Implementation Reference

• src/tools.ts:362-401 (handler)

  Inline handler for the 'get-labels' MCP tool. Retrieves all Gmail labels by executing the Composio 'GMAIL_GET_LABELS' action via VercelAIToolSet, formats the list, and returns a text response.

  server.tool("get-labels", "Get all Gmail labels", {}, async (args, extra) => {
      try {
          const userAddress = "default-user";
          
          const result = await toolset.executeAction({
              action: "GMAIL_GET_LABELS",
              entityId: userAddress,
              params: {}
          });
          
          if (result.successful) {
              const labels = result.data?.response_data as any;
              const labelList = labels.labels?.map((label: any) => 
                  `• ${label.name} (${label.id})`
              ).join('\n') || 'No labels found';
              
              return {
                  content: [{ 
                      type: "text", 
                      text: `🏷️ Labels retrieved successfully!\n\n${labelList}\n\nTotal: ${labels.labels?.length || 0} labels` 
                  }],
              };
          } else {
              return {
                  content: [{ 
                      type: "text", 
                      text: `❌ Failed to get labels: ${result.error || 'Unknown error'}` 
                  }],
              };
          }
      } catch (error) {
          console.error('Error getting labels:', error);
          return {
              content: [{ 
                  type: "text", 
                  text: `Error getting labels: ${error instanceof Error ? error.message : String(error)}` 
              }],
          };
      }
  });

• src/tools.ts:362-401 (registration)

  Registers the 'get-labels' tool with MCP server using server.tool(), including empty schema {} and inline handler.

  server.tool("get-labels", "Get all Gmail labels", {}, async (args, extra) => {
      try {
          const userAddress = "default-user";
          
          const result = await toolset.executeAction({
              action: "GMAIL_GET_LABELS",
              entityId: userAddress,
              params: {}
          });
          
          if (result.successful) {
              const labels = result.data?.response_data as any;
              const labelList = labels.labels?.map((label: any) => 
                  `• ${label.name} (${label.id})`
              ).join('\n') || 'No labels found';
              
              return {
                  content: [{ 
                      type: "text", 
                      text: `🏷️ Labels retrieved successfully!\n\n${labelList}\n\nTotal: ${labels.labels?.length || 0} labels` 
                  }],
              };
          } else {
              return {
                  content: [{ 
                      type: "text", 
                      text: `❌ Failed to get labels: ${result.error || 'Unknown error'}` 
                  }],
              };
          }
      } catch (error) {
          console.error('Error getting labels:', error);
          return {
              content: [{ 
                  type: "text", 
                  text: `Error getting labels: ${error instanceof Error ? error.message : String(error)}` 
              }],
          };
      }
  });
