Implementation Reference

• index.ts:84-92 (handler)

  Handler logic for the 'get_featured_coins' tool: sets the API URL to fetch featured coins from pump.fun and returns the JSON data.

  case "get_featured_coins":
     url = PUMP_FUN_API_URL+'/coins/for-you';
     return {
        content: [{
          type: "text",
          text: JSON.stringify((await fetchPumpFunData(url, args)))
        }],
        isError: false,
    };

• index.ts:18-25 (schema)

  Input schema for the 'get_featured_coins' tool, defining optional parameters: offset, limit, includeNsfw.

  inputSchema: {
      type: "object",
      properties: {
          offset: { type: "number", description: "The offset to start from (default: 0)", default: 0 },
          limit: { type: "number", description: "The number of coins to return (default: 24)", default: 24 },
          includeNsfw: { type: "boolean", description: "Include NSFW coins (default: true)", default: true },
      }
  },

• index.ts:15-26 (registration)

  Registration of the 'get_featured_coins' tool in the TOOLS array, including name, description, and schema.

  {
      name: "get_featured_coins",
      description: "Get a list of featured coins",
      inputSchema: {
          type: "object",
          properties: {
              offset: { type: "number", description: "The offset to start from (default: 0)", default: 0 },
              limit: { type: "number", description: "The number of coins to return (default: 24)", default: 24 },
              includeNsfw: { type: "boolean", description: "Include NSFW coins (default: true)", default: true },
          }
      },
  },

• index.ts:56-74 (helper)

  Helper function to make authenticated API requests to pump.fun endpoints, used by the get_featured_coins handler.

  async function fetchPumpFunData(url: string, params: any) {
      const headers = {
          'accept': '*/*',
          'accept-language': 'en-US,en;q=0.9',
          'content-type': 'application/json',
          'origin': 'https://pump.fun',
          'priority': 'u=1, i',
          'referer': 'https://pump.fun/',
          'sec-ch-ua': '"Chromium";v="134", "Not:A-Brand";v="24", "Google Chrome";v="134"',
          'sec-ch-ua-mobile': '?0',
          'sec-ch-ua-platform': '"macOS"',
          'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/134.0.0.0 Safari/537.36'
      };
      const response = await axios.get(url, { params, headers });
      if (response.status !== 200 || !response.data) {
          throw new Error(`Failed to fetch data: ${response.status}`);
      }
      return response.data;
  }

• index.ts:152-154 (registration)

  Registers the CallToolRequestSchema handler which dispatches to handleToolCall based on tool name, enabling execution of get_featured_coins.

  server.setRequestHandler(CallToolRequestSchema, async (request) =>
    handleToolCall(request.params.name, request.params.arguments ?? {})
  );
