Koskamo

Jarroba Tools MCP

A family of local MCP servers providing deterministic tools for AI agents that run on the user's machine without uploading data. It includes servers for CI logs, test audits, SQL on ephemeral PostgreSQL, Kubernetes manifests, Cedar policies, regex ReDoS analysis, diagrams, and maths with units, reusing engines from jarroba.com/tools.
