Implementation Reference
- src/index.ts:299-333 (handler)Primary handler implementation for the 'get_contract_info' MCP tool. Retrieves contract details (name, description, scriptHash, operations) from ContractService based on contractName and network, formats as JSON response.this.server.tool( 'get_contract_info', { contractName: z.string().describe('Contract name'), network: z.string().optional().describe('Network to use: "mainnet" or "testnet"'), }, async ({ contractName, network }) => { const contractService = await this.getContractService(network); try { const contract = contractService.getContract(contractName); const operations = contractService.getContractOperations(contractName); const scriptHash = contractService.getContractScriptHash(contractName); const result = { name: contract.name, description: contract.description, scriptHash, operations, network: contractService.getNetwork() }; return { content: [ { type: 'text', text: JSON.stringify(result, null, 2), }, ], }; } catch (error) { throw new Error(`Contract ${contractName} not found or not available on this network`); } } );
- src/index.ts:301-304 (schema)Input schema validation for get_contract_info tool using Zod schema: contractName (required string), network (optional string).{ contractName: z.string().describe('Contract name'), network: z.string().optional().describe('Network to use: "mainnet" or "testnet"'), },
- src/index.ts:299-333 (registration)Registers the 'get_contract_info' tool with the MCP McpServer instance.this.server.tool( 'get_contract_info', { contractName: z.string().describe('Contract name'), network: z.string().optional().describe('Network to use: "mainnet" or "testnet"'), }, async ({ contractName, network }) => { const contractService = await this.getContractService(network); try { const contract = contractService.getContract(contractName); const operations = contractService.getContractOperations(contractName); const scriptHash = contractService.getContractScriptHash(contractName); const result = { name: contract.name, description: contract.description, scriptHash, operations, network: contractService.getNetwork() }; return { content: [ { type: 'text', text: JSON.stringify(result, null, 2), }, ], }; } catch (error) { throw new Error(`Contract ${contractName} not found or not available on this network`); } } );
- Helper method in ContractService that returns detailed operations information for a specific contract, used by the tool handler.getContractOperations(contractName: string): any { try { // Get the contract definition const contract = this.getContract(contractName); // Return the operations with additional metadata return { operations: contract.operations, count: Object.keys(contract.operations).length, contractName: contract.name, network: this.network, available: this.isContractAvailable(contractName) }; } catch (error) { // If it's already a ContractError, rethrow it if (error instanceof ContractError) { throw error; } // Otherwise, wrap it in a ContractError const errorMessage = error instanceof Error ? error.message : String(error); throw new ContractError(`Failed to get contract operations: ${errorMessage}`); } }
