Documentation Overview
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 <a,b,…> | 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.
Env vars
| Var | Default | What it controls |
|---|---|---|
GITHUB_TOKEN | - | optional, read-only; raises GitHub's rate limit for full multi-file skill loads (60 → 5000 req/hr) |
SK_INLINE_BUDGET | 6000 | char cap on the in-context SKILL.md portion (the full skill is always on disk) |
SK_SYNTH_N | 5 | how many top skills synthesize_skills merges (2-8) |
SK_SYNTH_PER_SKILL | 12 | max rules kept per source skill |
SK_SYNTH_BUDGET | 4000 | char cap on the merged digest |
DO_NOT_TRACK | - | set 1 to disable the anonymous demand signal |
Troubleshooting
The agent doesn't see the tools. Some clients surface MCP tools lazily - tell the agent to search its tools for "skillselion" first (e.g. ToolSearch), then call it. The setup hook automates this nudge.
load_skill returns only the SKILL.md, no bundled files. You hit GitHub's unauthenticated 60 req/hr limit - set a read-only GITHUB_TOKEN in the server's env.
"No skill on Skillselion clearly matches..." The relevance floor working as intended - nothing topical matched, so it refuses to waste your context. Try a more specific query.
Setup couldn't auto-register. Run the printed claude mcp add ... line yourself.
