Rootstock MCP Server

Instructions

Implementation Reference

• src/index.ts:926-948 (handler)

  MCP tool handler function that gets the current wallet, calls rootstockClient.deployERC721Token with parameters, and returns formatted success response with contract details.
  private async handleDeployERC721Token(params: DeployERC721Params) { try { const wallet = this.walletManager.getCurrentWallet(); const result = await this.rootstockClient.deployERC721Token( wallet, params.name, params.symbol, params.mintable || false, params.gasLimit, params.gasPrice ); return { content: [ { type: 'text', text: `ERC721 NFT Contract Deployed Successfully!\n\nContract Address: ${result.contractAddress}\nTransaction Hash: ${result.transactionHash}\nName: ${result.name}\nSymbol: ${result.symbol}\nDeployer: ${result.deployer}${result.gasUsed ? `\nGas Used: ${result.gasUsed}` : ''}${result.blockNumber ? `\nBlock Number: ${result.blockNumber}` : ''}`, }, ], }; } catch (error) { throw new Error(`Failed to deploy ERC721 token: ${error}`); }
• src/index.ts:489-516 (registration)

  Tool registration in getAvailableTools() array, defining name, description, and input schema matching DeployERC721Params.
  name: 'deploy_erc721_token', description: 'Deploy a new ERC721 (NFT) token contract', inputSchema: { type: 'object', properties: { name: { type: 'string', description: 'NFT collection name (e.g., "My NFT Collection")', }, symbol: { type: 'string', description: 'NFT collection symbol (e.g., "MYNFT")', }, mintable: { type: 'boolean', description: 'Whether the NFT should be mintable (default: false)', }, gasLimit: { type: 'string', description: 'Optional gas limit', }, gasPrice: { type: 'string', description: 'Optional gas price', }, }, required: ['name', 'symbol'], },
• src/types.ts:218-223 (schema)

  TypeScript interface defining input parameters for deploy_erc721_token tool.
  export interface DeployERC721Params { name: string; symbol: string; mintable?: boolean; gasLimit?: string; gasPrice?: string;
• src/rootstock-client.ts:592-656 (helper)

  Core helper method in RootstockClient that performs the actual ERC721 contract deployment using ethers.js ContractFactory with pre-compiled ABI/bytecode.
  async deployERC721Token( wallet: ethers.Wallet | ethers.HDNodeWallet, name: string, symbol: string, mintable: boolean = false, gasLimit?: string, gasPrice?: string ): Promise<ERC721DeploymentResponse> { try { const connectedWallet = wallet.connect(this.getProvider()); // Check wallet balance first const balance = await this.getProvider().getBalance(wallet.address); console.log(`Wallet balance: ${ethers.formatEther(balance)} ${this.getCurrencySymbol()}`); if (balance === 0n) { throw new Error(`Wallet has no funds for deployment. Please fund the wallet: ${wallet.address}`); } // Get pre-compiled ERC721 contract console.log('Loading ERC721 contract...'); const compiled = this.getCompiledERC721Contract(mintable); console.log('Contract loaded successfully'); // Create contract factory const contractFactory = new ethers.ContractFactory( compiled.abi, compiled.bytecode, connectedWallet ); console.log(`Deploying ERC721 contract: ${name} (${symbol})`); // Deploy contract with parameters: name, symbol const contract = await contractFactory.deploy( name, symbol, { gasLimit: gasLimit ? BigInt(gasLimit) : undefined, gasPrice: gasPrice ? BigInt(gasPrice) : undefined, } ); console.log('Contract deployment transaction sent, waiting for confirmation...'); // Wait for deployment const receipt = await contract.deploymentTransaction()?.wait(); console.log('ERC721 contract deployed successfully!'); const contractAddress = await contract.getAddress(); console.log(`Contract address: ${contractAddress}`); return { contractAddress, transactionHash: contract.deploymentTransaction()?.hash || '', name, symbol, deployer: wallet.address, gasUsed: receipt?.gasUsed.toString(), blockNumber: receipt?.blockNumber, }; } catch (error) { console.error('ERC721 deployment error:', error); throw new Error(`Failed to deploy ERC721 token: ${error}`); }
