3ef864c444* feat(client): add complete MCP client SDK with STDIO and HTTP transports Add Client, Builder, ClientProtocol, ClientSession, and transport implementations for communicating with MCP servers. Supports tools, resources, prompts, and real-time progress/logging notifications. * refactor(examples): reorganize examples into server/ and client/ folders * feat: add SamplingRequestHandler for handling server sampling requests * feat: add setLoggingLevel method to control server logging verbosity * refactor: make progress token dependent on request ID * docs: Update server IP in usage instructions and add notes on sampling server requirements. * feat: add complete() method for completion/complete requests * refactor: properly parse and type initialize result * refactor: standardize method names * fix: revert changes to server related components * fix: revert changes to server related components * refactor: Restructure client transports and handlers into dedicated namespaces. * fix: cs and php-stan errors fixes(partial) * feat: Refactor request handlers to return `Response` or `Error` objects directly, adding a `SamplingException` and error logging for sampling requests. * feat: Replace `ClientTransportInterface` with `TransportInterface` and move response result deserialization to client methods. * refactor: remove redundant timeout check for intialize on transports The processFiber that executes per tick while fiber is suspended already handles timeouts while waiting * feat: broaden symfony/http-client dependency to support Symfony 5.4 to 8.0 * Update examples/client/README.md Co-authored-by: Christopher Hertel <mail@christopher-hertel.de> * Update examples/client/README.md Co-authored-by: Christopher Hertel <mail@christopher-hertel.de> * refactor: remove outgoing message queue from session and simplify transport send method to directly dispatch messages. * refactor: Replace ClientSession with ClientState for clearer intent on runtime state management * refactor: rename connectAndInitialize to connect for consistency * chore: cs fix * chore: use SamplingCallbackInterface instead of a closure for sampling request handler --------- Co-authored-by: Christopher Hertel <mail@christopher-hertel.de>

* HTTP Client Example.
|
|
*
|
|
* This example demonstrates how to use the MCP client with an HTTP transport
|
|
* to communicate with a remote MCP server over HTTP.
|
|
*
|
|
* Usage: php examples/client/http_discovery_calculator.php
|
|
*
|
|
* Before running, start an HTTP MCP server:
|
|
* php -S localhost:8080 examples/server/http-discovery-calculator/server.php
