Best AI Agent Marketplaces for Codex CLI

Agensi serves as a specialized marketplace for AI agent skills that have been rigorously curated. Each skill undergoes thorough security scanning, is compatible with over 20 agents—including Claude Code, Codex CLI, Cursor, Gemini CLI, and Copilot—and is developed by a responsible creator. Skills are available for one-time purchase only, allowing buyers to retain ownership indefinitely without the hassle of subscriptions or license keys. Utilizing the open SKILL.md standard, a single purchase ensures functionality across all compatible agents. Every submission is subjected to an extensive 8-point automated security check, addressing concerns like prompt injection, data exfiltration, hazardous commands, secret detection, and obfuscated code. Creators benefit from receiving 80% of the proceeds from each sale, with quick payouts via Stripe, while downloads are fingerprinted for the protection of the buyer's IP. In addition, Agensi provides a MCP subscription option priced at $9 per month or $90 annually, granting AI agents live access to the entire skill catalog. This subscription allows agents to connect seamlessly to Agensi through MCP, enabling them to search for and load the appropriate skills in real-time during conversations. With this service, no downloads or file management are required, and new skills become available instantly upon their release. This model not only streamlines the user experience but also fosters continuous innovation in AI capabilities.
