[Enhancement]: useInteractionHealthCheck should allow for no user interactions while an MCP server is running

[thonic]

What features would you like to see added?

When Librechat is configured to use a long running MCP server (with large timeouts, more than five minutes), the tool usage will timeout in the chat after five minutes and it will not complete, saying "fetch failed".

It would be nice to have this timeout as max(five minutes, MCP server timeouts) which would allow for long running MCP servers to be used. Because while the tool is running, no user interaction is likely to happen.

More details

This is now caused by the check in data-provider/connection.ts, by this function:

export const useInteractionHealthCheck = () => {
  const queryClient = useQueryClient();
  const lastInteractionTimeRef = useRef(Date.now());

  const checkHealthOnInteraction = useCallback(() => {
    const currentTime = Date.now();
    if (currentTime - lastInteractionTimeRef.current > Time.FIVE_MINUTES) {
      logger.log(
        'Checking health on interaction. Time elapsed:',
        currentTime - lastInteractionTimeRef.current,
      );
      queryClient.invalidateQueries([QueryKeys.health]);
      lastInteractionTimeRef.current = currentTime;
    }
  }, [queryClient]);

  return checkHealthOnInteraction;
};

As mentioned in the PR, this won't have a real effect on the MCP server timeouts. What does your MCP server config look like? Are you making use of timeout?

I've successfully tested MCP servers with 10+ minute-long processes, see my example MCP server:
