agent-mail

The script is a feature-rich bootstrapper that automates repo management, environment setup, and server startup for MCP Agent Mail. Principal security concerns center on the heavy reliance on remote installers via curl | bash, persistent environment modifications (PATH, RC files), and exposure of tokens to subprocesses. While the fragment itself does not show explicit malware, its behavior elevates supply-chain and runtime risks if remote components are compromised or if the environment is multi-tenant or untrusted. Recommendations include pinning remote installer sources or replacing with signed artifacts, implementing integrity checks (checksums or signatures), reducing or constraining persistent environment modifications, and ensuring token handling is minimized and auditable (prefer passing tokens via secure channels and with minimal exposure in process listings/logs). If feasible, use in-house vetted installers, or fetch verifiable artifacts instead of executing scripts directly via curl | bash.
