# `Snodo.Client.Session`
[🔗](https://github.com/joshrotenberg/snodo/blob/v0.4.1/lib/snodo/client/session.ex#L1)

The initialize-era session a `Snodo.Client` negotiated.

`Snodo.Client.connect/2` and `Snodo.Client.direct/2` fill it in after a
successful `initialize` and `notifications/initialized` on a 2025-11-25 or
2025-06-18 connection. On a 2026-07-28 connection the client's `session` is
`nil`: that protocol has no handshake, and `Snodo.Client.discover/1` returns
the server's capabilities and instructions instead.

  * `version` - the negotiated protocol version, the same as the client's
    `protocol`.
  * `id` - the `Mcp-Session-Id` the server issued with the `initialize`
    response, or `nil`. Over HTTP the client sends it with every later
    request and in the `DELETE` that `Snodo.Client.close/1` issues.
  * `server_info`, `server_capabilities`, `instructions` - from the
    `initialize` result, as the server sent them.

# `t`

```elixir
@type t() :: %Snodo.Client.Session{
  id: String.t() | nil,
  instructions: String.t() | nil,
  server_capabilities: map(),
  server_info: map(),
  version: String.t()
}
```
