Sell agent skills and MCP servers on AI tool marketplaces
Turn expertise or a working integration into something AI agents can install. A skill is a SKILL.md file of instructions, prompts and examples that teaches an agent like Claude Code or Cursor a task (for example a legal-clause review or an SEO audit); an MCP server is code that connects agents to a tool or data source. Package it, pass the marketplace's security review, then price it as a one-time sale, a subscription or, for hosted servers, per call. Free listings and a free tier help you collect installs and reviews before charging. Most MCP directories (Smithery, mcp.so, Glama) are free listing boards with no payments, so pick a marketplace with built-in checkout.
