Jarroba Tools MCP

A family of local MCP servers providing deterministic AI tools including CI log analysis, test audits, SQL queries on ephemeral PostgreSQL, Kubernetes manifest validation, Cedar policy checking, regex ReDoS detection, diagrams, and unit-aware mathematics. These tools run locally on the user's machine without uploading data, reusing the engines from jarroba.com/tools.
