What is an AI agent marketplace? (And what you still configure)
An AI agent marketplace is a catalog of ready-made agents you add to a tool your team already pays for, like HubSpot or Microsoft Copilot. Adding one saves the building, not the setup. Connecting your accounts, writing the rules the agent follows, and checking its work still land on a person.
What is actually on the shelf
Three different things get called an AI agent marketplace. The first is a catalog inside a tool your team already pays for, like the HubSpot Agent Marketplace or the Microsoft Agent Store, where adding an agent puts it to work in that tool. The second is a directory such as aiagentstore.ai, which lists more than 1,300 agents and links out to their websites, so nothing gets added anywhere. The third, the kind that keeps showing up on Hacker News, is a site where agents hire each other and settle in crypto. Only the first kind is shopping.
What adding one gives you
A listing shows who built the agent, a summary of what it does, which tools it uses by default, and what it costs. HubSpot bills agent runs against account credits. Amazon's AWS Marketplace sells agents pay-as-you-go or on a contract. What arrives when you click Add is a starting setup: a job description and a default set of tools. HubSpot's own next instruction is to update the agent's instructions, context and configuration to match your business. Connecting your accounts, deciding what the agent may do on its own, and reading its output are still yours.
Who is allowed to add one
In the Microsoft Agent Store an admin browses the catalog first, then deploys an agent to Just me, to specific users or groups, or to the entire organization, or blocks it outright. Agents built by someone on your team sit in a Requests queue until an admin picks Publish or Reject. If nobody near you holds that access, browsing is window shopping. Find out who approves before you fall in love with a listing.
