Make your AI better at system maintenance. IceShore is a configuration-management platform for teams whose systems have multiplied as AI sped up development. Alongside each system's architecture, it prompts your AI to organize what the system does for the business (its use cases) and serves the result back to it over MCP. Your AI can then explain a change's impact on business operations, on processing, and on external systems itself, instead of guessing from the code alone. The auto-generated architecture diagrams also let you check how well the AI understands each system. For example, ask your AI "If we stopped the medical-records database, who would be affected?" It reads the use cases behind the architecture and answers with the people and business processes that depend on that database. No account needed to try it: list_samples, get_content and get_guide work anonymously on the public sample workspaces. Sign in (free for a single person) to work with your own systems. Endpoint: https://mcp.iceshore.ai/mcp (Streamable HTTP). Auth: OAuth 2.1.
