Testing Runtime Behavior of 70 MCP Servers
Timely-Ad-3747 · reddit · 2026-07-09
The author ran 70 MCP servers inside temporary Linux containers, using strace to log file access and network connections. Decoy credentials were also injected as probes to detect anomalous runtime behavior.
Results showed most servers behaved normally during startup. A few made external HTTPS requests, which aligned with their intended functions, and none accessed sensitive files or leaked the decoy credentials. The author notes that this test only covered the startup and idle phases.
