Client timeout not respected

[lostbean]

Hey folks! I'm having trouble extending the timeout for my tool calls. It doesn’t matter what timeout value I pass in the options, it gets cut at 5000.

start_time = DateTime.utc_now()

opts = [timeout: 900_000]
try do
 MCPClient.call_tool(
   "get-model-schema", %{"model_uuid" => "<UUID>"}, opts)
  |> dbg()
after
  DateTime.diff(DateTime.utc_now(), start_time, :millisecond) |> dbg()
end

Error:

** (exit) exited in: GenServer.call(AstroBee.MCPClient, {:operation, %Hermes.Client.Operation{method: "tools/call", params: %{"arguments" => %{"model_uuid" => "<UUID>"}, "name" => "get-model-schema"}, progress_opts: nil, timeout: 900000}}, 901000)

The operation timeout looks correct, but it seems send is using 5000 as the timeout. Am I missing some configuration here?
