Overview

Chapters

• 00:00 - 00:30: Introduction and Reproducing the Error This chapter introduces the issue of encountering a recurring error while using MCP clients with AI agents in NA10. A demonstration is provided to reproduce the error in the system. The goal is to scrape using the firewall MCP client, employing the command 'npx -y firecolm' and the expression 'fire call'.
• 00:30 - 01:00: Setting up the MCP Server In this chapter, the process of setting up the MCP server is discussed. The narrator starts by mentioning the necessity of an API key that is required for the setup. The chapter highlights that the setup process remains consistent across different MCP servers such as Brave. The narrator demonstrates this process by running certain operations to showcase the occurrence of an expected error. During the setup, an error occurs while trying to execute an operation, specifically highlighting an issue with file or directory access.
• 01:00 - 01:30: Solution Overview The chapter 'Solution Overview' provides a step-by-step guide on how to make a system function under any circumstances by utilizing the N10 node MCP. The process begins with adding the N10 node MCP, which is essential for using MCPS. It is noted that this component should have already been installed; if not, the transcript instructs to install it by typing 'NA10 nodes MCP' and clicking install. The guide directs returning to the editor for the next steps.
• 01:30 - 02:00: Installing the Required Packages The chapter discusses the installation of required packages, mentioning MCP clients and the MCP client tool, which are marked with a community icon. The chapter highlights a solution initially proposed by 'binding ox' and later refined by 'conf'. This solution provides a step-by-step guide to force the packages to work even if the typical configuration fails. The chapter follows this solution closely.
• 02:00 - 02:30: Locating Installation Paths The chapter titled 'Locating Installation Paths' discusses setting up installations using different servers, specifically focusing on Firecrow to demonstrate compatibility with multiple MCP servers. Initially, it involves stopping an NA10 instance through the command prompt (cmd) and then running the cmd as an administrator. The next step is to execute the command 'npm install -g general', which is crucial for naming any MCP installation path.
• 02:30 - 03:00: Adjusting Command Arguments This chapter covers the process of adjusting command arguments on a server, specifically using the example of a firewall called 'firewall mcp.' The user is advised to find the node installation path using the 'where node' command, typically in the program files on Windows. Additionally, opening a notepad to store this path for easy reference is suggested. The chapter hints at checking the npm installation as well, although the details are not fully provided.
• 03:00 - 03:30: Final Configuration The chapter titled 'Final Configuration' provides instructions on navigating the file system to find where npm installations are located on a computer. It explains how to use the command line to retrieve the npm path, guiding readers to access the user directory, then 'app data', followed by the 'roaming' directory, and finally 'npm'. Here, within the 'node modules', users can find all npm installations including recent ones like the 'firewall mcp'.
• 03:30 - 04:00: Testing the Setup In this chapter, the focus is on setting up the environment correctly. The key task involves locating a specific index file named 'this.index.gs', copying its path, and then using it strategically. Instead of using a predefined command with general paths, the chapter guides on using the actual path of 'nodejs' and 'index.js' directly from 'fireall mcp'. This approach is taken to ensure precise command execution and arguments handling.
• 04:00 - 04:30: Conclusion and Community Engagement In this section, the focus is on setting up and testing an MCP client. The client is prepared by creating new credentials and configuring necessary paths and arguments, including the node executable path and a specific argument to ignore a certain robot (-t). Within the environment settings, an expression is added which involves the fire crawl API key, indicating the configuration necessary for the client to function properly.

• 00:00 - 00:30 So you're trying to use MCP clients with AI agents inside of NA10. But whenever you are running your process, you are basically faced with the same error. Let's actually run the process here just so that you can see the same error that is going to be reproduced in my system. By the way, this is a really simple AI agent system. What I'm trying to do is basically being able to scrape. So I am trying to reach the firewall MCP client and here I am basically using the command npx then using the -y firecolm. And here I have the expression fire call
• 00:30 - 01:00 API key equals to my API key. So that is the way I'm trying to set up my MCP server. If you are using Brave or any other MCP server, it is going to be the same way. So here, let's close this and let me run in order for you to be able to see that I'm actually able to reproduce the error. So let's say list all tools I have. So it's going to go to my open AI chat model and then it is going to try to go to list tools and here it's going to have the error fail to execute operation. The file or directory does
• 01:00 - 01:30 not exist. So I'm going to show you step by step how you can basically force it to work on your own system whatever the circumstances. So first of all add the N10 node MCP just so that we can actually use MCPS. I suppose you should have already done it. So if you didn't do that, you absolutely have to install the N810 nodes MCP by simply writing NA10 nodes MCP. Then you understand and you click on install. Once you go back to the editor and you go here, you are
• 01:30 - 02:00 going to be able to find MCP clients and MCP client tool added in here with this little icon that's saying that these are packages from the community. Now let's actually go through the solution. So the solution had been proposed first by binding ox and then it was later refined by conf where they basically showed step by step how we can actually force it to work even if we cannot make it work with the usual configuration. So let's actually follow it step by step. In his solution he basically showed how to use
• 02:00 - 02:30 it with server brave search but what we are going to do is basically do it with firecrow just so that you can see how you can make it work with multiple MCP servers. All right. So the first thing that we are going to do is that we are going to go back to our cmd. We are going to stop the NA10 instance. We're going to close this and then we are going to open the cmd as admin. So let's run this as admin. And here what we are going to do is we are going to run npm install-g general. It's important. And then you are going to name whatever MCP
• 02:30 - 03:00 server that you are going to use. In my case it's going to be the firewall mcp. So I am just going to copy paste the firecroll-mcp in here. Now we are going to run where node. This is going to give us the path to where our node is installed which is in the program file if you are on windows like me. So let's go ahead and open a notepad. Place that in here just so that we can keep it. Let's run this command just to find where our npm installation go to. So
• 03:00 - 03:30 let's go back to the cmd and then npm-groot. This is going to give us the path where all of npm. So let's go ahead and actually access that path. Just go to users then go to your the username and then go to app data. Go to roaming and then go to npm. It's going to be here and then node modules. And this is where every installation go to. So as you can see here the installation that we have just done is going to be right inside of here in the firewall mcp. We
• 03:30 - 04:00 need to locate the this.index.gs GS which is going to be inside of here. So this file that we have here. So just right click on this and copy as path. Then let's go back here and keep it inside of here. And let's delete the double quotes. And now what we are going to do is instead of using the npx andy fireall mcp. What we are going to do is that we are going to use the actual path of nodejs and index.js from the fireall mcp as our command and arguments. So
• 04:00 - 04:30 let's go back. Let's have an MCP client in here just so that we can test it better. So this is our MCP client. Let's create a new credential. In our command, we are going to put this. So the the path to node executable. And then in the argument, we are going to put this. And then we're going to add ignore- robot-t. And then inside of the environment, just put expression in here. And then what we are going to put inside of here is of course the fire crawl API key. And then all you need to
• 04:30 - 05:00 do is save. And of course before doing that, we need to go back here and launch NA10. So let's launch NA10. So let's go back now. Let's name our credential firecroll MCP. As I said, it's going to be the same thing as any other MCP server. And as you can see here, it has been saved. And now if we run test step, we are going to see that our MCP client is going to work with no problems. And now if I come here and I change my credentials and connect to the fire call MCB that I have just created inside of here and also inside of here and then I
• 05:00 - 05:30 go to the chat and I say list all the available tools. You're going to see that my AI agent is working with no problems and I have been able to basically avoid that error all together. So that's it. Thank you guys so much for watching.
