Implementation Reference

• src/index.ts:932-991 (handler)

  The handler function that implements the mint_tokens tool logic. It retrieves the wallet, ensures connection, calculates raw amount based on decimals, creates destination token account if needed, and calls mintTo to mint tokens.
  async function handleMintTokens(args: any) { const { walletName, tokenMint, destinationAddress, amount } = args; const wallet = wallets.get(walletName); if (!wallet) { throw new Error(`Wallet '${walletName}' not found`); } ensureConnection(); const tokenMintPubkey = new PublicKey(tokenMint); const destinationPubkey = new PublicKey(destinationAddress); const mintInfo = await getMint(connection, tokenMintPubkey); const rawAmount = BigInt(Math.floor(amount * Math.pow(10, mintInfo.decimals))); const destinationTokenAccount = await getAssociatedTokenAddress( tokenMintPubkey, destinationPubkey ); // Check if destination token account exists, create if not try { await getAccount(connection, destinationTokenAccount); } catch { const transaction = new Transaction().add( createAssociatedTokenAccountInstruction( wallet.keypair.publicKey, destinationTokenAccount, destinationPubkey, tokenMintPubkey ) ); const { blockhash } = await connection.getLatestBlockhash(); transaction.recentBlockhash = blockhash; transaction.feePayer = wallet.keypair.publicKey; transaction.sign(wallet.keypair); await connection.sendTransaction(transaction, [wallet.keypair]); await new Promise(resolve => setTimeout(resolve, 2000)); // Wait for account creation } const signature = await mintTo( connection, wallet.keypair, tokenMintPubkey, destinationTokenAccount, wallet.keypair, rawAmount ); return { success: true, signature, amount, tokenMint: tokenMint, destination: destinationAddress, explorerUrl: `https://explorer.solana.com/tx/${signature}?cluster=${currentNetwork}` }; }
• src/index.ts:325-350 (registration)

  Tool registration in the tools array, defining the name, description, and input schema for the mint_tokens tool.
  { name: "mint_tokens", description: "Mint tokens to a specific account", inputSchema: { type: "object", properties: { walletName: { type: "string", description: "Name of the wallet with mint authority" }, tokenMint: { type: "string", description: "Token mint address" }, destinationAddress: { type: "string", description: "Destination wallet address" }, amount: { type: "number", description: "Amount of tokens to mint (in token units, not raw)" } }, required: ["walletName", "tokenMint", "destinationAddress", "amount"] } },
• src/index.ts:1333-1334 (registration)

  Dispatch case in the main CallToolRequestSchema handler that routes mint_tokens calls to the handleMintTokens function.
  case "mint_tokens": result = await handleMintTokens(args);
