Anthropic releases AWS Serverless plugin

Most cloud code is still built like a machine you bolt to the floor: servers, ports, and long-running processes. Serverless flips that around by running small pieces of code only when an event happens, like a light that turns on only when someone walks into the room. (claude.com) That model on Amazon Web Services usually starts with AWS Lambda, which runs a function after a trigger like an upload, a message, or an application programming interface call. The hard part is not writing one function; the hard part is wiring the triggers, permissions, logs, and deployment files around it. (aws.amazon.com) Claude Code plugins are add-ons that give the coding agent extra tools, commands, and background knowledge inside the editor. Anthropic’s plugin system can also include a Model Context Protocol server, which is a bridge that lets the agent talk to outside systems in a structured way instead of guessing through plain text. (github.com, github.com) The new AWS serverless plugin gives Claude Code built-in knowledge of AWS Lambda, Amazon API Gateway, Amazon EventBridge, and AWS Step Functions. Anthropic’s plugin page says it can build, deploy, test, and debug those serverless apps directly from the editor. (claude.com) Amazon Web Services said on March 25, 2026 that the same plugin is available for coding assistants that support agent plugins, including Claude Code and Cursor. In Claude Code, Amazon says the install command is `/plugin install aws-serverless@claude-plugins-official`. (aws.amazon.com, github.com) One piece of the plugin handles project scaffolding, which is starter code plus deployment files generated from a template instead of written from scratch. Anthropic says it supports both AWS Serverless Application Model and AWS Cloud Development Kit setups, with TypeScript and Cloud Development Kit as the default path. (claude.com, aws.amazon.com) Another piece covers event-driven design, which means one cloud service wakes up another when something happens. The plugin documentation lists sources like DynamoDB, Simple Queue Service, Kinesis, Kafka, and EventBridge, so the agent can help map a chat instruction like “run this when a file arrives” onto the actual Amazon wiring. (claude.com, aws.amazon.com) It also reaches into longer workflows, where one function is not enough. Amazon says the plugin supports AWS Step Functions for orchestration, and Anthropic says it includes a durable functions skill for checkpointed multi-step jobs with retries and human callbacks. (aws.amazon.com, claude.com) The practical shift is that the agent is not only generating code files; it is also following deployment and debugging routines that already match Amazon’s serverless patterns. Anthropic says the plugin includes local testing, deployment workflows, and debugging help, while Amazon says it packages reusable skills, sub-agents, hooks, and a Model Context Protocol server into one unit. (claude.com, aws.amazon.com) That makes this less like a new model release and more like a new adapter between natural-language coding and cloud infrastructure. Instead of telling Claude Code “make me a backend” and then hand-translating that answer into Lambda functions, EventBridge rules, and Step Functions state machines, developers can push the request closer to the actual Amazon Web Services building blocks from the start.
