Zetrix MCP Server

Instructions

Implementation Reference

• src/zetrix-client.ts:518-535 (handler)

  Core handler function in ZetrixClient that serializes transaction data by calling the RPC endpoint /getTransactionBlob and handles errors.

  async getTransactionBlob(transaction: any): Promise<ZetrixTransactionBlob> {
    try {
      const response = await this.client.post("/getTransactionBlob", transaction);
  
      if (response.data.error_code !== 0) {
        throw new Error(
          response.data.error_desc || `API Error: ${response.data.error_code}`
        );
      }
  
      return response.data.result;
    } catch (error) {
      if (axios.isAxiosError(error)) {
        throw new Error(`Failed to get transaction blob: ${error.message}`);
      }
      throw error;
    }
  }

• src/index.ts:268-281 (registration)

  MCP tool registration defining the name, description, and input schema.

  {
    name: "zetrix_get_transaction_blob",
    description: "Serialize transaction data into hexadecimal format",
    inputSchema: {
      type: "object",
      properties: {
        transaction: {
          type: "object",
          description: "Transaction object with source_address, nonce, fee_limit, gas_price, operations",
        },
      },
      required: ["transaction"],
    },
  },

• src/index.ts:271-280 (schema)

  Input schema for validating the transaction object parameter.

  inputSchema: {
    type: "object",
    properties: {
      transaction: {
        type: "object",
        description: "Transaction object with source_address, nonce, fee_limit, gas_price, operations",
      },
    },
    required: ["transaction"],
  },

• src/index.ts:987-999 (handler)

  MCP server dispatch handler that receives the tool call and delegates to ZetrixClient.getTransactionBlob.

  case "zetrix_get_transaction_blob": {
    if (!args) {
      throw new Error("Missing arguments");
    }
    const result = await zetrixClient.getTransactionBlob(args.transaction);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(result, null, 2),
        },
      ],
    };
