What does this MCP actually calculate?

It calculates chunk counts, overlap percentages, context utilization, and the mathematical limits of your context window.

Can I use this with Claude?

Yes, you can connect this MCP to any MCP-compatible client including Claude, Cursor, and Windsurf.

How does it help with RAG optimization?

It provides deterministic math to help you find the best balance between chunk size and overlap to maximize your context window usage.

Do I need to host this myself?

No, Vinkius hosts and manages the MCP for you. You just connect it to your client.

Is this for specific LLM models?

The math is universal, but you use it to find the specific limits of whatever context window your current model uses.

How do I know if my RAG configuration is unstable?

A configuration is flagged as unstable if the context utilization exceeds 90% or if the overlap overhead exceeds 30%.

What is the purpose of the optimal chunk size calculation?

The get_optimization_bounds capability calculates an optimal size that targets 70% context window utilization, providing a safety margin for system prompts and model responses.

Can I compare multiple chunking strategies at once?

Yes, you can use compare_chunk_strategies to pass an array of different chunk size and overlap combinations to see how they perform side-by-side.

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.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through RAG Chunk Optimization Calculator.

01
Compare chunk strategies
This capability compares how different chunking setups perform against each other. It lets you see the trade-offs between different sizes and overlaps in a single pass.
02
Calculate chunk metrics
This capability calculates the structural impact of your current parameters. It returns specific data like chunk counts and overlap overhead.
03
Get optimization bounds
This capability finds the mathematical limits of your context window. It tells you the maximum possible chunk sizes based on your specific constraints.

Real work

What teams actually run

Optimizing Token Usage

You use this to maximize context utilization so you aren't wasting tokens on unnecessary overhead.

Testing New Strategies

You can test a new chunk size against your current setup to see if it actually improves efficiency.

Preventing Context Overflow

You use the bounds capability to ensure your Top-K retrieval never exceeds the model's limit.

Benchmarking RAG Pipelines

You use the metrics capability to get a baseline of your current chunking performance.

One connector, every AI

RAG Chunk Optimization 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 RAG Chunk Optimization 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 RAG Chunk Optimization Calculator, so you can see the experience inside your AI.

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