VS Code Web Fetch fetch_url

How to: VS Code Web Fetch fetch_url

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

Add Web Fetch to VS Code

01
Open .vscode/mcp.json and merge this in. Keep any servers already there.

{
  "servers": {
    "web-fetch": {
      "type": "http",
      "url": "https://gateway.pipeworx.io/web-fetch/mcp"
    }
  }
}

02
Save the file and restart VS Code.
03
Ask for something fetch_url does. VS Code lists the server's tools on connect and calls fetch_url itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that Web Fetch'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

Set these first

Web Fetch will not start until these are set, so fetch_url never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 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.
