Portview MCP Server
See what's on your ports, then act on it. So can your AI agent. lsof -i is slow and cryptic. ss -tlnp is unreadable. netstat is deprecated. You just want to know what's on port 3000 and kill it.
People who need developer tools tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

Security posture
What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.
license MIT - declared in the repository
registry namespace io.github.Mapika is GitHub-verified and matches the repo owner
02 · What Portview can do
Prose above is summarized from the project's README and registry record - no invented capabilities.
Limitations (from the README)
- Linux: Other users' ports are listed, but naming the process needs sudo (it reads /proc/ /fd/). Rows you can't attribute show - for PID, user, process, and command rather than being hidden. - macOS: Other users' ports are not listed without sudo - sockets are enumerated per process via proc_pidfdinfo, so a process that can't be opened contributes nothing to enumerate. For the same reason doctor cannot detect TIME_W
