Improve your agent’s tool-calling accuracy with SFT and DPO on Amazon SageMaker AI

Improve your agent’s tool-calling accuracy with SFT and DPO on Amazon SageMaker AI

AI agents can autonomously handle complex, multi-step tasks, but their effectiveness depends on calling the right tools to retrieve information or take action. When an agent picks the wrong tool, formats parameters incorrectly, or breaks a workflow chain, task completion times grow, error rates rise, support costs increase, and user experiences degrade. As more organizations […]

How Baz improved its AI Agent Code Review accuracy using Amazon Bedrock AgentCore

How Baz improved its AI Agent Code Review accuracy using Amazon Bedrock AgentCore

Code review was always manual and ineffective because of the inherent disconnect between code and product. Developers could review whether code compiled and worked, but not whether it fulfilled all functional and design requirements. In the past, QA teams spent hours manually clicking through preview environments to ensure features behaved as expected, and even more

Building a secure auth code flow setup using AgentCore Gateway with MCP clients

Building a secure auth code flow setup using AgentCore Gateway with MCP clients

In modern development workflows, developers increasingly rely on agentic coding assistants such as Kiro Integrated Development Environment (IDE) to interact with remote tools and services. However, organizations require robust authentication mechanisms to provide secure, identity-verified access between these agentic coding assistants and enterprise Model Context Protocol (MCP) servers. Amazon Bedrock AgentCore is a fully managed

Reference your own AWS Secrets Manager secrets in Amazon Bedrock AgentCore Identity

AI agents are only as powerful as the tools they can access. Whether retrieving customer data from a CRM, posting updates to Slack, or querying a GitHub repository, agents need to call external APIs, and that means securely passing credentials at runtime. Getting that right, without hardcoding secrets in code or exposing them in agent

Transforming rare cancer research with Amazon Quick: Integrating biomedical databases for breakthrough discoveries

Transforming rare cancer research with Amazon Quick: Integrating biomedical databases for breakthrough discoveries

Rare cancer research generates heterogeneous data across genomic sequencing pipelines, clinical trial registries, biomarker repositories, and peer-reviewed literature. Integrating these sources for a single investigation typically requires custom ETL pipelines, manual schema reconciliation, and iterative querying across disconnected systems—a process that can take weeks before any analysis begins. Amazon Quick Research addresses this integration challenge

Extending MCP support for Amazon Bedrock AgentCore Gateway

Extending MCP support for Amazon Bedrock AgentCore Gateway

While deploying Model Context Protocol (MCP) servers in production, enterprises need fine-grained access control across servers, observability into which teams use which tools, security guarantees against data exfiltration, and centralized credential management, all at scale. Amazon Bedrock AgentCore Gateway sits between MCP servers and the clients that consume them, centralizing credential management, observability, and secure
