DexPaprika (CoinPaprika)

Instructions

Implementation Reference

• src/index.js:114-117 (handler)

  The async handler function that executes the getNetworkPools tool logic by constructing the API endpoint and fetching data using fetchFromAPI, then formatting the response.

  async ({ network, page, limit, sort, orderBy }) => {
    const data = await fetchFromAPI(`/networks/${network}/pools?page=${page}&limit=${limit}&sort=${sort}&order_by=${orderBy}`);
    return formatMcpResponse(data);
  }

• src/index.js:107-113 (schema)

  Zod schema defining the input parameters for the getNetworkPools tool, including required network and optional pagination/sort parameters.

  {
    network: z.string().describe('Network ID from getNetworks (required) - e.g., "ethereum", "solana"'),
    page: z.number().optional().default(0).describe('Page number for pagination'),
    limit: z.number().optional().default(10).describe('Number of items per page (max 100)'),
    sort: z.enum(['asc', 'desc']).optional().default('desc').describe('Sort order'),
    orderBy: z.enum(['volume_usd', 'price_usd', 'transactions', 'last_price_change_usd_24h', 'created_at']).optional().default('volume_usd').describe('Field to order by')
  },

• src/index.js:104-118 (registration)

  The server.tool registration for the getNetworkPools MCP tool, including name, description, schema, and inline handler function.

  server.tool(
    'getNetworkPools',
    'PRIMARY POOL FUNCTION: Get top liquidity pools on a specific network. This is the MAIN way to get pool data - there is NO global pools function. Use this instead of any "getTopPools" or "getAllPools" concepts.',
    {
      network: z.string().describe('Network ID from getNetworks (required) - e.g., "ethereum", "solana"'),
      page: z.number().optional().default(0).describe('Page number for pagination'),
      limit: z.number().optional().default(10).describe('Number of items per page (max 100)'),
      sort: z.enum(['asc', 'desc']).optional().default('desc').describe('Sort order'),
      orderBy: z.enum(['volume_usd', 'price_usd', 'transactions', 'last_price_change_usd_24h', 'created_at']).optional().default('volume_usd').describe('Field to order by')
    },
    async ({ network, page, limit, sort, orderBy }) => {
      const data = await fetchFromAPI(`/networks/${network}/pools?page=${page}&limit=${limit}&sort=${sort}&order_by=${orderBy}`);
      return formatMcpResponse(data);
    }
  );

• src/index.js:37-46 (helper)

  Helper function used by getNetworkPools handler to format the API response into MCP-compatible structure.

  function formatMcpResponse(data) {
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(data)
        }
      ]
    };
  }

• src/index.js:10-34 (helper)

  Shared helper function used by getNetworkPools to make API requests to DexPaprika with error handling.

  async function fetchFromAPI(endpoint) {
    try {
      const response = await fetch(`${API_BASE_URL}${endpoint}`);
      if (!response.ok) {
        if (response.status === 410) {
          throw new Error(
            'This endpoint has been permanently removed. Please use network-specific endpoints instead. ' +
            'For example, use /networks/{network}/pools instead of /pools. ' +
            'Get available networks first using the getNetworks function.'
          );
        }
        if (response.status === 429) {
          throw new Error(
            'Rate limit exceeded. You have reached the maximum number of requests allowed for the free tier. ' +
            'To increase your rate limits and access additional features, please consider upgrading to a paid plan at https://docs.dexpaprika.com/'
          );
        }
        throw new Error(`API request failed with status ${response.status}`);
      }
      return await response.json();
    } catch (error) {
      console.error(`Error fetching from API: ${error.message}`);
      throw error;
    }
  }
