How do I calculate my cache hit rate?

You can use the `analyze_cache_performance` tool. It processes your request logs and returns the exact `cacheHits` and `cacheHitRate` based on your provided TTL and cache size.

What is the purpose of the warmup metrics?

The `calculate_warmup_metrics` tool measures the time elapsed from the first request until the cache reaches its defined token capacity.

Can this tool help optimize my cache settings?

Yes, the `validate_cache_configuration` tool compares your current settings against request patterns to suggest an optimal TTL and cache size.

More Details Connect to Claude

This MCP server provides deterministic diagnostic tools to analyze the effectiveness of LLM prompt prefix caching. Use analyze_cache_performance to calculate hit rates, tokens saved, and cache efficiency. You can also use calculate_warmup_metrics to determine how long it takes to reach cache saturation, or validate_cache_configuration to check if your current TTL and cache size settings are optimal for your request patterns.
