VS Code Playwright browser_tab_list

How to: VS Code Playwright browser_tab_list

client:VS Code transport:stdio tool:browser_tab_list

Add Playwright to VS Code

  1. 01

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

{
  "servers": {
    "playwright-mcp": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@playwright/mcp"
      ]
    }
  }
}
  1. 02

    Save the file and restart VS Code.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Playwright'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

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.
