Agent Marketplace
Definition
A platform where pre-built agents, skills, or agent components can be discovered, evaluated, and deployed — analogous to app stores for mobile or package registries for developers. Agent marketplaces may offer: complete agents (ready to run), agent templates (customizable starting points), skills/plugins (capabilities that can be added to existing agents), or MCP servers (tool integrations). The marketplace model assumes agents become composable — you build your system by assembling proven components rather than building everything from scratch.
Builder Context
Agent marketplaces are still nascent but watch this space. When evaluating marketplace agents: (1) check what data they access and where it goes (security); (2) verify they work with your model provider (compatibility); (3) test with your actual use cases, not demos (reliability); (4) understand the update/maintenance model (sustainability). For agent builders: the marketplace opportunity is less about building general-purpose agents and more about solving specific vertical problems deeply.
