VS Code X402 Helper MCP call_endpoint

How to: VS Code X402 Helper MCP call_endpoint

client:VS Code transport:streamable-http tool:call_endpoint

Add X402 Helper MCP to VS Code

  1. 01

    Open .vscode/mcp.json and merge this in. Keep any servers already there.

{
  "servers": {
    "mcp": {
      "type": "http",
      "url": "https://x402helper.xyz/mcp"
    }
  }
}
  1. 02

    Save the file and restart VS Code.

  2. 03

    Ask for something call_endpoint does. VS Code lists the server's tools on connect and calls call_endpoint itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that X402 Helper MCP's identifier in your config matches the one above exactly.

Requires agent mode. MCP: Open User Configuration puts the same block in every workspace. VS Code docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 28 October 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
