Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "yieldagentx402": {
      "command": "npx",
      "args": [
        "-y",
        "agentx402-mcp-server"
      ],
      "env": {
        "YAX_API_KEY": "your-value",
        "YAX_AGENT_ID": "your-value",
        "YAX_MCP_ENDPOINT": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add yieldagentx402 --env YAX_API_KEY=your-value --env YAX_AGENT_ID=your-value --env YAX_MCP_ENDPOINT=your-value -- npx -y agentx402-mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "yieldagentx402": {
      "command": "npx",
      "args": [
        "-y",
        "agentx402-mcp-server"

        "YAX_AGENT_ID": "your-value",
        "YAX_MCP_ENDPOINT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "yieldagentx402": {

        "YAX_AGENT_ID": "your-value",
        "YAX_MCP_ENDPOINT": "your-value"
      }
    }

Common questions

Is Yieldagentx402 safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: YAX_API_KEY, YAX_AGENT_ID

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.4) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

The package is intentionally thin. Tool discovery and tool calls are provided by the public YieldAgentX402 MCP endpoint, so the local package stays truthful as the hosted server evolves.
