    Class ClientRegistration

    Handles OAuth Dynamic Client Registration (DCR) for MCP connections.

    Implements RFC 7591 DCR with fallback to pre-configured client credentials. Stores registrations in the database for reuse across connections.

    Features:

    • Automatic DCR when supported by authorization server
    • Fallback to pre-configured credentials
    • Registration persistence and reuse
    • Client secret expiration tracking
    const registration = new ClientRegistration();

    // Get or create client credentials
    const client = await registration.getOrRegisterClient(
        connectionId,
        serverId,
        metadata,
        {
            redirectUri: 'https://api.example.com/oauth/callback',
            scopes: 'read write'
        },
        contextUser
    );

    // Use client credentials in authorization request
    authUrl.searchParams.set('client_id', client.clientId);
