regional endpoints has been streamlined to improve code maintainability.

Why it matters

For users and developers, the move to the v1 API is the most critical change. Alpha APIs are subject to change and may lack the rigorous stability guarantees of production-grade endpoints. By transitioning to the stable API, mcp-vertex-search-snippets provides a more dependable foundation for AI clients to retrieve high-quality search snippets and extractive segments from indexed documents.

This update ensures that your MCP-powered AI tools are aligned with Google Cloud’s production standards, reducing the risk of breaking changes and increasing the overall reliability of your search-augmented workflows.
