You don't need to know any of this to use the SDK, but if you're wondering what each dependency is for:
* `mcp-types`: every protocol type (requests, results, content blocks) as its own package, versioned in lockstep with the SDK. Every `from mcp_types import ...` in these docs is this package.
* `mcp-types`: every protocol type (requests, results, content blocks) as its own package, versioned in lockstep with the SDK. Code that depends on `mcp` imports it through the `mcp.types` alias (every `from mcp.types import ...` in these docs); import `mcp_types` directly only in a project that installs `mcp-types` without the SDK.
* [`anyio`](https://anyio.readthedocs.io/): the async runtime. The whole SDK is written against anyio, so it runs on either `asyncio` or `trio`.
* [`pydantic`](https://docs.pydantic.dev/): what every `mcp_types` model is built on, plus all schema generation and validation.

* [`httpx2`](https://pypi.org/project/httpx2/): the HTTP client behind the Streamable HTTP and SSE *client* transports, with server-sent events support built in.
* [`starlette`](https://www.starlette.io/), [`uvicorn`](https://www.uvicorn.org/), [`sse-starlette`](https://pypi.org/project/sse-starlette/), and [`python-multipart`](https://pypi.org/project/python-multipart/): the HTTP *server* transports.
