Taking this question at face value, because you asked: Stainless generates MCP servers for REST APIs (a ~simple[0] translation of an OpenAPI to a suite of MCP tools).

We actually generate MCP for free (we charge for SDKs), so we're technically not selling, but I don't begrudge GP's comment/sentiment.

[0]https://www.stainless.com/blog/what-we-learned-converting-co... describes some ways in which this is less simple than you think. The "Handling large APIs dynamically" section near the bottom covers the most salient challenge related to converting large APIs to MCP tools, but there's more work to do.

It's clearly a plot by Big MCP to sell us more MCP. /s
