Today, AWS announces the developer preview of the AWS API model context protocol (MCP) server, a new tool that enables foundation models (FMs) to interact with any AWS API through natural language by creating and executing syntactically correct and valid CLI commands.

With the AWS API MCP Server, customers using popular MCP clients can streamline tasks like troubleshooting workloads, managing application deployments, and exploring AWS services and capabilities more easily, by issuing natural language requests that the host FM can translate into API calls.

The AWS API MCP Server allows MCP clients to discover supported AWS APIs and make calls to them through the host FM, enabling actions such as inspecting, creating, and modifying AWS resources. The server provides secure access control through AWS Identity and Access Management (IAM) credentials and pre-configured API permissions, ensuring that FMs can only access or perform authorized actions on permitted AWS APIs.

The AWS API MCP Server is released as an open source project and available now. Visit the AWS Labs GitHub repository to download, deploy, and start experimenting with natural language interaction with AWS APIs today.

Today, AWS announces the preview release of AWS Knowledge Model Context Protocol (MCP) Server, a new tool that surfaces authoritative AWS knowledge in an LLM-compatible format, including documentation, blog posts, What’s New announcements, and Well-Architected best practices.

AWS Knowledge MCP Server enables clients and foundation models (FMs) that support MCP to ground their responses in trusted AWS context, guidance, and best practices, providing the guidance needed for accurate reasoning and consistent execution, while reducing manual context management. Customers can now focus on business problems instead of searching for information manually.

The server is publicly accessible at no cost and does not require an AWS account. Usage is subject to rate limits. Give your developers and agents access to the most up-to-date AWS information today by configuring your MCP clients to use the AWS Knowledge MCP Server endpoint, and follow the Getting Started guide for setup instructions.

Amazon EBS now provides visibility into the EBS volume initialization status for volumes created from EBS snapshots. You can use this status to determine when your volume becomes fully initialized when restoring from a snapshot and is fully ready to support latency-sensitive applications.

EBS volumes that are created from EBS snapshots undergo volume initialization, in which the storage blocks from the snapshot must be downloaded from Amazon S3 and written to the volume before you can access them. The volume initialization rate fluctuates throughout the initialization process, which could make completion times unpredictable. During initialization you may notice increased I/O latency and reduced performance. Our new volume initialization status feature allows you to validate when all blocks have been downloaded and written to the volume, enabling fully provisioned performance on your volume. Using this status, you can time your application launches to align with volume initialization completion. Monitor initialization progress in real-time and launch your applications only when volumes are fully ready, ensuring optimal performance from the start. When creating volumes with Provisioned Rate for Volume Initialization, you will also be able to see the estimated completion time for your volume initialization.

Volume initialization status is accessible by default for all EBS volumes. It is available in all AWS Regions, including the AWS GovCloud (US) Regions and AWS China Regions. You can start using this feature today through the AWS Management Console, AWS Command Line Interface (CLI), or AWS SDKs. To learn more about the new volume initialization status and how to access it, please visit the EBS initialize volume documentation.

Amazon CloudWatch now helps you observe generative AI applications and workloads, including agents deployed and operated with Amazon Bedrock AgentCore (Preview), providing insights into AI performance, health, and accuracy. You get an out-of-the-box view into latency, usage, and errors of your AI workloads to detect issues faster in components like model invocations and agents. You can also find issues faster using end-to-end prompt tracing of components like knowledge bases, tools and models. This feature is compatible with popular generative AI orchestration frameworks such as Strands Agents, LangChain, and LangGraph, offering flexibility with your choice of framework.

With this new feature, Amazon CloudWatch analyzes telemetry data across components of a generative AI application, helping quickly identify the source of errors. For example, you can pinpoint the source of inaccurate responses — whether from gaps in your VectorDB or incomplete RAG system retrials — using end-to-end prompt tracing, curated metrics and logs. This connected view of component interactions helps developers optimize workloads faster to deliver high levels of availability, accuracy, reliability, and quality. Developers can keep AI agents running smoothly by monitoring and assessing the fleet of agents in one place. The agent-curated view is available in the “AgentCore” tab in the CloudWatch console for genAI observability. Generative AI observability is integrated with other CloudWatch capabilities such as Application Signals, Alarms, Dashboards, Sensitive Data Protection, and Logs Insights, helping you seamlessly extend existing observability tools to monitor generative AI workloads.

This feature is available in Preview in 4 regions: US East (N.Virginia), US West (Oregon), Europe (Frankfurt), and Asia Pacific (Sydney). To learn more, visit documentation. CloudWatch pricing applies for collected and stored telemetry data.

Amazon Bedrock AgentCore enables developers to deploy and operate AI agents with the scale, reliability, and security critical to real-world applications. It provides purpose-built infrastructure to scale agents securely, powerful tools to enhance agent capabilities, and essential controls to ensure trustworthy operations. AgentCore services are modular and composable, allowing them to be used together or independently. They work with any model—in or outside of Amazon Bedrock—and any open-source agent framework, eliminating the trade-off between open-source flexibility and enterprise-grade security.

Amazon Bedrock AgentCore include services and tools that address the barriers to moving agents from proof of concept to production. AgentCore Runtime provides complete session isolation with low latency and supports long-running workloads up to 8 hours. AgentCore Memory enables agents to maintain both short-term and long-term memory across interactions with zero infrastructure management. AgentCore Gateway simplifies tool integration and discoverability, enabling developers to convert existing APIs and services into Model Context Protocol (MCP)-compatible tools with minimal code. AgentCore Browser Tool provides a secure, cloud-based browser runtime so agents can interact with web-based services and perform complex web tasks. AgentCore Code Interpreter offers a secure, sandbox environment so agents can execute code across multiple languages. AgentCore Observability provides real-time visibility into end-to-end agent execution and key operational metrics through dashboards powered by Amazon CloudWatch and is OpenTelemetry compatible. AgentCore Identity allows users to invoke agents by integrating with existing identity providers such as Amazon Cognito, Microsoft Entra ID, and Okta and enables agents to then securely access AWS resources and third-party tools and services.

The preview of Amazon Bedrock AgentCore is currently available in US East (N. Virginia), US West (Oregon), Asia Pacific (Sydney), and Europe (Frankfurt). Learn more about Amazon Bedrock AgentCore and it’s services in the News Blog and explore in-depth implementation details in the AgentCore documentation.
