get_food_safety_info

Instructions

Implementation Reference

• src/index.js:409-453 (handler)

  The core handler function that executes the get_food_safety_info tool. It generates safety-related search terms based on the input topic, searches the PDF content via pdfParser, removes duplicates, and returns formatted results.

  async function getFoodSafetyInfo(topic) {
    const safetyTerms = [
      topic,
      `безопасность ${topic}`,
      `гигиена ${topic}`,
      `санитария ${topic}`,
      `температура ${topic}`,
      `хранение ${topic}`,
      `safety ${topic}`,
      `hygiene ${topic}`,
      `sanitation ${topic}`,
      `temperature ${topic}`,
      `storage ${topic}`
    ];
  
    let allResults = [];
    for (const term of safetyTerms) {
      const results = pdfParser.searchContent(term);
      if (results.results) {
        allResults.push(...results.results);
      }
    }
  
    const uniqueResults = allResults.filter((result, index, self) => 
      index === self.findIndex(r => r.content === result.content)
    );
  
    let response = `Food safety information for "${topic}":\n\n`;
    
    if (uniqueResults.length === 0) {
      response += "No specific food safety information found for this topic.";
    } else {
      uniqueResults.slice(0, 8).forEach((result, index) => {
        response += `Safety guideline ${index + 1}:\n`;
        response += `${result.content}\n\n`;
      });
    }
  
    return {
      content: [{
        type: "text",
        text: response
      }]
    };
  }

• src/index.js:107-109 (schema)

  Zod schema used for input validation of the tool's 'topic' parameter.

  const getFoodSafetyInfoSchema = z.object({
    topic: z.string().describe("Specific food safety topic (temperature, storage, hygiene, etc.)"),
  });

• src/index.js:191-195 (registration)

  Registration of the tool in the MCP server's toolDefinitions array, including name, description, and derived JSON input schema.

  {
    name: "get_food_safety_info",
    description: "Get food safety information and hygiene standards",
    inputSchema: zodToJsonSchema(getFoodSafetyInfoSchema)
  },

• src/tools.js:345-389 (handler)

  Alternative class method implementation of the handler in GoodbookTools class, identical logic to the index.js version.

  async getFoodSafetyInfo(topic) {
    const safetyTerms = [
      topic,
      `безопасность ${topic}`,
      `гигиена ${topic}`,
      `санитария ${topic}`,
      `температура ${topic}`,
      `хранение ${topic}`,
      `safety ${topic}`,
      `hygiene ${topic}`,
      `sanitation ${topic}`,
      `temperature ${topic}`,
      `storage ${topic}`
    ];
  
    let allResults = [];
    for (const term of safetyTerms) {
      const results = this.pdfParser.searchContent(term);
      if (results.results) {
        allResults.push(...results.results);
      }
    }
  
    const uniqueResults = allResults.filter((result, index, self) => 
      index === self.findIndex(r => r.content === result.content)
    );
  
    let response = `Food safety information for "${topic}":\n\n`;
    
    if (uniqueResults.length === 0) {
      response += "No specific food safety information found for this topic.";
    } else {
      uniqueResults.slice(0, 8).forEach((result, index) => {
        response += `Safety guideline ${index + 1}:\n`;
        response += `${result.content}\n\n`;
      });
    }
  
    return {
      content: [{
        type: "text",
        text: response
      }]
    };
  }

• src/tools.js:82-95 (registration)

  Inline JSON schema and registration in the getToolDefinitions() method of GoodbookTools class.

  {
    name: "get_food_safety_info",
    description: "Get food safety information and hygiene standards",
    inputSchema: {
      type: "object",
      properties: {
        topic: {
          type: "string",
          description: "Specific food safety topic (temperature, storage, hygiene, etc.)"
        }
      },
      required: ["topic"]
    }
  },
