Versions 0.0.19 and 0.0.20 failing to load in Cursor

[bordoni]

With this:

    "playwright": {
      "command": "npx",
      "args": [
        "@playwright/mcp@latest"
      ]
    }

Originally I was on version 18.17 of Node, but it seems like this version requires 20+ so I updated but now it's just not running.

When trying to reload via the Cursor UI:

2025-05-03 20:24:12.741 [info] ight: Handling ReloadClient action

With v0.0.18 it works:

    "playwright": {
      "command": "npx",
      "args": [
        "@playwright/mcp@v0.0.18"
      ]
    },

What's your Cursor version? And Node that Cursor uses?

Same for me.
Cursor version: 0.49.6
Node (Cursor) version: 20.18.3

My guess is that there is an older Node.js installed on your system which gets picked up. Cursor's MCP loader is most likely not activating nvm etc. Maybe Node.js from brew? Make sure to update this to latest 18.X or more recent (like 22.X). Cursor has also some more verbose logs here.

I also encountered the same problem. Before the 0.0.19 and 0.0.20 versions were released, using @playwright/mcp@latest could start mcp normally. Yesterday, it suddenly stopped working, and now I can only start it using version 18

I have the same issue. It works on version 18, but doesn’t work on versions 19 and 20.
node v20.9.0
Cursor version: 0.49.6

@wenhuiyang-luck @lindon0390
In my side it was solved after updating my system nvm to use node 22

[mxschmitt]

We just published 0.0.22 - could you try that? @playwright/mcp@v0.0.22

[lindon0390]

node v20.9.0
Cursor version: 0.49.6

Oh so we area talking about a v22 compatibility, cool I am ok with that requirement, but lets make sure we call it out on package.json

Version @playwright/mcp@v0.0.22 fixes it.
