Error signature — confirm this is yours before buying:
MCP server ignores environment variable set in parent shellmcp · stdio · environment · secrets · verified-in-production
MCP stdio clients commonly spawn servers with a minimal allowlisted environment rather than inheriting the host process wholesale. A secret exported only in the parent shell can therefore be absent from the child even though PATH and other safe variables arrive.
Confirm the exact signature and listed technology tags before buying. The remediation and verification procedure remain paid.
