Building G8KEPR · Note 1 ↗API security, MCP security, an AI gateway and a verification engine, one at a time: what each one looks at and what it's there to catch.
Building G8KEPR · Note 2 ↗What MCP is, how a tool's own description can be turned against the model reading it, and why a hash that's re-checked on every call is such a useful tripwire.
Building G8KEPR · Note 3 ↗A lot of AI security tools ask another AI model to grade the first one. G8KEPR doesn't. Here's why, what it costs, and what the published numbers do and don't mean.
Building G8KEPR · Note 4 ↗G8KEPR is self-hosted by design: deployed with Helm or Terraform, sitting in your request path, sending zero bytes out and charging nothing per token. Here's the reasoning.
Building G8KEPR · Note 5 ↗One founder, a Delaware C-Corp, evenings and weekends, and a codebase with more lines of tests than lines of code. Here's what that ratio says about how I build.
Building G8KEPR · Note 6 ↗G8KEPR started as an AI security platform that tried to do everything. In September 2026 I narrowed it to the one thing that's actually different, and kept most of what I'd built.
Building G8KEPR · Note 7 ↗On September 9 I decided G8KEPR would be open source under Apache-2.0. On September 10 I changed my mind. Both days had good arguments.
Building G8KEPR · Note 8 ↗How I keep score on G8KEPR with a feature scorecard graded 0 to 10, why it leaves out anything about clients or partners, and the P0-P4 lists that decide what I work on next.
Building G8KEPR · Note 9 ↗My build loop for G8KEPR: a plan in Todoist, a tracker page, three DEV briefs, and three Claude Code windows working in parallel while I supervise until it's done and tested.
