Why people use Context Window Optimizer
Stop token overflow with Context Window Optimizer
This MCP changes that. Instead of brute-forcing your way through token limits, you let the agent intelligently curate its own memory. You get a streamlined, high-density prompt that hits the sweet spot of relevance and brevity. It turns a messy pile of data into a sharp, focused instruction set.
What Vinkius changes
That your agent gets exactly the information it needs to act, without the bloat.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect
Questions about Context Window Optimizer.
The practical details behind the request, access and result.
How does Context Window Optimizer help with token costs?
It reduces the number of tokens you send to your AI client by filtering out irrelevant data. Fewer tokens mean lower costs for every request your agent makes.
Can I use Context Window Optimizer with Claude or Cursor?
Yes. Since it follows the standard protocol, you can connect it to any compatible client like Claude, Cursor, or Windsurf through Vinkius.
Will this make my AI agent smarter?
It makes your agent more focused. By removing noise and keeping only relevant, recent information, the agent is less likely to get confused or hallucinate.
Does Context Window Optimizer replace RAG?
Not exactly. RAG finds the data, while this MCP optimizes the specific pieces of data you've already found to ensure they fit perfectly into the prompt.
How does it decide what information is important?
It uses a mathematical approach that looks at how relevant a piece of information is to your goal and how recently it happened, ensuring the most useful data stays in the window.
How does the selection process work?
The process uses select_optimal_context to sort items by relevance score and recency, then greedily adds them until the token limit is reached.
Can I reserve specific messages?
Yes, you can use the reservation rules in select_optimal_context to ensure the system prompt and the last user message are always included.
How do I measure if my context is efficient?
You can use the evaluate_context_efficiency capability to get a report on utilization ratio, density score, and coverage gap.
What is the optimization score?
The optimization score is a metric returned by the selection capability that represents the aggregate relevance of the items successfully selected within your budget.
