Hey Product Hunt!Hey Product Hunt! 👋 I'm one of the makers of Markbase — shared memory for your AI agents. A hosted Markdown MCP server that gives a whole fleet of agents one persistent place to read and write. The itch: agentic work isn't one model anymore. It's Claude Code on the engineering, Claude.ai on the thinking, other harnesses for the rest — and they all need to share state so the next one picks up where the last left off. A local notes/ folder breaks the second a second agent shows up. Notion's built for humans, not an API. So we built the thing shaped for a fleet. What you get: 📝 Just Markdown — plain .md files in versioned storage, no lock-in, export anytime. 🔒 Conflict-free — every write asserts an ETag, so two agents racing the same file can't clobber each other. 🧩 Typed collections — drop a _schema.md and records become queryable rows, still Markdown underneath. The fun part: we run Markbase on Markbase — our own PRD, architecture, and ~50 decision records live in it, written by the agents that build it. Invite-only private preview for now. I'll be in the comments all day — would love to hear how you're handling agent memory today. AMA! 🙏
