Search the Versuz marketplace for Claude skills and CLAUDE.md files. Returns up to 15 matches per kind, ranked by prior + stars. Use when the user asks to find a skill for a task (e.g. 'PDF generation', 'database migration') or a CLAUDE.md for a project type.

List Claude skills from the marketplace. Filter by category, tier, or sort order. Use to browse what's available before installing.

List CLAUDE.md project-context files from the marketplace. Filter by category (nextjs, react, python-data, backend-api, mobile, devops, ml-training, generic).

Get full details for a specific skill or CLAUDE.md by slug — Elo, prior, license, GitHub link, bundle files, etc. Useful before deciding to install.

Install a skill (writes to .claude/skills/<slug>/SKILL.md) or a CLAUDE.md (writes to ./CLAUDE.md at project root). Only free items are installable via MCP — premium items return a buy URL the user must visit first.

Head-to-head comparison of two skills or CLAUDE.md files. Returns rank, bench score, prior, stars, tier, and a verdict (winner + delta). Use when the user asks to compare two items, pick a winner, or decide between options. Examples : 'compare pdf-generator vs anthropic-pdf', 'which is better : nextjs-supabase or nextjs-prisma'.

Submit a SKILL.md or CLAUDE.md from a public GitHub repo to the Versuz registry. Requires a GitHub Personal Access Token (PAT) configured via VERSUZ_GITHUB_TOKEN env var — the same token format as `npx versuz login`. Only the repo owner or a verified org member can submit. Free tier only via MCP ; premium submissions go through the web at versuz.dev/submit. Use when the user asks to publish their skill on Versuz, share a SKILL.md they wrote, or list their repo.

Versuz is an MCP (Model Context Protocol) server that connects Claude Code to the open Versuz marketplace. It lets you browse, inspect, and install skills and CLAUDE.md files as native tools directly from your conversation, without leaving the chat.

Install the server with claude mcp add versuz npx -y @versuz/mcp or add it manually to your project’s .mcp.json configuration. After restarting Claude Code, five Versuz tools appear in the tool list and can be invoked by name.
