Implementation Reference

• src/index.ts:527-545 (handler)

  The main execution logic for the 'create_wallet' tool. It validates the wallet name, generates a new Solana Keypair, stores it in the in-memory wallets map, and returns the wallet details including base58-encoded private key.

  async function handleCreateWallet(args: any) {
    const { name } = args;
    
    if (wallets.has(name)) {
      throw new Error(`Wallet with name '${name}' already exists`);
    }
  
    const keypair = Keypair.generate();
    wallets.set(name, { keypair, name });
  
    return {
      success: true,
      wallet: {
        name,
        address: keypair.publicKey.toString(),
        privateKey: bs58.encode(keypair.secretKey)
      }
    };
  }

• src/index.ts:77-86 (schema)

  Input schema definition for the 'create_wallet' tool, specifying a required 'name' string parameter.

  inputSchema: {
    type: "object",
    properties: {
      name: {
        type: "string",
        description: "Name for the wallet"
      }
    },
    required: ["name"]
  }

• src/index.ts:74-87 (registration)

  Registration of the 'create_wallet' tool in the tools array, which is returned by ListToolsRequestSchema handler. Includes name, description, and input schema.

  {
    name: "create_wallet",
    description: "Create a new Solana wallet",
    inputSchema: {
      type: "object",
      properties: {
        name: {
          type: "string",
          description: "Name for the wallet"
        }
      },
      required: ["name"]
    }
  },

• src/index.ts:1285-1287 (registration)

  Dispatch registration in the switch statement of the CallToolRequestSchema handler, routing 'create_wallet' calls to the handleCreateWallet function.

  case "create_wallet":
    result = await handleCreateWallet(args);
    break;
