Provides automatic access to comprehensive MCP server development, tool design, and testing skills.
<!-- AUTO-GENERATED by export-plugins.py — DO NOT EDIT -->
Manages MCP servers by discovering, analyzing, and executing tools/prompts/resources via CLI scripts. Use for integrations, capability discovery, tool filtering, and context bloat resolution.
Converts MCP servers into on-demand skills to reduce context window usage by 10-30%. Classifies each tool by replacement strategy and generates the skill package.
