What algorithms does this MCP support?

This MCP supports Token Bucket, Leaky Bucket, and sliding window rate limiting.

How does it help prevent API rate limiting errors?

It allows your agent to calculate if a request will be permitted before it is actually sent, preventing 429 errors.

Can I use this with any AI client?

Yes, it works with any MCP-compatible client including Claude, Cursor, and Windsurf.

Does this MCP host the logic?

Yes, Vinkius hosts the MCP, so you don't need to run the math engine on your own local machine.

Can it manage multiple agents at once?

Yes, it includes capabilities to calculate distributed metrics and manage global limits across multiple agents.

How does the Token Bucket model work?

The calculate_token_bucket_state capability calculates available tokens by adding the refill rate multiplied by elapsed time to the current token count, capped by the burst capacity.

Can I check for queue overflow?

Yes, use calculate_leaky_bucket_state to determine the current queue depth and the number of requests that resulted in an overflow.

How are global limits shared among multiple agents?

The calculate_distributed_and_window_metrics capability calculates the per-agent share by dividing the total limit by the number of active agents.

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 · 3 capabilities

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Rate Limiter State Calculator.

01
Calculate distributed and window metrics
This capability provides high-level oversight of global limits and how dense your requests are over time.
02
Calculate leaky bucket state
Use this to check the current congestion and overflow status of a Leaky Bucket algorithm.
03
Calculate token bucket state
This capability determines if a request can be fulfilled using the Token Bucket algorithm and calculates the necessary wait time if it cannot.

Real work

What teams actually run

API Quota Management

An agent checks token availability before calling a third-party API to avoid being blocked.

Traffic Shaping

Use Leaky Bucket math to smooth out bursts of requests from an autonomous agent.

Multi-Agent Coordination

Distribute a global request limit across several different agents to ensure no single one hogs the capacity.

Congestion Control

Monitor queue depth to decide when to drop requests rather than letting them overflow.

One connector, every AI

Rate Limiter State 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 Rate Limiter State 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 Rate Limiter State Calculator, so you can see the experience inside your AI.

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