Disclosure: I’m the creator and maintainer of Klio. It’s free and open source — Apache 2.0 for the MCP shim and Claude Code plugin, AGPL-3.0 for the engine. There’s a Klio Cloud waitlist for teams (planned, not built yet) but everything described below works locally with no payment, no signup, and no email. What it is and who it’s for: Klio is a local memory daemon for anyone running two or more AI coding agents on the same machine — Claude Code plus Cursor plus Codex plus OpenCode plus OpenClaw plus Claude Desktop. It captures what one agent learns and makes it available to all the others, so you stop re-explaining your project, your preferences, and what you tried that didn’t work every single session. The pain that made me build it: Twelve “I prefer Bun, deploy to Railway, our codebase uses Effect” re-explanations to Claude Code in a row, then again when I switched to Cursor for a different task, then again to Codex. The agents don’t talk. So I made them talk. How it works: One install detects every supported AI agent on your machine and patches each one’s MCP config to point at the same shared bridge. They start sharing memory immediately: npx @klio-tech/klio init Local-only. Postgres + pgvector + Redis run in Docker on your laptop. AES-256-GCM encryption at rest. SHA-256 audit chain notarized hourly to OpenTimestamps. No telemetry, no phone home, no analytics. Seven MCP tools: recall , remember , observe , plan , decide , note , space . Distinct verbs because they measurably improve LLM tool selection over a generic write. Six Claude Code hooks for silent capture: SessionStart , UserPromptSubmit , PreToolUse , PostToolUse , SubagentStop , Stop . No “did you mean to remember this?” prompts. Memory captures itself. Six agents auto-detected and auto-configured: Claude Code, Claude Desktop (Chat + Cowork), Cursor, Codex, OpenCode, OpenClaw. Each adapter writes a timestamped backup of the MCP config it modifies — uninstall is byte-for-byte reversible: npx @klio-tech/klio uninstall Repo: https://github.com/klio-tech/klio Site: https://klio.tech/ submitted by /u/7hakurg
