Azure ACR MCP Server Integration Guide
Quick Start Architecture Summary
The Azure ACR MCP server is a Model Context Protocol integration that connects AI assistants (Claude Desktop, Cursor IDE, VS Code, Zed) to the Azure ACR API through natural language directives. It exposes 9 API operations as callable MCP tools, including Registries_CheckNameAvailability, Registries_List, Registries_ListByResourceGroup, and more. No authentication is required — operates out of the box immediately. Sourced from the auto Azure ACR OpenAPI specification (v2016-06-27-preview) with an overall quality score of 34/99.
Technical Overview & Protocol Integration
The ContainerRegistryManagementClient API is a comprehensive RESTful service provided by Microsoft as part of Azure Resource Manager, designed to manage the lifecycle of Azure Container Registry (ACR) instances.
By converting the OpenAPI 3.0 specification for Azure ACR into native Model Context Protocol (MCP) tool definitions, developers and AI agents gain programmatic access to endpoints over stdio or HTTP transports. Every endpoint is translated into a discrete tool payload complete with input argument validation, parameter descriptions, and return type definitions.
This setup enables LLM agents to execute multi-step workflows, search records, mutate state, and analyze responses safely within local desktop client sessions like Claude Desktop and Cursor IDE.

7. Error Resolution & Troubleshooting Guide
HTTP status codes and JSON-RPC protocol error resolution matrix.
400 Bad RequestRoot Cause: Malformed request payload parameters or missing required JSON Schema fields.
Resolution Action: Verify request schema in Section 5 tool specifications before calling operation.
401 UnauthorizedRoot Cause: Missing or invalid API key credentials in MCP environment config.
Resolution Action: Define required key in client config under env object.
403 ForbiddenRoot Cause: Insufficient scope permissions or unauthorized resource access.
Resolution Action: Check key permissions in developer control panel.
404 Not FoundRoot Cause: Resource URL path or requested target ID does not exist.
Resolution Action: Inspect path parameters and resource ID values.
429 Rate Limit ExceededRoot Cause: Upstream API rate limit quota exceeded.
Resolution Action: Implement exponential backoff retry in tool execution loop.
500 Internal Server ErrorRoot Cause: Upstream service runtime fault or stdio process crash.
Resolution Action: Inspect STDIO stderr output stream for diagnostic trace.

Box Platform API MCP
The Box Platform API, provided by Box (box.com), is a robust and comprehensive RESTful service that enables deep integration with the Box cloud content management ecosystem. It serves as the programmatic backbone for enterprises and developers seeking to build custom applications and workflows that interact with content stored securely in Box. Its core capabilities extend far beyond basic file operations, encompassing a full spectrum of content lifecycle management. Developers can programmatically create, upload, download, search, and manage files and folders, but the API's true power lies in its enterprise-grade features. These include advanced collaboration management through invitations and permissions, granular user and group administration within an enterprise directory, and sophisticated security and compliance controls. Specific endpoint groups for managing collaboration whitelists and exempt targets allow for precise governance over external sharing policies, ensuring that content is only shared with approved domains. Furthermore, the API facilitates complex legal and compliance use cases, such as placing items on legal hold or applying retention policies, making it an indispensable tool for regulated industries and large organizations.
Asana MCP
This API serves as the programmatic backbone for the Asana work management platform, provided by Asana, Inc. It enables developers to interact programmatically with one of the world's leading enterprise collaboration and productivity suites. The core capabilities of this interface center around the CRUD (Create, Read, Update, Delete) operations for fundamental Asana objects. Specifically, the provided endpoints grant control over project attachments—allowing for the uploading, retrieval, and management of files associated with tasks and projects—and custom fields, which are pivotal for creating structured, data-rich workflows. These custom fields allow organizations to define unique data types (like dropdown menus, text fields, or dates) to standardize information capture across projects, moving beyond basic task lists to true operational tracking. Typical use cases span from enterprise project management offices (PMOs) needing to programmatically generate status reports and audit attachments, to development teams automating the creation of bug-tracking projects with predefined custom fields for severity and status, to operational leaders building dashboards that aggregate and analyze custom field data for resource allocation insights.
