Implementation Reference

• src/index.ts:820-831 (handler)

  MCP tool handler for 'get_24h_volume': calls subgraph.get24HVolume() and returns JSON response with volumeUSD.

  case 'get_24h_volume': {
    const volume = await subgraph.get24HVolume();
    
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify({ volumeUSD: volume }, null, 2),
        },
      ],
    };
  }

• src/index.ts:255-262 (registration)

  Tool registration in ListTools handler, including name, description, and input schema (no parameters required).

    name: 'get_24h_volume',
    description: 'Get the 24-hour trading volume on SailFish DEX',
    inputSchema: {
      type: 'object',
      properties: {},
      required: [],
    },
  },

• src/subgraph.ts:386-400 (helper)

  Helper function get24HVolume() that fetches factory from subgraph and returns totalVolumeUSD as proxy for 24h volume.

  export async function get24HVolume(): Promise<string> {
    try {
      const factory = await getFactory();
      if (!factory) {
        throw new Error('Factory data not available');
      }
      
      // Note: This is a simplified approach. For more accurate 24h volume,
      // you would need to compare current volume with volume from 24h ago
      return factory.totalVolumeUSD;
    } catch (error) {
      console.error('Error calculating 24h volume:', error);
      throw error;
    }
  }
