AWS Well-Architected Tool MCP Server
The AWS Well-Architected Tool API provides programmatic access to the Well-Architected Tool, a service designed to help cloud architects review and improve their workloads against the AWS Well-Architected Framework's six pillars: Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability.
Quick Start Summary
The AWS Well-Architected Tool MCP server is a Model Context Protocol bridge that connects AI assistants — including Claude Desktop, Cursor, Windsurf, and VS Code Copilot — to the AWS Well-Architected Tool API through natural language. It exposes 10 API endpoints as callable tools, such as AssociateLenses, ListLensShares, CreateLensShare, 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-wellarchitected. This integration is sourced from the auto AWS Well-Architected Tool OpenAPI specification (v2020-03-31) 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.
wellarchitected:CreateWorkload or wellarchitected:GetLensShare. Sensitive operations, especially sharing lenses and workloads, must be tightly controlled. Best practices include using IAM policies that restrict access to specific workload IDs or lens aliases where possible, enabling AWS CloudTrail to log all API calls made by the server for auditability, and ensuring the MCP server itself is deployed in a secure context where its credentials (like an instance profile or environment variables) are not exposed. Developers should also be aware that sharing a lens or workload grants the recipient access to read its details, so shares should be managed with the same care as access to sensitive data.Similar APIs

Bearer TokenDigitalOcean API
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.
