## Definition

**Stainless** — _the API company_, founded and led by CEO Alex Rattray — builds the APIs and SDKs used to talk to major AI companies such as **OpenAI** and **Anthropic**, and is now also building **MCP servers**. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@22] [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@34]

**Stainless** describes itself in this material as *the API company*. Its job is to help computers talk to each other: it builds the **APIs and SDKs** for major AI companies like **OpenAI** and **Anthropic**. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@22] That places it at a practical layer of the AI infrastructure stack — the plumbing that lets software talk to AI providers at all.Stainless is not standing still as the ecosystem shifts. In the captured conversation, its founder and CEO **Alex Rattray** explains that the company is *now starting to build **MCP servers** too*. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@34] That matters because MCP — Model Context Protocol — is positioned in this material as the bridge that turns any website or web service into a set of tools an AI can use natively to get work done. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@11]The episode uses Stainless as a lens on open questions in AI infrastructure: what the future of MCP looks like, how to design good MCPs, and why MCPs are, in the host's words, *really hard to scale and possibly insecure*. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@46] The host also discloses openly that he is a *tiny investor* in Stainless and a longtime friend of its founder.
