Outils

Ce que ce MCP expose

Outil	Entrées	Quand appeler
Catalog browse	query?	Finding a vetted skill
Permission inspect	skill_name	Before install
Install	skill_name	After inspection
Migrate	local_path	Cleaning up accretion
Publish	skill_path, listing	Submitting new skills

Coût et limites

Coût d'exécution

Quota d'API: None
Tokens par appel: 0 at marketplace level; depends on each skill
Monétaire: Free
Astuce: Prefer marketplace installs over raw clones to cut audit overhead.

Sécurité

Permissions, secrets, portée

Stockage des identifiants : No credentials at marketplace level

Sortie de données : Marketplace itself doesn't egress; each listed skill declares its own egress

Audit ≠ zero risk. Still review each skill's declared egress and permissions before enabling for sensitive work.

Dépannage

Erreurs courantes et correctifs

Skill install fails signature check

Update marketplace clone; signing keys may have rotated

Vérifier : git -C ~/.claude/skills/marketplace pull

A marketplace skill behaves differently from raw upstream

Marketplace sometimes pins older versions for audit stability; check manifest for pinned commit

Alternatives

marketplace vs autres

Alternative	Quand l'utiliser	Compromis
agent-skills-cli-skill	You want a larger, less-curated catalog	Less audit, more options
awesome-llm-skill	You want community breadth	Quality varies widely
