Released on August 2, 2026, v0.3.0 of mcp-vertex-search-snippets is a foundational update focused on alignment, stability, and future-proofing. While this release doesn’t introduce new tools, it significantly enhances the underlying architecture to ensure seamless integration with the evolving Model Context Protocol (MCP) ecosystem.

What’s new

The centerpiece of this release is the migration to the official Model Context Protocol Go SDK. By moving from a community-maintained library to the official github.com/modelcontextprotocol/go-sdk, the server is now directly aligned with the official MCP specifications.

Alongside the SDK migration, we’ve restored critical tool annotations. This means MCP clients now receive precise metadata—such as read-only and idempotency hints—allowing them to interact with the Vertex AI Search tool more intelligently.

We’ve also modernized the project’s core:

  • Runtime Update: The server now leverages Go v1.26.5, bringing the latest performance and security improvements.
  • Refined Authentication: We’ve streamlined the bearer token formatting for API requests, ensuring more reliable communication with Vertex AI Search.
  • CI/CD Overhaul: Updated GitHub Actions and security tooling to maintain a high standard of build quality and safety.

Why it matters

For users, these changes translate to a more stable and reliable experience. By adopting the official SDK, mcp-vertex-search-snippets is better positioned to support future MCP features as they are released. The restoration of tool metadata improves the “handshake” between the server and your MCP client, reducing ambiguity and improving the overall efficiency of search-driven workflows.

Upgrade and Installation

Upgrading to v0.3.0 is straightforward. You can download the latest pre-compiled binaries for macOS, Linux, and Windows directly from our GitHub Releases page. If you prefer installing from source, ensure you have Go v1.26.5 or later installed before running go install.
