verses-by_chapter_number

Instructions

Implementation Reference

• src/handlers/verses.ts:21-67 (handler)

  The MCP tool handler function `handleVersesByChapterNumber` that validates input arguments using Zod schema, calls the versesService, logs the response or error, and returns MCP-compatible content blocks.

  export async function handleVersesByChapterNumber(args: any) {
    try {
      // Validate arguments
      const validatedArgs = versesByChapterNumberSchema.parse(args);
      
      // Call the service
      const result = await versesService.versesByChapterNumber(validatedArgs);
      
      // Log the response in verbose mode
      verboseLog('response', {
        tool: 'verses-by_chapter_number',
        result
      });
      
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(result, null, 2)
          }
        ]
      };
    } catch (error) {
      verboseLog('error', {
        tool: 'verses-by_chapter_number',
        error: error instanceof Error ? error.message : String(error)
      });
      
      if (error instanceof z.ZodError) {
        return {
          content: [{ 
            type: "text", 
            text: `Validation error: ${error.errors.map(e => `${e.path.join('.')}: ${e.message}`).join(', ')}`
          }],
          isError: true,
        };
      }
      
      return {
        content: [{ 
          type: "text", 
          text: `Error: ${error instanceof Error ? error.message : "Unknown error"}`
        }],
        isError: true,
      };
    }
  }

• src/schemas/verses.ts:27-33 (schema)

  Zod schema defining the input parameters for the tool, including required 'chapter_number' and optional common verse parameters (language, words, translations, etc.) and pagination.

   * Schema for verses-by_chapter_number
   */
  export const versesByChapterNumberSchema = z.object({
    chapter_number: z.string().describe("Chapter number (1-114)"),
    ...commonVerseParams,
    ...paginationParams,
  });

• src/server.ts:141-144 (registration)

  Registration of the tool in the server's listTools response, providing name, description, input schema, and usage examples.

  name: ApiTools.verses_by_chapter_number,
  description: "Get verses by Chapter / Surah number",
  inputSchema: zodToJsonSchema(versesSchemas.versesByChapterNumber),
  examples: toolExamples['verses-by_chapter_number'],

• src/server.ts:265-266 (registration)

  Dispatch registration in the server's callTool handler switch statement, routing calls to the specific handler function.

  case ApiTools.verses_by_chapter_number:
    return await handleVersesByChapterNumber(request.params.arguments);

• src/services/verses-service.ts:41-80 (helper)

  Core service logic that constructs the Quran.com API endpoint URL, passes parameters to makeApiRequest, and wraps the response in a structured format with success message.

  async versesByChapterNumber(params: z.infer<typeof versesByChapterNumberSchema>): Promise<VersesByChapterNumberResponse> {
    try {
      // Validate parameters
      const validatedParams = versesByChapterNumberSchema.parse(params);
      
      const url = `${API_BASE_URL}/verses/by_chapter/${validatedParams.chapter_number}`;
      
      // Make request to Quran.com API
      const data = await makeApiRequest(url, {
        language: validatedParams.language,
        words: validatedParams.words,
        translations: validatedParams.translations,
        audio: validatedParams.audio,
        tafsirs: validatedParams.tafsirs,
        word_fields: validatedParams.word_fields,
        translation_fields: validatedParams.translation_fields,
        fields: validatedParams.fields,
        page: validatedParams.page,
        per_page: validatedParams.per_page
      });
      
      return {
        success: true,
        message: "verses-by_chapter_number executed successfully",
        data
      };
    } catch (error) {
      verboseLog('error', {
        method: 'versesByChapterNumber',
        error: error instanceof Error ? error.message : String(error)
      });
      
      if (error instanceof z.ZodError) {
        throw new ApiError(`Validation error: ${error.errors.map(e => `${e.path.join('.')}: ${e.message}`).join(', ')}`, 400);
      }
      
      // Re-throw other errors
      throw error;
    }
  }
