Prompt Compression Efficiency Calculator

Prompt Compression Efficiency Calculator MCP Connector for Claude

A+

Evaluate the performance, cost-effectiveness, and quality impact of prompt compression techniques.

3 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides deterministic tools to measure how effectively different prompt compression methods reduce token counts while maintaining semantic integrity. Use calculate_compression_metrics to derive the compression ratio, tokens saved, and cost savings. You can also use evaluate_technique_performance to verify if a specific method like summarization, pruning, or abstraction falls within expected domain benchmarks, or recommend_optimal_technique to identify the most efficient approach based on efficiency scores.

3 tools expose this connector's capabilities to your AI agent.

recommend_optimal_technique

Determines the most suitable compression technique based on efficiency scores

calculate_compression_metrics

Calculates the core mathematical performance metrics of a single compression attempt

evaluate_technique_performance

Compares a specific compression result against expected performance benchmarks

See how to talk to your AI agent using Prompt Compression Efficiency Calculator.

Calculate the metrics for a prompt that went from 1000 tokens to 200 tokens, with a quality score drop from 0.9 to 0.85, at a cost of 0.00002 per token.

The compression ratio is 5.0, tokens saved is 800, quality retention is 0.944, compression efficiency is 0.188, and cost savings is 0.016.

Is a summarization technique with a 7:1 ratio and 15% quality loss within the expected range?

Yes, a summarization technique with a 7:1 ratio and 15% quality loss is within the expected performance benchmarks.

Which technique is better: summarization with 0.5 efficiency or pruning with 0.8 efficiency?

The recommended technique is pruning.

You can use the `calculate_compression_metrics` tool. By providing the original token count, compressed token count, and the cost per token, the tool automatically calculates the `costSavings` for you.
