AWS SSO Identity Store MCP Server
The AWS SSO Identity Store API, provided by Amazon Web Services as the foundational data layer for AWS IAM Identity Center (formerly AWS Single Sign-On), serves as a centralized and authoritative repository for managing digital identities within an enterprise's cloud ecosystem.
Quick Start Summary
The AWS SSO Identity Store MCP server is a Model Context Protocol bridge that connects AI assistants — including Claude Desktop, Cursor, Windsurf, and VS Code Copilot — to the AWS SSO Identity Store API through natural language. It exposes 10 API endpoints as callable tools, such as CreateGroup, CreateGroupMembership, CreateUser, 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-identitystore. This integration is sourced from the auto AWS SSO Identity Store OpenAPI specification (v2020-06-15) 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.
DescribeGroup tool to confirm the group's existence and retrieve its unique ID before generating a policy that correctly references it. Furthermore, workflows can be automated with commands like, "After deploying the new microservice, add all members of the 'BackendEngineering' group to the 'MicroserviceOperators' IAM Identity Center group," prompting the AI to use CreateGroupMembership to execute the change. It could also respond to queries such as, "List all users who are members of both the 'Contractors' and 'LondonOffice' groups," by sequentially utilizing GetGroupId, ListGroupMemberships, and DescribeUser to compile a report, assisting in compliance reviews or access auditing. This transforms the AI from a mere code composer into an active participant in identity lifecycle management.identitystore:* actions—and no more, adhering to the principle of least privilege. The MCP server endpoint should be secured via TLS and access should be restricted to authorized developer tooling networks. Developers must treat the credentials provided to the MCP server as highly sensitive, avoiding hardcoding them and instead using secure secret management solutions. Furthermore, all AI-agent-driven mutations (Create*, Delete*) should be considered high-risk operations and should ideally be preceded by a "dry run" or confirmation step in the developer's workflow to prevent accidental mass-modification of identity records. Logging all API calls made through the MCP server is essential for audit trails and security monitoring, ensuring that every automated change to the enterprise identity fabric is traceable.Similar APIs

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.
