description: 'HumanMirror has no separate test host, test mode or magic test values: every call — free or paid — hits production at https://humanmirror.fr. What it publishes instead is a free-first design: trial credits, per-day free quotas, a dry_run flag on the MCP tools, free quote/verify endpoints, and a hosted Playground that spends 23 of a free 100-credit Nexus key on three real verified calls.'
