Implementation Reference

• src/index.ts:228-286 (handler)

  The core handler function that executes the get_page_content tool logic: fetches wiki page content via API, strips HTML, processes entities, and returns structured JSON response.

  private async getPageContent(args: any) {
    const { title, section } = args;
  
    const params: Record<string, string> = {
      action: 'parse',
      page: title,
      prop: 'text|sections|categories|links|externallinks',
      disablelimitreport: '1',
      disableeditsection: '1',
    };
  
    if (section !== undefined) {
      params.section = section.toString();
    }
  
    const data = await this.makeApiRequest(params);
  
    if (data.error) {
      throw new McpError(ErrorCode.InternalError, data.error.info);
    }
  
    const parse = data.parse;
    if (!parse) {
      throw new McpError(ErrorCode.InvalidRequest, `Page '${title}' not found`);
    }
  
    // Extract text content and remove HTML
    const htmlContent = parse.text['*'];
    const textContent = htmlContent
      .replace(/<script\b[^<]*(?:(?!<\/script>)<[^<]*)*<\/script>/gi, '')
      .replace(/<style\b[^<]*(?:(?!<\/style>)<[^<]*)*<\/style>/gi, '')
      .replace(/<[^>]*>/g, '')
      .replace(/ /g, ' ')
      .replace(/&/g, '&')
      .replace(/</g, '<')
      .replace(/>/g, '>')
      .replace(/"/g, '"')
      .replace(/'/g, "'")
      .replace(/\n\s*\n/g, '\n\n')
      .trim();
  
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify({
            title: parse.title,
            pageid: parse.pageid,
            content: textContent,
            categories: parse.categories?.map((cat: any) => cat['*']) || [],
            sections: parse.sections || [],
            internalLinks: parse.links?.map((link: any) => link['*']) || [],
            externalLinks: parse.externallinks || [],
            url: `${WIKI_BASE_URL}/${title.replace(/ /g, '_')}`,
          }, null, 2),
        },
      ],
    };
  }

• src/index.ts:82-99 (registration)

  Tool registration in the listTools handler, including name, description, and input schema definition.

  {
    name: 'get_page_content',
    description: 'Get the full content of a specific wiki page',
    inputSchema: {
      type: 'object',
      properties: {
        title: {
          type: 'string',
          description: 'The title of the wiki page',
        },
        section: {
          type: 'number',
          description: 'Optional section number to retrieve',
        },
      },
      required: ['title'],
    },
  },

• src/index.ts:171-172 (handler)

  Dispatch case in the central CallToolRequestSchema handler that routes calls to the getPageContent method.

  case 'get_page_content':
    return this.getPageContent(request.params.arguments);

• src/index.ts:43-58 (helper)

  Utility helper function used by getPageContent to perform API requests to the wiki endpoint.

  private async makeApiRequest(params: Record<string, string>): Promise<WikiResponse> {
    try {
      const response = await axios.get(API_ENDPOINT, {
        params: {
          format: 'json',
          ...params,
        },
      });
      return response.data;
    } catch (error) {
      throw new McpError(
        ErrorCode.InternalError,
        `Failed to make API request: ${error instanceof Error ? error.message : 'Unknown error'}`
      );
    }
  }
