# `ConduitMcp.Client.DiscoverResult`
[🔗](https://github.com/nyo16/conduit_mcp/blob/v0.11.0/lib/conduit_mcp/client/discover_result.ex#L1)

A modern (`2026-07-28`) server's answer to `server/discover`.

  * `supported_versions` - `supportedVersions`, in the server's order.
  * `capabilities` - the server's `ServerCapabilities`, string-keyed.
  * `instructions` - optional server instructions, or `nil`.
  * `ttl_ms` - how long the result may be cached. An absent, negative or
    non-integer `ttlMs` reads as `0`, as the caching page requires; any
    upper clamp is the cache's job.
  * `cache_scope` - `:public` or `:private`. Anything else (or absent)
    reads as `:private`, the scope that never shares across credentials.
  * `server_info` - `_meta["io.modelcontextprotocol/serverInfo"]` as a
    `ConduitMcp.Client.ServerInfo`, or `nil` when absent or malformed (it is
    a SHOULD, and display-only).
  * `meta` - the result's `_meta`, or `%{}`.
  * `raw` - the whole string-keyed wire map.

# `t`

```elixir
@type t() :: %ConduitMcp.Client.DiscoverResult{
  cache_scope: :public | :private,
  capabilities: map(),
  instructions: String.t() | nil,
  meta: map(),
  raw: map(),
  server_info: ConduitMcp.Client.ServerInfo.t() | nil,
  supported_versions: [String.t()],
  ttl_ms: non_neg_integer()
}
```

# `from_wire`

```elixir
@spec from_wire(term()) :: {:ok, t()} | {:error, ConduitMcp.Client.Error.t()}
```

Builds a `DiscoverResult` from a `server/discover` result map.

`supportedVersions` must be a list of strings and `capabilities` an
object, and `resultType` must be absent or `"complete"`; otherwise the
result is a `:protocol` error with reason `:invalid_discover_result`.

    iex> {:ok, result} =
    ...>   ConduitMcp.Client.DiscoverResult.from_wire(%{
    ...>     "resultType" => "complete",
    ...>     "supportedVersions" => ["2026-07-28"],
    ...>     "capabilities" => %{"tools" => %{}},
    ...>     "ttlMs" => 60_000,
    ...>     "cacheScope" => "public"
    ...>   })
    iex> {result.supported_versions, result.ttl_ms, result.cache_scope}
    {["2026-07-28"], 60000, :public}
