  this.server.tool(
      'list_adapters',
      'List all registered database adapters',
      {},
      () => {
          const adapters = [];
          for (const [id, adapter] of this.adapters) {
              adapters.push({
                  id,
                  type: adapter.type,
                  name: adapter.name,
                  version: adapter.version,
                  connected: adapter.isConnected()
              });
          }
  
          return {
              content: [{
                  type: 'text' as const,
                  text: JSON.stringify(adapters, null, 2)
              }]
