A marketplace of skills, MCP servers, and model providers for AI coding agents — Claude Code, Codex, and friends.
🛒 Browse & install → · ⬇️ Download desktop → · 🧩 Contribute →
Discover and one-click install the building blocks that extend your AI coding agent, all from one place:
| 🎯 Skills | Reusable SKILL.md capabilities, fetched on install |
| 🧩 MCP servers | npx stdio or remote http/sse servers, wired into your tool's config |
| 🔌 Providers | Model relays with a pre-filled connection — you just add your key |
A desktop client manages what's installed, runs a local relay that forwards and fails over between providers, and tracks your usage.

The catalog is an open, PR-driven registry — anyone can add or update a package.
Every package is a single JSON manifest in registry:
mcp/<slug>.json skill/<slug>.json provider/<slug>.json
- Open a PR adding your manifest (or use the store's Publish form, which opens the PR for you).
- CI validates the schema and checks that install URLs resolve.
- A maintainer reviews; on merge it goes live in the store.
Popular packages are also proposed automatically by a crawler that opens PRs — reviewed the same way.
