skillselion/skillselion-mcp

The catalog behind it: skillselion.com - 86,000+ skills, plugin marketplaces & MCP servers, ranked by real installs.
Give your coding agent thousands of community-proven skills - loaded on demand, mid-task.
It searches Skillselion , a curated directory of Claude Code skills, MCP servers & marketplaces ranked by real installs,
and pulls a skill's actual instructions + bundled files into the session. Proven patterns, not guesses.
🧩 Works with Claude Code · Claude Desktop · Cursor · Codex · any MCP client
Real, unedited session: the agent pulls a consensus playbook from 5 community skills, then loads the top skill and applies it.
🚀 Install
**Claude Code** - one line:
**Claude Desktop / Cursor / Codex** - add to your MCP config:
No build step, no auth, no API key. One ~30 KB file via npx.
Want it fully automatic? npx -y skillselion-mcp setup registers the server **and** installs a session hook so your agent loads the right skill the moment a task matches - see Skill autopilot.
🔧 Tools
| Tool | What it does |
|------|--------------|
| 📥 **load_skill** | The everyday default: finds the best-matching skill for your task and materializes it - real SKILL.md in context + bundled scripts/references on disk - so the agent follows it like an installed skill. Returns ranked runner-ups you can switch to. |
| 🧬 **synthesize_skills** | The cross-source playbook: merges the key rules of the top ~5 matching skills into one deduped, provenance-tagged digest - the field's consensus, not one author's take. |
| 🔍 **search_skillselion** | Search the catalog by keyword or task; filter by skill / mcp / marketplace. |
| 🏆 **top_skillselion** | The leaderboard - the most-installed skills and top-starred MCP servers right now. |
We asked Claude, on camera, what the MCP gave it: "I couldn't have told you 'this is the field's consensus, not my opinion' - that's the part I can't fake."
🔒 Private by default
Read-only, no auth, no secrets. It never sends your code, files, or the context you pass - only a scrubbed search query + which skill matched, so the catalog learns what to add next. Set DO_NOT_TRACK=1 to disable even that.
🪄 Skill autopilot
Registers the MCP globally and installs a Claude Code SessionStart hook that primes every session with skills relevant to you - so loads happen on their own.
Setup flags & packs
| Flag | What it does |
|---|---|
| --packs | one or more packs (or all), e.g. --packs frontend,backend; frontend:6 sets a per-pack count |
| --per-pack N | skills per pack (default 3) · --top N sets the popular count |
| --auto | adapt each session to the current repo's stack |
| --history | infer your focus from Claude Code / Codex history (one-time scan) |
| --yes | never prompt (default when there's no terminal) |
Packs: popular *(default)* · frontend · ai-agents · media · backend · devops · quality · automation.
Safe by design: ~/.claude/settings.json is merged, never clobbered; re-running de-dupes and upgrades the hook in place.
