IsoKron audits and builds MCP servers. We test whether writes through an MCP server actually land, checked against the platform's own API. Public audits: the GitHub, Grafana, PostHog and Kubernetes MCP servers.
IsoKron is a one-person firm founded in 2026 by Joshua Bryan, after ten years as a support engineer at Ring. AI agents now write to real systems through MCP servers, and two agents writing at once can silently lose a change while both are told it worked. We test for that: real writes on a test tenant, overlapping and stale writes, checked against the platform's own API. We publish our audits and file fixes upstream.
