AWS has published “Agent Plugins for AWS,” an open-source set of packaged workflows that let AI coding agents translate prompts like “deploy to AWS” into a guided deployment sequence, starting with a deploy-on-aws plugin that works in Claude Code and Cursor.
AWS said a task that would have taken ‘hours of reading documentation, comparing services, and writing infrastructure code’ took ‘less than 10 minutes’ using the deploy-on-aws plugin.
What AWS released and how it works
The initial deploy-on-aws plugin runs a defined five-step workflow: analyze the codebase, recommend AWS services with rationale, estimate costs, generate infrastructure-as-code in CDK or CloudFormation, then deploy only after user confirmation.
The GitHub README says the plugin can connect to three Model Context Protocol (MCP) servers, a somewhat standard way for coding agents to call external tools and data sources. Those servers cover AWS documentation and best practices, real-time pricing, and infrastructure-as-code guidance.
For context, MCP is an open protocol for connecting LLM applications to external data sources and tools. Infrastructure-as-code refers to templates that provision and configure cloud resources programmatically rather than by manual setup.
AWS’ launch post also lists best practices: review generated code against security, cost and resilience constraints, apply least-privilege AWS credentials and run security scanning tools on generated infrastructure code.
Least privilege means granting only the minimum permissions required for a task, reducing the blast radius if credentials are misused.
Why the launch lines up with Cursor’s marketplace
Cursor shipped plugin support shortly after and positioned plugins as bundles of “skills” plus components like MCP servers, hooks and rules that extend its agent with external tools and knowledge.
Cursor said its initial set is curated and includes AWS, with discovery and installation through the Cursor Marketplace and in-editor commands.
AWS’ own instructions mirror that distribution path, pointing Cursor users to the Marketplace and listing Claude Code as another supported entry point.
What AWS says enterprises should do when using the plugin
AWS’ launch post includes explicit cautions for teams using agent plugins to create and deploy infrastructure. AWS tells users to review any generated code before deployment against constraints such as security, cost and resilience.
It also recommends using plugins as accelerators rather than replacements for developer judgment. AWS further advises applying least-privilege AWS credentials for plugin-driven operations and running security scanning tools on generated infrastructure code.
What the plugin’s workflow includes
The open-source repository describes deploy-on-aws as a guided workflow that can assess a project, recommend AWS services, estimate costs and generate infrastructure-as-code before deployment.
The repository documentation also describes the plugin as bundling AWS MCP servers, including an AWS Pricing server intended to support cost estimation as part of the flow.
