Scored across 5 tools
Each tool targets a distinct resource and action: listing spaces, publishing/updating content, rolling back to a prior live version, searching documentation, and listing versions. The overlap between publish and rollback is clearly bounded by rollback's restriction to previously live versions, so an agent can select correctly.
The set mixes noun-style query names (my_spaces, versions), a verb_noun search name (search_docs), and bare verb action names (publish, rollback). The convention is readable but not a predictable verb_noun pattern throughout.
Five tools is well-scoped for a focused publishing platform: list spaces, publish/update, rollback, inspect versions, and search docs. Each tool has a clear role and none feels redundant or missing from the count.
The core lifecycle is covered: create/update via publish, revert via rollback, inspect versions, list spaces, and get help via docs. Minor gaps remain—there is no explicit delete/unpublish or metadata-editing tool—but agents can work around these for most publishing workflows.
Available Tools
5 toolsmy_spacesYour spacesARead-onlyInspect
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.
Inputs: no named parameters. Returns: handle, spaces
publishPublish a spaceAInspect
Publish a browser game, or any other page or project that runs in a browser, 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 and devices from the person. To update a space pass space (signed in) or claim (not signed in).
Inputs: sdk, spa, clip, game, +11 more. Returns: space, terms, reason, status, +9 more
rollbackRoll back a spaceADestructiveIdempotentInspect
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.
Inputs: space (required), version (required). Returns: status, pageUrl, version
search_docsSearch Velven's docsARead-onlyInspect
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.
Inputs: query (required), limit. Returns: query, results
versionsVersions of a spaceARead-onlyInspect
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.
Inputs: space (required). Returns: space, versions
