Before you connect

Questions about Sliding Window Rate Limiter.

The practical details behind the request, access and result.

How does Sliding Window Rate Limiter prevent API errors?

It tracks every request in a moving timeframe, allowing your agent to see if a call will be blocked before it even happens.

Can I use Sliding Window Rate Limiter with Claude or Cursor?

Yes. Any MCP-compatible client like Claude, Cursor, or Windsurf can connect to this Connector to manage your API traffic.

Does the Sliding Window Rate Limiter help with multi-agent systems?

Absolutely. It is designed specifically to coordinate shared quotas across multiple agents so they don't overwhelm a single service.

How do I check my current API usage with this Connector?

You can simply ask your agent for a summary of your usage, and it will provide the current percentage of capacity used.

Will the Sliding Window Rate Limiter slow down my requests?

No. The check happens almost instantly, adding negligible latency to your existing workflow.

How does the sliding window differ from a fixed window?

A fixed window resets at specific clock intervals (e.g., every hour), which can allow bursts of traffic at the boundary. A sliding window uses a continuous timeframe, ensuring that the number of requests is always measured against the most recent duration.

Can I use `validate_request` to prevent API key exhaustion?

Yes. By tracking your request timestamps and using validate_request, you can proactively check if a new request will exceed your quota before actually making the call, saving both time and resources.

What is the purpose of `prune_history`?

prune_history removes timestamps that have moved past the sliding boundary into the expired zone, keeping your request history array small and efficient for subsequent calculations.

How does the sliding window approach differ from a fixed window?

Unlike fixed windows that reset at specific intervals, the sliding window tracks individual request timestamps. This prevents 'bursting' where double the allowed limit is processed right at the boundary of two windows.

Can I use this to manage OpenAI API limits?

Yes. By using evaluate_request with your provider's specific window and request limit, you can ensure your agents never trigger a 429 Too Many Requests error.

What does `get_window_density` tell me?

It provides a percentage of how much of your current window capacity is currently occupied by active requests, helping you monitor usage intensity.

How does this prevent 429 errors?

It uses check_rate_limit to determine if a request will exceed the quota. If the limit is reached, it provides the exact sleep_time_ms to wait, ensuring agents stay within the allowed window.

What is the difference between fixed and sliding windows?

Fixed windows reset at static time blocks, while sliding windows use a moving period relative to the current timestamp for smoother enforcement.

Can I monitor my current usage?

Yes, you can use get_usage_summary to see the usage percentage and status for each model under a specific provider.
