What can this MCP do?

It provides mathematical modeling for LLM context window management, allowing you to calculate token reduction and quality trade-offs.

Which AI clients can use this MCP?

You can use this with any MCP-compatible client like Claude, Cursor, Windsurf, or VS Code.

How does it handle multiple compression steps?

You can use the simulate_cascading_compression capability to model the outcome of applying multiple reduction stages in a specific sequence.

Can I compare different reduction methods?

Yes, the evaluate_technique_efficiency capability lets you compare how different techniques perform against your specific constraints.

Does it help with hitting specific token counts?

Yes, the calculate_compression_strategy capability determines the most efficient way to reach a specific target token count.

How do I find the best way to reduce my context size?

You can use the calculate_compression_strategy capability. Provide your original token count, your target token count, and the techniques you want to allow, and it will return the optimal mix to minimize quality loss.

Can I model multiple compression steps in a row?

Yes, use simulate_cascading_compression to model how applying techniques sequentially (like deduplication followed by summarization) affects the final token count and cumulative quality loss.

What happens if the compression ratio is too high?

If the compression ratio exceeds 50 or the quality loss exceeds 0.3, the system will trigger a warning in the results to alert you to the high risk of information loss.

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 Context Window Compression Calculator.

01
Evaluate technique efficiency
This capability compares how different compression methods perform against your specific target constraints. It helps you see which technique hits the sweet spot for your data.
02
Simulate cascading compression
This capability models the results of applying multiple compression stages in a specific order. Use it to see how sequential reduction steps affect the final output.
03
Calculate compression strategy
This capability finds the most efficient way to reach a specific token target. It picks the best mix of techniques to hit your number.

Real work

What teams actually run

Cost Optimization

Reduce token usage in long-running agent sessions to lower API costs.

Context Management

Fit massive datasets into limited context windows by finding the best pruning mix.

Workflow Testing

Simulate how a sequence of deduplication and summarization affects a specific document.

Constraint Validation

Verify if a specific compression ratio is achievable with your current techniques.

One connector, every AI

Context Window Compression 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 Context Window Compression 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.
