[gmeilus (Gustavo)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m not able to run the tools of playwright mcp server even if they are been tracked and seems to be available, when I try to use them it take a resource not found on this.

Steps to Reproduce

1. Install Playwright module on the project.
2. Configure the mcp server on Cursor:

"mcpServers": {
      "playwright-test": {
            "command": "npx",
            "args": [
            "playwright",
            "run-test-mcp-server"
      ],
    },
}

Expected Behavior

Be able to run the mcp tools on the chat.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Here is the error message even with the tools available it not works.

On earlier versions I was able to use it.

Hey, thanks for the report. There’s a similar open issue with MCP tools that show in Settings but aren’t available to the agent: MCP servers are not exposed to agents and Showing in Agent chat "No MCP resources available".

Need exact diagnostic data:

• Request ID right after the error (“…” menu in chat > Copy Request ID)
• Logs: Output Ctrl+Shift+U > “MCP Logs”
• Console: Help > Toggle Developer Tools > Console (errors when calling the tool)
• Terminal results:
• npx playwright run-test-mcp-server
• And for check: npx -y @playwright/mcp@latest --extension
• Which latest Cursor version worked with these tools for you?

Send the data - and I’ll escalate to engineers and link to the current ticket.

Hey, here’s the diagnostic info:

Terminal results:

npx playwright run-test-mcp-server - runs fine (no output, seems normal)

npx -y @playwright/mcp@latest --extension - completed successfully, no errors

Which latest Cursor version worked with these tools for you?
I’m not sure but was right before custom agents removal.

My setup:

• Node v24.2.0
• npm 11.3.0

Thanks for the detailed diagnostics! This matches a known issue we’re tracking. I’ll attach your data, including the Request ID.

+1 on this issue. I thought you guys were explicitly substituting the playwright mcp with the cursor IDE browser for a sec . All my other mcp servers are able to be discovered and used except for playwright.

I have the same issue with my custom MCP server build with dart mcp_server. Server and endpoints are visible in settings, MCP is “green” but I get “No MCP resources available” in Agent.

I’ve pinpointed that the last Cursor version without this issue is 2.0.77.

[gmeilus (Gustavo)]

What I had to do was rollback to Cursor 1.7, now I’m using it until the version 2 got a fix on this.
