Visa CLI
Visa CLI, created by Visa Crypto Labs, is an innovative command-line interface that empowers AI agents and automated systems to perform secure card payments straight from the terminal, marking the advent of a new concept known as "command line commerce." This tool enables developers to seamlessly incorporate payment functionalities within their coding environments, eliminating the need for conventional API keys or pre-funded accounts, which in turn simplifies the setup process and reduces the security vulnerabilities tied to managing credentials. Users, along with AI agents, engage through text commands rather than graphical interfaces, making the system inherently more suitable for machine-driven operations and automation. With Visa CLI, programmatic payments are supported, enabling agents to efficiently pay for services like APIs, datasets, or digital resources in real-time workflows. Furthermore, it employs advanced security measures such as tokenization and certificate-based access to ensure that transactions are secure while also streamlining the implementation process. This makes Visa CLI a powerful tool in the evolving landscape of digital payments, catering to the needs of developers and automated systems alike.

Preloop
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.
