Implementation Reference

• src/index.ts:297-326 (handler)

  The core handler function `getMarketSummary()` that fetches market summary data from the CSE API (https://www.cse.lk/api/marketSummery) and returns trade volume, share volume, and trade date.

  async function getMarketSummary() {
    try {
      const response = await axios.post(
        'https://www.cse.lk/api/marketSummery',
        {},
        {
          headers: {
            'Content-Type': 'application/json'
          },
          timeout: 10000
        }
      );
      
      const data = response.data || {};
      
      return {
        tradeVolume: data.tradeVolume,
        shareVolume: data.shareVolume,
        tradeDate: data.tradeDate ? new Date(data.tradeDate).toISOString() : null
      };
    } catch (error: any) {
      if (error.code === 'ECONNABORTED') {
        throw new Error('Request timed out. Please try again.');
      } else if (error.response) {
        throw new Error(`API error: ${error.response.status} - ${error.response.statusText}`);
      } else {
        throw new Error(`Network error: ${error.message}`);
      }
    }
  }

• src/index.ts:598-602 (schema)

  The schema/registration for the 'get_market_summary' tool, defining its title, description, and empty inputSchema (no inputs required).

    inputSchema: {}
  },

• src/index.ts:596-629 (registration)

  The registration of the 'get_market_summary' tool on the MCP server via `server.registerTool()`, including the handler that calls getMarketSummary() and formats the response.

  server.registerTool(
    "get_market_summary",
    {
      title: "Get Market Summary",
      description: "Get the overall market summary including total trade volume, share volume, and trade date.",
      inputSchema: {}
    },
    async () => {
      try {
        const marketSummary = await getMarketSummary();
        
        return {
          content: [{
            type: "text",
            text: JSON.stringify({
              title: "Market Summary",
              tradeVolume: marketSummary.tradeVolume ? `Rs. ${marketSummary.tradeVolume.toLocaleString()}` : 'N/A',
              shareVolume: marketSummary.shareVolume?.toLocaleString() || 'N/A',
              tradeDate: marketSummary.tradeDate || 'N/A',
              lastUpdated: new Date().toISOString()
            }, null, 2)
          }]
        };
      } catch (error: any) {
        return {
          content: [{
            type: "text",
            text: `Error fetching market summary: ${error.message}`
          }],
          isError: true
        };
      }
    }
