Amazon Web Services has published an architectural guide for building a serverless Model Context Protocol server on Amazon ECS Fargate. The design aims to provide AI agents with metadata-driven access to enterprise data lakes without requiring custom per-dataset integration code.

Streamlining AI Agent Data Lake Access

Organizations building applications powered by artificial intelligence face a recurring challenge in giving large language model agents access to enterprise data lakes without duplicating integration logic across every agent and application.[1] Most teams begin by wiring agents directly to databases and APIs without a shared gateway, leading to custom code for each new dataset and fragmented access control.[1]

To address this for planning teams in Amazon's North America Sort Center network, developers built a serverless Model Context Protocol server on Amazon Elastic Container Service with AWS Fargate.[1] The server acts as an agent-agnostic gateway where exposing a new dataset requires only a JSON metadata file discovered automatically on pipeline sync.[1]

Architecture and Request Flow

The architecture separates concerns into client, MCP server, tools, and knowledge-base refresh layers.[1] Authenticated traffic enters a private subnet where the client layer runs on Amazon ECS Fargate, integrating with Amazon Cognito for JWT authentication and Amazon DynamoDB for session storage.[1]

In the MCP server layer, an AI agent powered by Amazon Bedrock orchestrates tools built with FastMCP while applying Amazon Bedrock Guardrails to every interaction.[1] The agent queries a metadata catalog, generates an optimized SQL query through Amazon Bedrock, validates and auto-corrects the SQL for Amazon Athena compatibility, and executes it.[1]

Verification and Testing

Performance figures and latency metrics cited by the developers are company-reported and have not been independently tested. The broader scope and real-world impact of the architecture outside of the described internal deployment have not been independently confirmed.
