## Definition

An **SDK** (Software Development Kit) is a package that gives developers a convenient way to interface with an API — as in `pip install stripe`.

&lt;Section title=&quot;What an SDK does here&quot;&gt;An **SDK** (Software Development Kit) is a package that gives developers a convenient way to interface with an API. Alex Rattray's example: instead of hand-writing HTTP requests, you type `pip install stripe` and get a ready-made client library. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@536]&lt;/Section&gt;&lt;Section title=&quot;The MCP analogy&quot;&gt;Rattray frames **MCP** by analogy to SDKs: SDKs give developers an easy way to interface with an API — so what gives **LLMs** an easy way to do the same? MCP is his obvious answer, though as it rolls out it &quot;isn't working so great.&quot; [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@536]&lt;/Section&gt;&lt;Section title=&quot;Where SDKs show up next: code execution&quot;&gt;The emerging alternative to exposing hundreds of MCP tools is **code execution**: the model gets one tool to run TypeScript against the API's SDK and one to search its docs. Finding a customer among paginated transactions becomes nested loops running server-side — about ten lines of context, roughly 1,000 tokens up front, no round trip to the model per step. This only works because the SDK is statically typed: a type checker catches hallucinated method calls in real time and returns relevant docs inline. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@2142] [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@2398]&lt;/Section&gt;&lt;KeyPoints&gt; - An SDK is the developer-facing wrapper around an API (`pip install stripe`). [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@536] - Rattray uses SDKs to explain why MCP exists: it is, in effect, an SDK for LLMs. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@536] - In the code-execution pattern, agents run code against typed SDKs instead of clicking through many tools. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@2142] - Static typing in the SDK catches hallucinated calls and guards against errors. [^913c216d-5ccb-51d9-8f42-8feb7c017d9d@2398] &lt;/KeyPoints&gt;
