The axios breach is a good opportunity to review your package manager settings
I recommend pnpm @pnpmjs
Default: postinstall scripts are blocked, protects against axios vector
Also try:
- minimumReleaseAge: 10080 (pkgs must be min 7 days old)
- trustPolicy
- blockExoticSubdeps

Yep all our repos use pnpm-workspace.yaml, it's the standard way of configuring many security features like allowBuilds, minimumReleaseAge, trustPolicy, etc

I've been thinking about this project for a while and finally found the time to materialise it! github.com/metcoder95/fuse-b…
A small library with utilities to apply resiliency patterns to (almost) all kinds of workloads!
Feedback is always welcome :)

Scaling AI agents isn’t just about speed — it’s about state (and security).
In this session, @matteocollina (Co-Founder & CTO at @Platformatic) shows how to build stateful #MCP servers using Node.js, Platformatic & Fastify — and secure them with @Auth0.

There has been considerable discussion on how to implement Authentication using OAuth in MCP, including a lot of criticism on using Dynamic Client Registration (DCR).
I've partnered with Auth0 to demonstrate how it's possible to implement this and provide a secure authentication flow for your MCP users in Node.js using @platformatic technology.

I have represented (with @metcoder95) the @nodejs team on the @github secure course, and it was awesome to see and share with many other excellent projects.
If you haven't already, I recommend that you apply your project
