Amazon Elastic Container Registry Public MCP Server
Amazon Elastic Container Registry Public (ECR Public) is a fully managed container image registry service provided by Amazon Web Services (AWS).
Quick Start Summary
The Amazon Elastic Container Registry Public MCP server is a Model Context Protocol bridge that connects AI assistants — including Claude Desktop, Cursor, Windsurf, and VS Code Copilot — to the Amazon Elastic Container Registry Public API through natural language. It exposes 10 API endpoints as callable tools, such as BatchCheckLayerAvailability, BatchDeleteImage, CompleteLayerUpload, and more. No authentication is required — setup takes approximately 30 seconds. The server uses STDIO transport and can be installed by running npx -y @mcp/amazonaws-com-ecr-public. This integration is sourced from the auto Amazon Elastic Container Registry Public OpenAPI specification (v2020-10-30) and has a quality score of 46/99 (fair documentation coverage).

📖 Detailed MCP Integration Guide
A technical breakdown of capabilities, agent workflows, and security/configuration best practices.
DescribeRepositories and DescribeImageTags endpoints and present the findings in a readable format. For maintenance, an instruction such as "Delete the old 'dev-environment' repository and all its images to clean up resources" would trigger the DeleteRepository action after the AI agent confirms the target. During development, a user might say, "Create a new repository named 'project-alpha' for our front-end component," leading the AI to invoke CreateRepository and return the repository URI for immediate use in a Dockerfile. Furthermore, the agent can perform security and compliance audits by querying DescribeImages to list images with outdated tags and report findings, or by using BatchCheckLayerAvailability to verify the integrity of specific image layers before a deployment.ecr-public:GetAuthorizationToken, ecr-public:DescribeRepositories, and narrowly scoped ecr-public:CreateRepository if required), and explicitly deny broader, unnecessary actions. Configuration should involve setting up a dedicated IAM user or role for the MCP server, ensuring credentials are securely stored (such as in environment variables or a secrets manager), and never hardcoding them. It is also essential to configure the MCP server connection itself with appropriate network security, such as operating within a private network or using secure tunneling, to protect the API traffic between the AI assistant and the ECR service.Similar APIs

The DigitalOcean API is a comprehensive, RESTful interface provided by DigitalOcean, a leading cloud infrastructure provider focused on simplifying cloud computing for developers, startups, and enterprises. It serves as the programmatic backbone for managing the entire DigitalOcean ecosystem, enabling users to provision, configure, and control cloud resources such as Droplets (virtual private servers), Kubernetes clusters, managed databases, networks, storage volumes, and application platforms. Core capabilities include full lifecycle management of these resources, from creation and scaling to monitoring and deletion, mirroring the functionality available in the DigitalOcean control panel. Its primary use cases range from automating infrastructure setup for CI/CD pipelines and enabling infrastructure-as-code practices to supporting dynamic application scaling and resource optimization for SaaS products, e-commerce sites, and development environments. The API is designed for both developers seeking to automate their cloud operations and businesses that require programmable, scalable cloud infrastructure without the complexity of larger hyperscale providers.

Access Analyzer MCP Setup
The AWS Identity and Access Management Access Analyzer API provides a powerful, policy-as-code service that automatically identifies resources accessible from outside your AWS account or organization. At its core, the service continuously evaluates resource-based policies—such as Amazon S3 bucket policies, AWS Identity and Access Management (IAM) roles, Amazon KMS key policies, and AWS Lambda function policies—using logic-based reasoning to determine which resources grant access to unknown external principals. Its primary use case is for security and compliance teams within enterprises to proactively detect unintended data exposure, enforce least privilege principles, and audit cross-account and cross-service access. The API endpoints allow programmatic control to create, configure, and query analyzers, manage archive rules for storing findings, and generate custom policy documents, making it a foundational tool for automating cloud security posture management at scale.
