Implementation Reference

• index.js:19-58 (handler)

  Handler function that generates the specified number (1-100) of random Ethereum wallets using ethers.Wallet.createRandom(). Each wallet includes address, privateKey, and mnemonic phrase. Returns a JSON-formatted text response or error.

  async ({ count }) => {
    try {
      const wallets = [];
      // Generate the specified number of random wallets
      for (let i = 0; i < count; i++) {
        const wallet = ethers.Wallet.createRandom();
        wallets.push({
          address: wallet.address,
          privateKey: wallet.privateKey,
          mnemonic: wallet.mnemonic.phrase,
        });
      }
  
      // Return the generated wallets in JSON format
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(
              wallets,
              null,
              2
            ),
          },
        ],
        isError: false,
      };
    } catch (error) {
      // Return an error message if wallet generation fails
      return {
        content: [
          {
            type: "text",
            text: `Error generating wallets: ${error.message}`,
          },
        ],
        isError: true,
      };
    }
  }

• index.js:16-18 (schema)

  Zod input schema: 'count' parameter (number, min 1, max 100, default 1).

  z.object({
    count: z.number().min(1).max(100).default(1), // Limit the number of wallets to generate (1-100)
  }),

• index.js:13-59 (registration)

  MCP server tool registration for 'generateWallets': includes name, description, Zod schema, and handler function.

  server.tool(
    "generateWallets",
    "Batch-generating ethereum wallets",
    z.object({
      count: z.number().min(1).max(100).default(1), // Limit the number of wallets to generate (1-100)
    }),
    async ({ count }) => {
      try {
        const wallets = [];
        // Generate the specified number of random wallets
        for (let i = 0; i < count; i++) {
          const wallet = ethers.Wallet.createRandom();
          wallets.push({
            address: wallet.address,
            privateKey: wallet.privateKey,
            mnemonic: wallet.mnemonic.phrase,
          });
        }
  
        // Return the generated wallets in JSON format
        return {
          content: [
            {
              type: "text",
              text: JSON.stringify(
                wallets,
                null,
                2
              ),
            },
          ],
          isError: false,
        };
      } catch (error) {
        // Return an error message if wallet generation fails
        return {
          content: [
            {
              type: "text",
              text: `Error generating wallets: ${error.message}`,
            },
          ],
