There is no shortage of places to list an agent, a skill or an MCP server. There is a shortage of places where listing one earns money. This is a comparison from public sources as of October 2026; every claim links to where it comes from, and numbers from vendor marketing are marked as such.
Vendor stores
OpenAI. The GPT Store launched in January 2024 with a revenue-sharing promise that was still to come at launch. By October 2024 Wired reported that the program had reached only a small, invite-only group of US builders. The successor, apps in ChatGPT (Apps SDK), opened to submissions with an app directory, but selling digital goods or subscriptions inside ChatGPT was not allowed as of early 2026, and the revenue model was still undefined in autumn 2026. Custom GPTs retire on 11 December 2026.
Anthropic. Claude Code has an official plugin marketplace (claude-plugins-official) and a community marketplace; both are free, and there is no paid shelf for skills. Distribution, not revenue.
AWS. The AWS Marketplace “AI Agents and Tools” category launched in July 2025 with more than 900 listings from established vendors. Buyers come through cloud contracts; it is not a place for an individual creator.
Independent marketplaces
| Marketplace | Model | What is public about creator money |
|---|---|---|
| Agent.ai | free network of agents, credit-based usage | 258k users in Jan 2025, later reports of ~2M; no creator payout program found |
| Poe | per-message pricing and subscription revenue for bot creators | the only large marketplace with active creator monetization (secondary source) |
| Apify Store | pay-per-event actors, 80% to the creator minus compute | Apify’s own page claims $500k+ paid out monthly (vendor claim) |
| MCPize | paid MCP servers, 85% to the developer | early; figures from secondary sources |
| n8n Creator Hub, n8nmarket, N8N Central | workflow templates | community users call n8nmarket “a ghost” |
One widely repeated figure: of more than 12,000 MCP servers, fewer than 5% have monetized (secondary source, treat as indicative).
What this means if you build packs
- A skill or plugin is a text file. It is easy to copy, so the file itself is not what sells. What sells is the thing that is hard to copy: evidence that it works, kept current.
- The buyers are concentrated in vendor stores that do not pay creators yet. Listing there is still worth it for distribution; expecting revenue from it is not.
- Independent marketplaces compete on liquidity. A new one without buyers cannot help you; an old one with buyers (Apify, Poe) takes 15–20% and gives you payment rails you would otherwise have to build.
This catalog takes a different position: it does not sell anything on behalf of creators. It lists packs with public facts and, where a pack has been through a verification run, a measured agreement score with a human expert. How verification works.
