I tested mcp-doctor pricing with 12 LLM-simulated personas. 4 said they would pay.

Earlier today I shipped /mcp-doctor - an open-source supply-chain trust scanner for MCP (Model Context Protocol) servers. CLI + GitHub Action + Trust Badge + free public API at. Pro tier is $19/mo on Gumroad. The honest question every solo founder skips: would anyone actually pay $19/mo for this? I have a separate tool for exactly this - personalab, an open-source persona-driven product evaluation harness. 12 LLM-simulated personas read the product, decide each day what they'd do, and tell you who would pay and who would walk away.
