Agent Skills (skills.sh format), plugins and the MCP server for Velven, the community marketplace and host for spaces built with AI.
onboard/ teaches a coding agent to publish a space on Velven: velven publish makes a private preview, --prod
puts it live after Velven's safety check, and it works before the creator has an account (an unlisted page with a
claim token to keep it). It fills velven.json from the project, links an already deployed site as the side path,
claims a space that is already on Velven, and adds sign-in, leaderboards, saves, achievements and rooms through the
Velven SDK.plugins/velven/ is the same skill with Velven's MCP server, as a plugin for Claude Code and Codex.Skill only, for any agent that reads skills.sh skills:
Claude Code, the plugin (the skill and the MCP server):
Codex: add this repository as a plugin marketplace (.agents/plugins/marketplace.json) and install velven.
Gemini CLI, the MCP server: gemini extensions install https://github.com/velvenai/skills.
https://mcp.velven.ai/mcp, Streamable HTTP. Tools: publish (one HTML page or a few files, 3 MB in all: a preview,
or live with prod: true), my_spaces, versions, rollback and search_docs. Without signing in, publish makes an
unlisted page and answers its claim token; the account tools ask you to sign in to Velven (OAuth). Any client that takes
a remote MCP server adds it by that address, for example:
server.json is its entry in the MCP Registry (io.github.velvenai/velven).
