ContainerAdapter

Wraps Quiote’s DI Container as the PSR-11 container mcp/sdk uses (Mcp\Server\Builder::setContainer()) to resolve string/array tool handlers (Mcp\Capability\Registry\ReferenceHandler::getClassInstance()).

Quiote’s own Container::has() deliberately reflects only explicit registrations/aliases, not autowireable classes (see its docblock) — so ordinary callers can’t observe autowiring through a PSR-11 has() check. But MCP tool/resource/prompt handler classes are typically plain autowireable classes that are never explicitly bound. If has() returned false for those, ReferenceHandler falls back to new $class(), bypassing DI (and any constructor dependencies) entirely. This adapter reports any loadable class as present so get()’s autowiring path resolves it instead.

Synopsis

final class ContainerAdapter implements ContainerInterface

Implements	ContainerInterface
Source	Bridge/ContainerAdapter.php

Constructor

__construct()

public function __construct(Container $container): mixed

Parameter	Type	Description
$container	Container

Returns mixed

Methods

Method	Description
get(string $id): mixed	Resolves $id through the wrapped Quiote container, autowiring it when it has no explicit registration.
has(string $id): bool	Reports whether $id can be resolved.

get()

public function get(string $id): mixed

Resolves $id through the wrapped Quiote container, autowiring it when it has no explicit registration.

Parameter	Type	Description
$id	string

Returns mixed

has()

public function has(string $id): bool

Reports whether $id can be resolved.

True for anything the wrapped Quiote container has an explicit registration or alias for, and additionally for any loadable class name, so mcp/sdk routes autowireable handler classes through ContainerAdapter::get() instead of instantiating them itself.

Parameter	Type	Description
$id	string

Returns bool
