[BUG]: MCP error -32000: Connection closed for playwright #3902
Description
How are you running AnythingLLM?
Docker (local)
What happened?
Playwright MCP server fails to start (error -32000 “Connection closed”) even with explicit command path / PATH env
{
"mcpServers": {
"jdbc": {
"command": "/opt/homebrew/bin/jbang",
"args": [
"jdbc@quarkiverse/quarkus-mcp-servers",
"jdbc:postgresql://db.xxxxx.supabase.co:5432/postgres?user=xxxx&password=xxxxxx"
]
},
"playwright": {
"command": "/usr/local/bin/npx",
"args": ["-y", "@executeautomation/playwright-mcp-server"],
"env": {
"PATH": "/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin/npx"
}
}
}
}
What works
The JDBC MCP server starts and runs without issues.
• What doesn’t
Starting the Playwright MCP server always fails with the same error:
Failed to start MCP server: playwright [-32000] MCP error -32000: Connection closed
What I’ve tried
1. Keeping the env.PATH entry (as shown above).
2. Removing the env block entirely and relying only on the absolute path in command.
3. Verifying that /usr/local/bin/npx exists and runs npx -y @executeautomation/playwright-mcp-server correctly from the terminal.
In every case the JDBC server still works, but the Playwright server dies immediately with error -32000.
Are there known steps to reproduce?
