Implementation Reference

• src/service/hex.ts:45-55 (handler)

  The async handler function that encodes the input string to hexadecimal using HexUtil.stringToHex and returns it as text content.

  async ({ content }: { content: string }) => {
      const result = HexUtil.stringToHex(content);
      return {
          content: [
              {
                  type: "text",
                  text: result,
              },
          ],
      };
  }

• src/service/hex.ts:42-44 (schema)

  Zod input schema defining the 'content' parameter as a string to encode to hex.

  {
      content: z.string().describe("text to encode"),
  },

• src/service/hex.ts:40-56 (registration)

  Registration of the 'hex_encode' tool using server.tool, including name, description, schema, and handler.

      "hex_encode",
      "encode text to hex",
      {
          content: z.string().describe("text to encode"),
      },
      async ({ content }: { content: string }) => {
          const result = HexUtil.stringToHex(content);
          return {
              content: [
                  {
                      type: "text",
                      text: result,
                  },
              ],
          };
      }
  );

• src/service/hex.ts:13-17 (helper)

  Core helper method that performs the string to hex encoding logic used by the tool handler.

  static stringToHex(str: string): string {
      return Array.from(str)
          .map(char => char.charCodeAt(0).toString(16).padStart(2, '0'))
          .join('');
  }
