Registry of MCP-derived skills with progressive disclosure. Use when asked about "github", "assistant-ui", "MCP tools", or any converted MCP server. Provides 90%+ context savings compared to native MCP loading.From its SKILL.md

MCP Skills Registry

Central directory for all MCP-derived skills. Each sub-skill wraps an MCP server with progressive disclosure.

⚠️ These Are Skill Wrappers, NOT Native MCP Tools

You CANNOT call mcp__shadcn__*, mcp__github__*, etc. directly - those don't exist. These skills wrap MCP servers via a central executor.py.

Usage

Step 1: Read the skill's SKILL.md (from project root):

cat .claude/skills/mcp-skills/<skill-name>/SKILL.md

# Example: shadcn skill
cat .claude/skills/mcp-skills/shadcn/SKILL.md

Step 2: Use the central executor.py (from project root):

# List available skills
python .claude/skills/mcp-skills/executor.py --skills

# List tools in a skill
python .claude/skills/mcp-skills/executor.py --skill github --list

# Get tool schema
python .claude/skills/mcp-skills/executor.py --skill github --describe create_issue

# Call a tool
python .claude/skills/mcp-skills/executor.py --skill github --call '{"tool": "create_issue", "arguments": {...}}'

Context Efficiency

Scenario	Native MCP (all servers)	This Registry	Savings
Idle	40-100k tokens	~150 tokens	99%+
Using 1 skill	40-100k tokens	~5k tokens	90%+
After execution	40-100k tokens	~150 tokens	99%+

How It Works

Registry loads first - This file (~150 tokens)
User requests a tool - e.g., "create a GitHub PR"
Sub-skill loads - Only the relevant skill's SKILL.md (~4k tokens)
Executor runs - External process, 0 context tokens
Result returned - Context drops back to registry only

Adding New Skills

Use the mcp-to-skill-converter skill:

cd .claude/skills/mcp-to-skill-converter
python mcp_to_skill.py --name <server-name>
# Outputs to .claude/skills/mcp-skills/<server-name>/

Skill Structure

Each sub-skill contains:

.claude/skills/mcp-skills/<skill-name>/
├── SKILL.md           # Tool documentation
├── executor.py        # Async MCP client (legacy, use central executor)
├── mcp-config.json    # Server config
└── package.json       # Dependencies

This registry enables progressive disclosure of MCP servers as Claude Skills.
