DexPaprika MCP Server

Instructions

Implementation Reference

• src/index.js:155-158 (handler)

  Handler function that fetches token details from the DexPaprika API endpoint and formats the response for MCP.

  async ({ network, tokenAddress }) => {
    const data = await fetchFromAPI(`/networks/${network}/tokens/${tokenAddress}`);
    return formatMcpResponse(data);
  }

• src/index.js:151-154 (schema)

  Zod schema defining input parameters: network (string) and tokenAddress (string).

  {
    network: z.string().describe('Network ID from getNetworks (e.g., "ethereum", "solana")'),
    tokenAddress: z.string().describe('Token address or identifier')
  },

• src/index.js:148-159 (registration)

  Registers the getTokenDetails tool using server.tool, including name, description, schema, and handler function.

  server.tool(
    'getTokenDetails',
    'Get detailed information about a specific token on a network. First use getNetworks to get valid network IDs.',
    {
      network: z.string().describe('Network ID from getNetworks (e.g., "ethereum", "solana")'),
      tokenAddress: z.string().describe('Token address or identifier')
    },
    async ({ network, tokenAddress }) => {
      const data = await fetchFromAPI(`/networks/${network}/tokens/${tokenAddress}`);
      return formatMcpResponse(data);
    }
  );

• src/index.js:10-34 (helper)

  Shared helper function used by getTokenDetails 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;
    }
  }

• src/index.js:37-46 (helper)

  Shared helper function used by getTokenDetails to format API response for MCP protocol.

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