Compare two AI tools side by side
Put any two skills or MCP servers next to each other: risk grade, what each can access, how popular it is, and how to install it.

| Type | AI agent skill | AI agent skill |
| Est. context load | ~68 tokens idle · ~450 tokens when active (on-demand skill) | ~54 tokens idle · ~450 tokens when active (on-demand skill) |
| GitHub stars | 46 | 36.5k |
| Weekly npm downloads | 216 | — |
| Local files | No local folder access noted | Reads local files |
| Command execution | Runs shell or system commands | No shell command runner noted |
| Network reach | Connects to outside service API | Connects to outside service API |
| Credentials | Requires API key or token | No API token required |
| Package source | npm (@dollhousemcp/mcp-server) | GitHub (virgiliojr94/book-to-skill) |
| Install command | npx -y @dollhousemcp/mcp-server | Source repo only |
| Bottom line | mcp-server connects to external service APIs; restrict its folder reach, network access, and credentials before installing. | book-to-skill (agent skill) requires careful permission scoping — data residency: PDF content uploaded to external services may be retained server-side; verify data deletion policies before using proprietary or sensitive materials. |
