The AWS Knowledge Base MCP Server is a comprehensive system allowing AI assistants to efficiently search and retrieve documentation and knowledge base data via AWS Bedrock, Pinecone, and Cloudflare Workers. It creates a scalable infrastructure with components like S3 for storage, Lambda for API functions, and a MPC server supporting streamable HTTP/ SSE transports. The server provides a tool called 'search_knowledge_base' that facilitates querying the stored knowledge data, enabling smarter and more accurate AI responses within various applications. Its architecture supports easy deployment, update, and integration of large documentation sets with high performance and security features.
