MCP server wrapping dig, ping, mtr, whois and TLS/HTTP checks for on-demand network diagnostics
netdiag-mcp is an MCP server distributed on pypi, maintained by AIKAWA Shigechika, tracked here since August 2026. It has shipped 5 releases (currently 0.6.0) and exposes 12 tools. Tools include asn_lookup, current_time, dns_lookup, dnssec_check, health_check, http_check, and 6 more. Its composite risk grade is A — an inferred review prompt computed from observed signals, not a verdict.
Reading the source raised 2 review prompts — exfiltration combo and toxic flow (lethal trifecta) — each a pattern worth a human look rather than a finding of fault.
Since the previous scan on 2026-09-11: 12 tools added and 10 tools removed.
