[Server] Schema not removed after injecting SessionInterface #168
Description
Describe the bug
I noticed that $_session can be injected in tools, but it requires entering a session in the inspector. However, after entering it, it doesn't get overridden, but rather becomes SessionInterface.
To Reproduce
<?php
namespace app\mcp;
use Mcp\Capability\Attribute\McpTool;
use Mcp\Server\Session\SessionInterface;
class example
{
#[McpTool(name: 'example_tool')]
public function exampleTool(SessionInterface $_session): array
{
return [
'status' => 'ok',
'session_id' => $_session->getId()->toRfc4122(),
];
}
}Expected behavior
Support SessionInterface injection and remove related schema
