Skill vs MCP server
| Skill | MCP Server | |
|---|---|---|
| How it works | Adds context to Claude's prompt | Gives Claude callable tools |
| Install | npx skills add kknd0/clawcard | claude mcp add clawcard -- npx clawcard-mcp |
| Execution | Claude runs CLI via Bash | Claude calls MCP tools directly |
| Best for | Guided workflows with explanations | Direct programmatic access |
You can use both together — the skill provides workflow guidance while the MCP server provides direct tool access.
