Koskamo

PQS MCP Server

An MCP server that scores LLM prompts across 8 quality dimensions (clarity, specificity, context, etc.) before inference. It provides grades, percentiles, and dimension breakdowns. The free tier offers basic scoring, while the Pro subscription enables prompt optimization and side-by-side model comparisons.
