What kind of rate limiting algorithms does this MCP handle?

It handles industry-standard algorithms, including the Token Bucket and Leaky Bucket models. This lets you simulate how your traffic will behave under different quota rules.

Can I use this to plan for future usage?

Yes. You can use the function to project remaining capacity, giving you a clear forecast of how many requests you have left before hitting zero.

Is this useful for batch jobs?

Absolutely. By using the window reset predictor, you can schedule large batch jobs to run immediately after a quota window resets, maximizing efficiency.

Does this MCP require authentication?

No, this MCP does not require authentication to run its calculations. You can use it immediately for planning and simulation.

How can I predict when my API quota will run out?

Use the project_remaining_capacity capability by providing your total limit, current usage, and window duration.

Can I simulate a burst of traffic?

Yes, the simulate_token_mechanics capability allows you to check if a specific burst size is permissible given your current bucket capacity and refill rate.

How do I avoid 429 errors?

You can use calculate_request_interval to find the minimum delay required between requests to stay within your allowed rate.

Connect API Rate Limit Calculator to ChatGPT and Claude

Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Stop hitting rate limits before they happen.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 4 capabilities

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through API Rate Limit Calculator.

01
Estimate next reset
Predict this capability to find the exact time a fixed or sliding usage window boundary will occur.
02
Simulate token mechanics
Use this capability to simulate the current state of common traffic-shaping models, like the Token Bucket or Leaky Bucket.
03
Project remaining capacity
This function forecasts how many more requests your account can handle before the current quota is fully exhausted.
04
Calculate request interval
Determine the minimum time gap required between API calls to stay under your usage limit.

Real work

What teams actually run

Implementing a New Feature

Before launching a feature that calls a third-party API, use this MCP to predict if your current quota can support the expected traffic volume.

Batch Data Processing

When running a nightly job that makes thousands of calls, use the window reset predictor to schedule the job for the optimal time.

High-Traffic Event Handling

If your service anticipates a sudden spike in users (like a sale), simulate the traffic burst to ensure your API calls won't fail.

Optimizing API Calls

Use the interval calculator to determine the minimum safe delay between calls, maximizing throughput without violating limits.

One connector, every AI

API Rate Limit Calculator works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put API Rate Limit Calculator to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of API Rate Limit Calculator, so you can see the experience inside your AI.

It does not authenticate your account with API Rate Limit Calculator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
