get_cosmos_transaction

Instructions

Implementation Reference

• src/handlers/cosmos-handlers.ts:518-534 (handler)

  MCP tool handler case: extracts parameters (blockchain, txHash, network) from args and calls cosmosService.getTransaction, formats result as MCP response.

  case 'get_cosmos_transaction': {
    const blockchain = args?.blockchain as string;
    const txHash = args?.txHash as string;
    const network = (args?.network as 'mainnet' | 'testnet') || 'mainnet';
  
    const result = await cosmosService.getTransaction(blockchain, txHash, network);
  
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(result, null, 2),
        },
      ],
      isError: !result.success,
    };
  }

• src/handlers/cosmos-handlers.ts:186-207 (schema)

  Tool schema definition including name, description, and inputSchema for validation.

    name: 'get_cosmos_transaction',
    description: 'Get Cosmos transaction by hash',
    inputSchema: {
      type: 'object',
      properties: {
        blockchain: {
          type: 'string',
          description: 'Blockchain name',
        },
        txHash: {
          type: 'string',
          description: 'Transaction hash',
        },
        network: {
          type: 'string',
          enum: ['mainnet', 'testnet'],
          description: 'Network type (defaults to mainnet)',
        },
      },
      required: ['blockchain', 'txHash'],
    },
  },

• src/services/cosmos-service.ts:231-247 (helper)

  Core implementation: constructs Cosmos REST API URL for transaction by hash and fetches via internal fetchRest method.

  async getTransaction(
    blockchain: string,
    txHash: string,
    network: 'mainnet' | 'testnet' = 'mainnet'
  ): Promise<EndpointResponse> {
    try {
      const baseUrl = this.getRestUrl(blockchain, network);
      const url = `${baseUrl}/cosmos/tx/v1beta1/txs/${txHash}`;
  
      return this.fetchRest(url);
    } catch (error) {
      return {
        success: false,
        error: error instanceof Error ? error.message : 'Failed to get Cosmos transaction',
      };
    }
  }

• src/index.ts:88-101 (registration)

  Registers all tool schemas by collecting from registerCosmosHandlers (line 98) into tools array used for ListTools response.

  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 (registration)

  Registers tool execution handler by dispatching CallToolRequest to handleCosmosTool (line 124).

  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));
