Implementation Reference

src/index.js:389-407 (handler)

The handler function that executes the get_section_content tool. It calls the PDF parser's getContent method and formats the response as MCP content blocks.

async function getSectionContent(section_name, limit) {
  const content = pdfParser.getContent(section_name, limit);
  
  if (content.error) {
    return {
      content: [{
        type: "text",
        text: `Error: ${content.error}`
      }]
    };
  }

  return {
    content: [{
      type: "text",
      text: `Content from section "${content.section}":\n\n${content.content}`
    }]
  };
}

src/index.js:102-105 (schema)

Zod input schema validation for the get_section_content tool parameters.

const getSectionContentSchema = z.object({
  section_name: z.string().describe("Name of the section to retrieve content from"),
  limit: z.number().default(1000).describe("Maximum number of characters to return"),
});

src/index.js:186-190 (registration)

Tool registration in the MCP server's tool definitions array, including name, description, and input schema.

{
  name: "get_section_content",
  description: "Get content from a specific section of the food standards document",
  inputSchema: zodToJsonSchema(getSectionContentSchema)
},

src/pdf-parser.js:180-200 (helper)

Core helper method in PDFParser class that retrieves the actual content from a named section or all content, limiting by character count.

getContent(sectionName = null, limit = 1000) {
  if (!this.parsedContent) {
    return { error: 'PDF content not loaded' };
  }

  if (sectionName) {
    const section = this.sections[sectionName];
    if (!section) {
      return { error: `Section '${sectionName}' not found` };
    }
    return {
      section: sectionName,
      content: section.join('\n').substring(0, limit)
    };
  }

  return {
    section: 'all',
    content: this.parsedContent.substring(0, limit)
  };
}

src/tools.js:325-343 (handler)

Alternative class-based handler for get_section_content tool in GoodbookTools class, similar logic delegating to PDF parser.

async getSectionContent(sectionName, limit = 1000) {
  const content = this.pdfParser.getContent(sectionName, limit);
  
  if (content.error) {
    return {
      content: [{
        type: "text",
        text: `Error: ${content.error}`
      }]
    };
  }

  return {
    content: [{
      type: "text",
      text: `Content from section "${content.section}":\n\n${content.content}`
    }]
  };
}
