Agent 37

Agent 37 is a platform designed for creators who build custom skills for Anthropic's Claude AI. It solves a practical problem: how to sell or share a Claude skill without requiring buyers to go through a complex local installation process. Instead of distributing source code, creators upload their skill to Agent 37, which hosts it and provides a unique, shareable URL. Anyone with the link can interact with the AI skill directly in their browser, with no need for a Claude account or technical setup. This turns a niche technical asset into an accessible product.

The service handles the entire technical and commercial backend. It includes a free trial system, allowing potential customers to experience the skill's value before committing to a subscription. Payments are processed through Stripe, and Agent 37 automatically handles payouts, with creators keeping 80% of the revenue. The platform is built specifically for the Claude Model Context Protocol (MCP), meaning it can host skills that utilize MCP servers for expanded capabilities like web search or data access.

Agent 37 is ideal for AI developers, coaches, and consultants who have built a useful Claude skill and want to generate income from it. A real-world example from the site is a creator who turned her startup coaching expertise into a skill and gained 43 paying subscribers. It removes the barrier of technical deployment, allowing creators to focus on improving their AI agent while Agent 37 manages hosting, payments, and distribution.
