The revenue tier breakdown by category is a useful framing — the gap between developer infrastructure ($$$$ for database query optimizers) and general utility tools is wider than most builders realize. One pattern I've noticed in the ecosystem is that MCP servers with persistent state across sessions tend to command higher pricing because they reduce context-rebuilding overhead. The Docker/Kubernetes config generator idea at $$ seems underpriced given how much debugging time misconfigured YAML costs teams in production.
