Wisco Labs: developer tools
Check PyPI and npm upgrades: known vulnerabilities, the safe version, and what each upgrade breaks.The vendor's description, from its MCP Registry listing.
Every public check ran and passed. Public audit: we connect as an AI client would, list the tools and check what they say. We do not run them. How we audit
- Does it work?
- YesConnected in 270 ms.
