We are excited to announce the launch of mcp-vertex-search-snippets, released on August 29, 2025. This project introduces a lightweight Model Context Protocol (MCP) server that brings the powerful discovery capabilities of Google Cloud’s Vertex AI Search directly to your MCP-compatible AI clients.

Core Capabilities

At the heart of mcp-vertex-search-snippets is the search tool. This tool allows your AI models to query a configured Vertex AI Search application and retrieve the most relevant information from your indexed documents.

To ensure the highest possible accuracy and grounding, the server employs a smart retrieval hierarchy:

  1. Extractive Segments: It first prioritizes precise, high-quality sections of a document that directly answer the query.
  2. Snippets: If no extractive segments are found, it falls back to relevant snippets.
  3. Document Metadata: As a final resort, it provides the document title and a link.

The server is built for flexibility, supporting both standard stdio transport for local integration and a streamable HTTP mode for remote hosting. Configuration is straightforward, supporting YAML files, environment variables, and command-line flags to define your Project ID, location, and App ID.

Why It Matters

For developers and organizations utilizing Large Language Models (LLMs), grounding is the key to reducing hallucinations and increasing trust. By integrating Vertex AI Search via the Model Context Protocol, you can give your AI agents real-time access to your organization’s proprietary knowledge base without complex custom glue code.

The use of extractive segments is particularly significant; instead of passing large chunks of text that might dilute the model’s attention, mcp-vertex-search-snippets delivers the exact pieces of information needed to answer a user’s question, leading to more concise and accurate AI responses.

Getting Started

Ready to enhance your AI’s knowledge? You can get started with mcp-vertex-search-snippets in two ways:

  • Pre-compiled Binaries: Download the binary for your operating system (macOS, Linux, or Windows) from the GitHub Releases page.
  • From Source: If you have Go installed, you can install it directly using: 
    go install github.com/UnitVectorY-Labs/mcp-vertex-search-snippets@latest

Once installed, simply configure your vertex.yaml with your Google Cloud project details and connect it to your favorite MCP client.
