AWS Knowledge Base Retrieval MCP Server

An MCP server implementation for retrieving information from the AWS Knowledge Base using the Bedrock Agent Runtime.

Features

  • RAG (Retrieval-Augmented Generation): Retrieve context from the AWS Knowledge Base based on a query and a Knowledge Base ID.
  • Supports multiple results retrieval: Option to retrieve a customizable number of results.

Tools

  • retrieve_from_aws_kb
    • Perform retrieval operations using the AWS Knowledge Base.
    • Inputs:
      • query (string): The search query for retrieval.
      • knowledgeBaseId (string): The ID of the AWS Knowledge Base.
      • n (number, optional): Number of results to retrieve (default: 3).
    • Response format:
      • The response now returns two separate content items:
        • A text item containing the raw context from the knowledge base.
        • A JSON item containing the structured RAG sources with metadata (id, fileName, snippet, and score).
      • This separation allows for more flexible processing of the results.

Building

docker build -t mcp/aws-kb-retrieval -f src/aws-kb-retrieval-server/Dockerfile .
