Answer-rate optimisation for a call center

AI Value Loop

~1M calls/day · MCP tools for Claude

Rust (Axum), DuckDB/DuckLake, PostgreSQL, Valkey, Meilisearch and a Svelte dashboard on Oracle Cloud. Ingests ~1M calls/day in 5-minute batches and detects answer-rate drops by route and server. An MCP server with 13 Rust tools (fixed SQL, statistics in code: Wilson intervals, MSTL baselines, switchback tests) lets Claude propose and critique hypotheses while a human approves. Privacy-first: a local model triages alerts and the LLM only sees aggregates.
