Skill Jack MCP dynamically integrates Agent Skills into LLMs, providing on-demand access to specialized instructions and resources through MCP tools and resources.
Activate Skills - Use the
skilltool to load complete SKILL.md content by name, providing your LLM with step-by-step instructions and guidance for specific tasksAccess Skill Resources - Use the
skill-resourcetool to read specific files (scripts, snippets, templates, references, assets), list available files, or load entire directories within a skillDynamic Discovery - Automatically detects and updates available skills from configured directories when SKILL.md files change, sending
tools/listChangednotifications to clientsResource URIs - Access skills via
skill://URIs for manual selection in MCP clients, supporting single files, directories, or the main SKILL.md contentReal-time Updates - Subscribe to resources for notifications when skill files change, enabling live updates via
notifications/resources/updatedProgressive Disclosure - Follows Agent Skills pattern—lightweight metadata (name, description, location) loads first, then full instructions and files as needed
Multiple Directories - Configure one or multiple skills directories with automatic scanning, deduplication, and searching across all sources
Security Features - Includes path traversal prevention, configurable file size limits, and directory depth limits, while treating skill content as trusted
