MCP-to-Skill Converter

Installation

The skill invokes .claude/tools/integrations/mcp-converter/batch_converter.py. Requirements:

• Python 3.10+: python.org or winget install Python.Python.3.12 (Windows), brew install python@3.12 (macOS).
• pip: Usually included with Python; verify with pip --version.
• Dependencies: From the repo root, install deps for the integration (e.g. PyYAML if required):
  bashCopy

  pip install pyyaml
  

  Run from project root; the script uses .claude/tools/integrations/mcp-converter/ (catalog: mcp-catalog.yaml).

Cheat Sheet & Best Practices

MCP design: Single responsibility per server; bounded toolsets; contracts first (strict I/O schemas); stateless by default; additive changes; security (identity, auth, audit). Prefer stdio for local, Streamable HTTP for remote; use a gateway for multi-tenant/centralized policy.

Conversion: Introspect server; estimate token usage of tool schemas; generate skill with progressive disclosure. Test converted skills before relying on them. Use catalog + batch_converter for rules-driven conversion.

Hacks: Focus on high-token or high-value servers first. Keep generated SKILL.md and wrappers in version control. Use mcp-catalog.yaml to mark keep_as_mcp or auto-convert thresholds.

Certifications & Training

MCP: MCP Best Practices, modelcontextprotocol.info. Skill data: Single responsibility, bounded tools, contracts first, stateless; stdio vs HTTP; gateway pattern; introspect → generate skill.

Hooks & Workflows

Suggested hooks: Post–MCP config change: optional batch_converter run to refresh skills. Use with evolution-orchestrator (add mcp-converter to secondary) when creating skills from MCP servers.

Workflows: Use with evolution-orchestrator. Flow: list servers → convert server or batch → test converted skill. See creators/skill-creator-workflow.yaml; mcp-converter feeds skill-creator input.

🚀 Usage

1. List Available MCP Servers

See which servers are configured in your .mcp.json:

python .claude/tools/mcp-converter/mcp_analyzer.py --list

2. Convert a Server

Convert a specific MCP server to a Skill:

python .claude/tools/mcp-converter/mcp_analyzer.py --server <server_name>

3. Batch Conversion (Catalog)

Convert multiple servers based on rules:

python .claude/tools/mcp-converter/batch_converter.py

ℹ️ How it Works

1. Introspect: Connects to the running MCP server.
2. Analyze: Estimates token usage of tool schemas.
3. Generate: Creates a SKILL.md wrapper that creates dynamic tool calls only when needed.

🔧 Dependencies

Requires mcp python package:

pip install mcp

Memory Protocol (MANDATORY)

Before starting: Read .claude/context/memory/learnings.md

After completing:

• New pattern -> .claude/context/memory/learnings.md
• Issue found -> .claude/context/memory/issues.md
• Decision made -> .claude/context/memory/decisions.md

ASSUME INTERRUPTION: If it's not in memory, it didn't happen.
