Hi Bright Data team,

We're using the Bright Data MCP in an agent-based workflow (via n8n).
Under moderate load (~100 MCP calls per workflow run), we occasionally receive:

502 Bad Gateway responses (HTML error page from gateway)

The error is rare per-call, but statistically guaranteed at scale.
There is currently no documented retry / backoff guidance specific to MCP usage.

Questions:

1. Are intermittent 502s expected from the MCP gateway?
2. Do MCP endpoints support Retry-After headers?
3. Is there an official recommended retry + backoff policy for MCP?
4. Are there known concurrency or rate limits specific to MCP usage?

This is not a routing issue on our side -- MCP dynamically selects endpoints/params as designed.

Thanks in advance -- guidance here would help make MCP reliable at scale.
