Is @barnburner121/plugin-hub-mcp safe?
The largest Claude Code plugin marketplace. 500 plugins, 600+ developer tools in one MCP server. Security, testing, DevOps, CI/CD, databases, frontend, backend, API design, ML/AI, mobile, cloud, serverless, authentication, monitoring, and more.
This server can change things — files, a browser, a database, or paid online services. Limit what it can reach.
Why: controls a web browser.

How to use it safely
- ✓ Use a separate browser profile without your logged-in accounts.
- ✓ Content it fetches from the internet can carry prompt-injection instructions.
- ✓ Pin the version (below) so an update can't change what it does without you noticing.
Code patterns worth reviewing
Automated pattern matches in the published package. Some are expected for this kind of server, and some may be false positives — they are pointers for review, not confirmed vulnerabilities.
External content fed into the prompt without isolation
The agent pulls in outside content (web pages, emails, retrieved documents) and adds it to its prompt, with no visible marking of that content as untrusted data.
