BillingClient MCP Server
The BillingClient API, provided by Microsoft, serves as a programmatic gateway for querying and managing financial transaction records specifically for Azure subscriptions acquired through the Web-Direct purchasing channel.
Quick Start Summary
The BillingClient MCP server is a Model Context Protocol bridge that connects AI assistants — including Claude Desktop, Cursor, Windsurf, and VS Code Copilot — to the BillingClient API through natural language. It exposes 4 API endpoints as callable tools, such as Operations_List, Invoices_List, Invoices_GetLatest, 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/azure-com-billing. This integration is sourced from the auto BillingClient OpenAPI specification (v2017-02-27-preview) and has a quality score of 28/99 (fair documentation coverage).

📖 Detailed MCP Integration Guide
A technical breakdown of capabilities, agent workflows, and security/configuration best practices.
Microsoft.Billing/read permission at the specific subscription scope, avoiding broader Contributor or Owner roles. Best practices include using managed identities where possible, storing credentials in a secure vault like Azure Key Vault, and ensuring all API calls are made over HTTPS. Configuration of the MCP server should allow for the secure passing of subscription context, and developers should ensure that logging and monitoring are enabled to audit all data access performed by the AI agent, maintaining compliance and oversight.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.
