Implementation Reference

• src/index.ts:1058-1084 (handler)

  The main handler function that performs the thaw operation on a token account using the SPL token library's thawAccount function. It validates the wallet, sets up the connection, and returns the transaction signature.

  async function handleThawAccount(args: any) {
    const { walletName, tokenMint, accountAddress } = args;
  
    const wallet = wallets.get(walletName);
    if (!wallet) {
      throw new Error(`Wallet '${walletName}' not found`);
    }
  
    ensureConnection();
    const tokenMintPubkey = new PublicKey(tokenMint);
    const accountPubkey = new PublicKey(accountAddress);
  
    const signature = await thawAccount(
      connection,
      wallet.keypair,
      accountPubkey,
      tokenMintPubkey,
      wallet.keypair
    );
  
    return {
      success: true,
      signature,
      accountAddress,
      explorerUrl: `https://explorer.solana.com/tx/${signature}?cluster=${currentNetwork}`
    };
  }

• src/index.ts:395-416 (schema)

  The input schema defining the parameters for the thaw_account tool: walletName, tokenMint, and accountAddress.

  {
    name: "thaw_account",
    description: "Thaw a frozen token account to allow transfers",
    inputSchema: {
      type: "object",
      properties: {
        walletName: {
          type: "string",
          description: "Name of the wallet with freeze authority"
        },
        tokenMint: {
          type: "string",
          description: "Token mint address"
        },
        accountAddress: {
          type: "string",
          description: "Address of the token account to thaw"
        }
      },
      required: ["walletName", "tokenMint", "accountAddress"]
    }
  },

• src/index.ts:1342-1344 (registration)

  Registration in the tool dispatch switch statement that routes calls to the handleThawAccount handler.

  case "thaw_account":
    result = await handleThawAccount(args);
    break;

• src/index.ts:1273-1275 (registration)

  The tools array (including thaw_account) is returned in the ListToolsRequest handler, registering the tool for discovery.

  server.setRequestHandler(ListToolsRequestSchema, async () => {
    return { tools };
  });

• src/index.ts:12-21 (helper)

  Import of the thawAccount function from @solana/spl-token library, used as the core utility in the handler.

  import {
    createTransferInstruction,
    getAssociatedTokenAddress,
    createAssociatedTokenAccountInstruction,
    getAccount,
    createMint,
    mintTo,
    burn,
    freezeAccount,
    thawAccount,
