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.
| What | Cotal | nopua |
|---|---|---|
| Risk grade | BB · Some risk signals Based on public adoption and transparency signals as of Oct 24, 2026. Our opinion, not a code audit or security guarantee. | CC · Moderate risk signals Based on public adoption and transparency signals as of Oct 21, 2026.

| Type | AI agent skill | AI agent skill |
| Est. context load | ~50 tokens idle · ~450 tokens when active (on-demand skill) | ~113 tokens idle · ~450 tokens when active (on-demand skill) |
| GitHub stars | 370 | 1.4k |
| Weekly npm downloads | 20.3k | — |
| Local files | No local folder access noted | No local folder access noted |
| Command execution | No shell command runner noted | Runs shell or system commands |
| Network reach | Connects to outside service API | Connects to outside service API |
| Credentials | No API token required | No API token required |
| Package source | npm (@cotal-ai/core) | GitHub (wuji-labs/nopua) |
| Install command | npx -y @cotal-ai/core | Source repo only |
| Bottom line | Cotal is experimental software with low adoption, so use it only in controlled environments with trusted agents until the project matures and proves its security. | nopua is distributed via GitHub (wuji-labs/nopua); review its source code, dependencies, and requested permissions before use. |
