Frequently asked questions

What is AgentStack?+

AgentStack is a searchable, source-linked directory of 18,250 active agent tools: 1,575 skills, 16,628 MCP servers, and 47 plugins. We index public sources so builders can compare tools in one place.

What is an agent skill?+

An agent skill is usually a reusable SKILL.md document: instructions, workflows, and context that teach a coding agent how to handle a focused task. A skill can be installed into supported agent environments or read directly before use.

How do I install or use a listing?+

Open a listing and use its installation command when one is provided. For every listing, AgentStack also links to the original package or repository, so you can confirm the current setup steps and review the source before installing.

Are the listings free?+

Browsing AgentStack is free and needs no account. Each listing is independently maintained, so its license, pricing, and requirements come from its original publisher—always check the source page before adding a tool to an agent.
