Description

Kastra serves as the crucial authorization framework for AI systems, determining the permissions of agents, models, and tools prior to their execution. Positioned along the execution path of all interactions such as prompts, tool calls, shell commands, database operations, and API requests, it evaluates each action based on deterministic, attribute-driven policies, rendering decisions to allow, deny, redact, or escalate in less than a millisecond. In contrast to monitoring solutions that only track AI actions post-execution, Kastra proactively prevents unauthorized activities before they can impact any tool, API, database, or production environment. Its comprehensive control plane integrates a policy engine, edge decision-making capabilities, various integrations, and a tamper-proof evidence vault that securely signs each decision for auditing and replay purposes. Furthermore, with Kastra Edge, local enforcement is extended to developer environments, safeguarding coding agents such as Claude Code, Cursor, and Codex CLI from harmful commands, unauthorized data extraction, unsafe file modifications, and improper tool usage. This proactive approach to authorization not only enhances security but also ensures compliance and accountability in AI-driven processes.

Description

StackRails serves as a platform designed for software architecture and AI coding governance specifically tailored for engineering teams. It creates a dynamic knowledge graph that encompasses repositories, services, APIs, events, and cloud infrastructure, enabling coding agents to access architecture and policy insights via the Model Context Protocol (MCP). This platform is compatible with tools like Claude Code, GitHub Copilot, Cursor, and OpenAI Codex, ensuring that generated code adheres to rules set by the organization on developers’ local machines and during pull-request processes. Engineering teams can leverage its capabilities to trace cross-repository dependencies, evaluate the impact of changes, keep architecture documentation up to date, oversee engineering policies, and conduct AI-driven architectural assessments. StackRails offers flexibility in deployment; it can be utilized as a hosted service in the EU, within customer-managed cloud settings on platforms such as AWS, Microsoft Azure, or Google Cloud, and it also supports on-premises installations for added security and control. This versatility ensures that organizations can adopt StackRails in a manner that best suits their operational needs and compliance requirements.
