Muse Marketplace

Muse Marketplace

The open marketplace & registry for shareable Muse assets.

Muse users will soon be able to share Muse Avatars with each other — an avatar sharing pop-up, animated previews of avatar "modes" like *Working*, the works. But sharing needs somewhere to live: an open registry where anyone can publish an avatar, persona, voice, or bundle, where every file carries a checksum, and where "safe" means *actually checked*, not just claimed.

That is this repo. We are building the Muse Avatar marketplace — starting now, in the open.

npx @reneturcios/muse-marketplace list

npx @reneturcios/muse-marketplace search tree npx @reneturcios/muse-marketplace show jolly npx @reneturcios/muse-marketplace install jolly npx @reneturcios/muse-marketplace doctor

Or browse it as a site: open site/index.html (or the GitHub Pages deploy) — a dark, searchable grid with an animated mode switcher on every avatar.

What's inside

• `registry/` — The registry itself. Every listing is a folder registry/ s/ / with a listing.json + its asset files. Kinds: avatar (primary), persona, voice, bundle. registry/index.json is generated from the listings (muse-marketplace index), never hand-edited; CI fails on drift.
• Launch catalog (9 listings, all original, all installable) — 6 avatars: Jolly (the friendly green companion), Tree (a forest spirit), Straw Hat Explorer, Neon Founder, Cozy Scholar, Pixel Sprite — each with an original animated SVG per mode (idle / working / thinking / celebrating, plus extras like making, dance, milestone, error). 2 personas: Sharp Operator, Warm Companion. 1 bundle: Starter Pack (everything).
• CLI + MCP in one bin — muse-marketplace (alias mmkt) for humans; the same binary is an MCP server (muse-marketplace mcp) exposing marketplace_search, marketplace_list, marketplace_show, marketplace_validate, marketplace_install.
• `site/` — A zero-build static marketplace: search, filter by kind + tag, click a card for the animated mode switcher and a copyable install command.
• `docs/` — SPEC (the listing schema), PUBLISHING (submit via PR), VETTING (the safety model), MODES, ARCHITECTURE, ROADMAP.

Quickstart

npm install

npm run build npm test

node dist/cli.js list node dist/cli.js install jolly --dest ./muse-assets # copies files, verifies sha256 before AND after, writes install-receipt.json node dist/cli.js init my-avatar --kind avatar # scaffold a listing of your own node dist/cli.js validate my-avatar node dist/cli.js index # rebuild registry/index.json node dist/cli.js doctor # registry health

Publish a listing

1. muse-marketplace init --kind avatar
2. Replace the placeholder SVGs / persona.md with your real assets.
3. Run muse-marketplace validate until clean, then muse-marketplace index.
4. Open a PR. Full walkthrough: docs/PUBLISHING.md.

The vetting / safety model (short version)

Nothing gets to call itself safe here without receipts — the same rule we run across the fleet: *anything listed as safe must be validated with real checks.*

• No executables, ever. Only allowlisted media types (SVG/PNG/JPEG/GIF/WebP, markdown, plain text, JSON, audio). Validation rejects executable extensions outright.
• Checksums on everything. Every file in every listing records its sha256 + byte size. validate recomputes them; install verifies before *and* after copying and refuses tampered listings.
• Path safety. Absolute paths and .. traversal entries are rejected; installs stay inside the destination you name.
• Vetted is earned. safety.vetted flips to true only after the VETTING.md checklist is run by a reviewer — not by the author checking their own box.
• Personas are plain markdown you can read in full before using — the file *is* the payload, nothing hidden.

MCP usage

{ "mcpServers": { "muse-marketplace": { "command": "npx", "args": ["-y", "@reneturcios/muse-marketplace", "mcp"] } } }

Tools: marketplace_search · marketplace_list · marketplace_show · marketplace_validate · marketplace_install (install is confined to a caller-provided destination under the current working directory).

Roadmap

Ratings & reviews, signed listings, voice previews in the site player, a publish command that opens the PR for you, federation with other registries, and first-class wiring for Muse's native avatar sharing when it lands. Detail: docs/ROADMAP.md.
