Description
Preloop serves as an open-source control plane designed for AI agents that perform tangible actions. It integrates a multi-layered security approach featuring an MCP firewall for managing tool access, an AI model gateway that ensures cost-effectiveness, safety, and accountability, along with policy-as-code that incorporates human oversight, all while providing runtime session visibility and audit trails—all within a self-hosted environment. Given the rapid capabilities of AI agents to deploy code, modify infrastructure, manage financial transactions, access production data, and incur model costs almost instantaneously, Preloop empowers teams to regulate agent activities, monitor expenditures, and determine which actions necessitate human consent. It is compatible with a variety of tools such as OpenClaw, Hermes, Claude Code, Codex CLI, Cursor, Gemini CLI, Windsurf, Cline, OpenCode, and any agents that adhere to MCP standards. Additionally, access rules can evaluate not only the tool names but also arguments and context, utilizing CEL expressions to establish detailed conditions. Furthermore, teams have the flexibility to initiate with observability features and progressively introduce approval and denial protocols without the need for SDKs or extensive modifications to existing applications, thus streamlining the implementation process. This comprehensive approach ensures that organizations remain in control of their AI agents' functionalities and impacts.
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.
