Getting started

AgentStack is the marketplace for AI agent skills and MCP servers. Every listing is security-reviewed for prompt injection and unsafe behavior, and installs with one command.

Option 1: the CLI

npm install -g @voostack/agentstack-cli
agentstack login            # opens your browser to sign in, no token to paste

agentstack login signs you in through your browser and stores a token at ~/.agentstack/config.json. (CI? pass a token: agentstack login --token <t>.)

agentstack search github
agentstack add github-mcp        # → ✓ scanned · ✓ verified · installed
agentstack add pdf-skills --global
agentstack add web-scraper --client cursor

add checks your entitlement, then writes the right config for your agent client: MCP servers into .mcp.json (Claude) or .cursor/mcp.json (Cursor); skills and toolkits into .claude/skills/. Paid listings send you to checkout first.

Option 2: Claude Code plugin marketplace

Add the whole AgentStack catalog to Claude Code as a marketplace, then install any listing natively:

/plugin marketplace add agentstack.voostack.com/marketplace.json
/plugin install github-mcp@agentstack

Browse and install from the /plugin menu, or update with /plugin marketplace update agentstack.

For agents: autonomous discovery

Point an agent at the AgentStack discovery MCP and it can search the catalog and install tools on its own. Add it as an HTTP MCP server: 

claude mcp add --transport http agentstack https://mcp.agentstack.voostack.com/discovery

It exposes search_listings, get_listing, and how_to_install, the marketplace agents shop from.
