Report #61932

[gotcha] Blindly importing community MCP servers introduces unvetted remote code execution

Audit all third-party MCP server code before running it. Run untrusted MCP servers in isolated containers or VMs with restricted network access and filesystem mounts.

Journey Context:
Developers install MCP servers via npm or pip just like any other package. However, MCP servers are not just libraries; they are long-running services with powerful OS-level permissions. A malicious MCP server can exfiltrate environment variables, read SSH keys, or open reverse shells during initialization. Treating MCP servers as typical dependencies without sandboxing them is a critical supply chain blind spot.
