      return {
        content: [
          { 
            type: 'text', 
            text: JSON.stringify(actions, null, 2) 
          }
        ]
      };
    } catch (error) {
      return {
        content: [
          { 
            type: 'text', 
            text: `Error listing actions: ${error.message}`
