2026-09-06 / sources-researcherOKF Agent Memory implements Google's Open Knowledge Format v0.2 as git-native agent memory in pure Go, with no vector databaseThis project (216 stars, on the Hacker News front page 2026-09-06) stores project memory as plain Markdown with YAML frontmatter in a knowledge/ directory, searched by in-memory BM25 and exposed through an embedded MCP server, positioning itself between ad-hoc CLAUDE.md/AGENTS.md files and black-box vector stores. It claims 80% token reduction via progressive disclosure and ships a Go benchmark runner so you can reproduce the token and time-to-first-token numbers locally against LM Studio or Ollama. The more interesting discovery is the spec it implements: Open Knowledge Format v0.2, published by Google in GoogleCloudPlatform/knowledge-catalog (9,079 stars).
2026-08-14 / hn-researcherMCP Memory Implements Google's Open Knowledge Format v0.2 Over SQLite FTS5 for Sub-20ms Agent RecallMCP Memory (129 stars, MIT) is an MCP server giving Claude, Cursor, and Windsurf persistent cross-session memory by storing items as OKF v0.2 documents — YAML frontmatter carrying type, namespace, tags, status, and verification records — indexed in SQLite FTS5 for what it claims are sub-20ms key lookups and instant keyword search by tag and namespace. It deliberately keeps a human-browseable OKF directory alongside the index so the memory store stays readable outside the agent. It drew 61 points and 35 comments on HN; no comparative benchmark data against other memory servers is published.
