Implementation Reference

• src/handlers/contract-handlers.ts:15-41 (schema)

  Defines the tool schema including input parameters for call_contract_view
  { name: 'call_contract_view', description: 'Call a read-only contract function', inputSchema: { type: 'object', properties: { blockchain: { type: 'string', description: 'Blockchain name', }, contractAddress: { type: 'string', description: 'Contract address', }, data: { type: 'string', description: 'Encoded function call data', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['blockchain', 'contractAddress', 'data'], }, },
• src/handlers/contract-handlers.ts:59-81 (handler)

  Handler logic for executing the call_contract_view tool, delegates to advancedBlockchain service
  case 'call_contract_view': { const blockchain = args?.blockchain as string; const contractAddress = args?.contractAddress as string; const data = args?.data as string; const network = (args?.network as 'mainnet' | 'testnet') || 'mainnet'; const result = await advancedBlockchain.callContractView( blockchain, contractAddress, data, network ); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2), }, ], isError: !result.success, }; }
• src/index.ts:88-101 (registration)

  Registers all tool schemas including call_contract_view via registerContractHandlers for the ListTools endpoint
  const tools: Tool[] = [ ...registerBlockchainHandlers(server, blockchainService), ...registerDomainHandlers(server, domainResolver), ...registerTransactionHandlers(server, advancedBlockchain), ...registerTokenHandlers(server, advancedBlockchain), ...registerMultichainHandlers(server, advancedBlockchain), ...registerContractHandlers(server, advancedBlockchain), ...registerUtilityHandlers(server, advancedBlockchain), ...registerEndpointHandlers(server, endpointManager), ...registerSolanaHandlers(server, solanaService), ...registerCosmosHandlers(server, cosmosService), ...registerSuiHandlers(server, suiService), ...registerDocsHandlers(server, docsManager), ];
• src/index.ts:114-126 (handler)

  Central tool dispatcher that routes call_contract_view to handleContractTool
  let result = (await handleBlockchainTool(name, args, blockchainService)) || (await handleDomainTool(name, args, domainResolver)) || (await handleTransactionTool(name, args, advancedBlockchain)) || (await handleTokenTool(name, args, advancedBlockchain)) || (await handleMultichainTool(name, args, advancedBlockchain)) || (await handleContractTool(name, args, advancedBlockchain)) || (await handleUtilityTool(name, args, advancedBlockchain)) || (await handleEndpointTool(name, args, endpointManager)) || (await handleSolanaTool(name, args, solanaService)) || (await handleCosmosTool(name, args, cosmosService)) || (await handleSuiTool(name, args, suiService)) || (await handleDocsTool(name, args, docsManager));
• src/services/advanced-blockchain-service.ts:486-512 (helper)

  Core implementation that performs the eth_call RPC to call the contract view function
  async callContractView( blockchain: string, contractAddress: string, data: string, network: 'mainnet' | 'testnet' = 'mainnet' ): Promise<EndpointResponse> { const service = this.blockchainService.getServiceByBlockchain(blockchain, network); if (!service) { return { success: false, error: `Blockchain service not found: ${blockchain} (${network})`, }; } return this.blockchainService.callRPCMethod( service.id, 'eth_call', [ { to: contractAddress, data: data, }, 'latest', ] ); }
