2026-03-19T17:21:55.946Z [Bright Data] [info] Client transport closed { metadata: undefined }
2026-03-19T17:21:55.946Z [Bright Data] [info] Server transport closed unexpectedly, this is likely due to the process exiting early. If you are developing this MCP server you can add output to stderr (i.e. `console.error('...')` in JavaScript, `print('...', file=sys.stderr)` in python) and it will appear in this log. { metadata: undefined }
2026-03-19T17:21:55.946Z [Bright Data] [error] Server disconnected. For troubleshooting guidance, please visit our [debugging documentation](https://modelcontextprotocol.io/docs/tools/debugging) { metadata: { context: 'connection', stack: undefined } }
