Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN commenters link kcap posts about KurrentDB (formerly Event Store), its MCP Server, and its JavaScript projection engine, plus an experimental project for verifying AI-generated code. The comments give no view on the writing.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
kcap records Claude Code, Codex, Cursor, Gemini, and Copilot sessions as shared team memory. Continue lost work, switch agents, recall decisions, review PRs with the reasoning.

What Hacker News says?
Hi I am the creator of KurrentDB's MCP Server. KurrentDB (formerly known as Event Store) keeps data as a stream of events. This allows you to keep state transitions. We also have something called a projection engine which does a left fold on that stream using Javascript. This is unique to our database and this allows us to have a feedback loop back to the frontier model. You can use the MCP Server to generate a proj…

HN discussionI would like to Introduce to you an experimental project, built with Claude Code and meant to be used by coding agents first, to shorten the verification gap in AI generated code: To test it you need to go your coding agent and say "Use https://github.com/kurrent-io/poes/ to build and verify {prompt or spec} and then provide me with a proof-of-work (this is deterministic)" This is specially useful in long horizon ta…
