Anthropic
A private marketplace Claude Code already knows how to read.
Claude Code can point at an HTTPS marketplace endpoint, and that endpoint may return a different list per user. So we do not build an install experience — yours is already there, under /plugin.
Entitlement is a filtered array. When someone in Support fetches the catalog they get the four skills Support has; when someone in Data fetches the same URL they get eight skills and three MCP servers. Same endpoint, same command, different response.
Authentication goes through headersHelper — our CLI, printing an authorization header on demand. Claude Code gives that helper ten seconds and runs it from ~/.claude, and it strips environment variables containing TOKEN, SECRET, KEY or AUTH from sandboxed commands. So the token lives in the OS keychain, which is where it belongs anyway.
Every entry is served as an archive source pinned with a sha256, because a URL-served marketplace cannot use relative plugin paths. That has a useful side effect: you can verify that what landed on the machine is what we published.

Known limits
What Claude Code does not give us.
Stated up front, because you will find these out on day two anyway.
- Anthropic's own per-user provisioning needs a Team or Enterprise plan. On Bedrock, Vertex or Foundry you do not get it at all.
- Claude Code keeps no per-user marketplace state, so only a server can answer who currently has which version.
- We have not yet finished testing what happens to an already-installed plugin when it leaves the catalog, so we are not claiming instant revocation until we have.
FAQ
Claude Code, specifically.
Do we still need a Claude Team or Enterprise plan?
Not for Skill Belt. The marketplace endpoint works on any Claude Code install, which is the point — it is the path that works when the subscription-gated console does not apply to you.
What if Anthropic changes the marketplace protocol?
The CLI path keeps working. Claude Code's native marketplace is a convenience for us, not a dependency, and the same catalog serves three other clients through files on disk.
