  The handler function for the create_label tool, which performs an API request to /api/labels to create a new label.

  async ({ name, color }) => {
      try {
          const data = await apiRequest("/api/labels", {
              method: "POST",
              body: JSON.stringify({ name, color }),
          });
  
          return {
              content: [{
                  type: "text",
                  text: `Label created successfully!\nID: ${data.label.id}\nName: ${data.label.name}\nColor: ${data.label.color}`
              }]
          };
      } catch (error) {
          return {
              content: [{
                  type: "text",
                  text: `Error creating label: ${error}`
              }],
              isError: true
          };
      }
  }

• src/index.ts:319-322 (schema)

  Input validation schema for the create_label tool using Zod.

  {

      color: z.enum(["gray", "red", "orange", "yellow", "green", "blue", "purple", "pink"]).optional().default("gray").describe("Label color"),
  },

• src/index.ts:317-346 (registration)

  Registration of the create_label tool using server.tool.

          color: z.enum(["gray", "red", "orange", "yellow", "green", "blue", "purple", "pink"]).optional().default("gray").describe("Label color"),
      },
      async ({ name, color }) => {
          try {

                  }]
              };
          } catch (error) {
