Model Context Protocol
======================

Implements the [Model Context Protocol](https://modelcontextprotocol.io/) for the XP Framework.

Client
------

[](#client)

Connecting to an MCP server:

```
use io\modelcontextprotocol\McpClient;
use util\cmd\Console;

// Use streamable HTTP
$client= new McpClient('http://localhost:3001');

// Use standard I/O
$client= new McpClient(['docker', 'run', '--rm', '-i', 'mcp/time']);

$response= $client->call('tools/list');
Console::writeLine($response->value());
```

Server
------

[](#server)

Uses the [xp-forge/web](https://github.com/xp-forge/web) library:

```
use io\modelcontextprotocol\McpServer;
use io\modelcontextprotocol\server\{Tool, Param};
use web\Application;

class Test extends Application {

  public function routes() {
    return new McpServer([
      'greeting' => new class() {

        /** Sends a greeting */
        #[Tool]
        public function greet(#[Param('Whom to greet')] $name= null) {
          return 'Hello, '.($name ?? 'unknown user');
        }
      }
    ]);
  }
}
```

Run this via `xp -supervise web Test`.

Organizing code
---------------

[](#organizing-code)

MCP tools, resources and prompts may be organized into classes as follows:

```
namespace com\example\api;

use io\modelcontextprotocol\server\{Resource, Prompt, Tool, Param, Implementation};

#[Implementation]
class Greeting {

  /** Dynamic greeting for a user */
  #[Resource('greeting://user/{name}')]
  public function get($name) {
    return "Hello {$name}";
  }

  /** Greets users */
  #[Prompt]
  public function user(
    #[Param('Whom to greet')] $name,
    #[Param(type: ['type' => 'string', 'enum' => ['casual', 'friendly']])] $style= 'casual'
  ) {
    return "Write a {$style} greeting for {$name}";
  }

  /** Sends a given greeting by email */
  #[Tool]
  public function send(
    #[Param('Recipient email address')] $recipient,
    #[Param('The text to send')] $greeting
  ) {
    // TBI
  }
}}
```

The web application then becomes this:

```
use io\modelcontextprotocol\McpServer;
use web\Application;

class Test extends Application {

  public function routes() {
    return new McpServer('com.example.api');
  }
}
```

Authentication
--------------

[](#authentication)

To add OAuth2 authentication to your server, use the following:

```
use io\modelcontextprotocol\McpServer;
use io\modelcontextprotocol\server\{ImplementationsIn, OAuth2Gateway, Clients, UseSessions};
use web\Application;
use web\session\InFileSystem;

class Test extends Application {

  public function routes() {
    $clients= new class() extends Clients { /* TBI */ };

    $sessions= (new InFileSystem())->named('oauth');
    $gateway= new OAuth2Gateway('/oauth', $clients, new UseSessions($sessions));

    $auth= /* Some class extending web.auth.Authentication */;

    $server= new McpServer(new ImplementationsIn('impl'));
    return [
      '/mcp'   => $gateway->authenticate($server),
      '/oauth' => $gateway->flow($auth, $sessions),
      '/.well-known/oauth-protected-resource'   => $gateway->resource(),
      '/.well-known/oauth-authorization-server' => $gateway->metadata(),
    ];
  }
}
```
