Tools
| Tool | Description | Behaviour |
|---|---|---|
| my_spaces | List the spaces of the signed-in Velven account: slug, title, status, whether Velven hosts it, and its page. Needs sign-in; called without it, the app asks the person to sign in to Velven. | Read-only |
| publish | Publish a browser game, world, tool or wonder on Velven's hosting, from one HTML page or a small set of files (3 MB in all). Signed in: a private preview by default, or with prod: true the next live version, live on its Velven page within seconds. Not signed in: an unlisted page, live the same way, returned with a claim token that keeps it. A new space needs title, type and devices from the person. To update a space pass space (signed in) or claim (not signed in). | Changes data |
| rollback | Make an earlier version of a hosted space live again. Only a version that was live before (rollback: true in versions) can be picked; it goes live at once. Needs sign-in. | Destructive |
| search_docs | Search Velven's documentation: publishing and hosting, velven.json, the CLI, the SDK (sign-in, leaderboards, saves, achievements, rooms), claiming a page, the agent API and limits. Returns the best matching sections with links. | Read-only |
| versions | List a hosted space's versions, newest first: number, status (uploading, preview, publishing, live, refused, unjudged, replaced), size, and whether rollback can pick it. Refused versions carry the reason. Needs sign-in. | Read-only |
