sunsatosolutions/Vulcanus Generates a Git-versioned Markdown vault as project memory, then serves it over MCP. recall returns a project's capsule plus the read-next list and warns when the capsule is older than the decisions beneath it; search ranks by layer; writes are scoped — updatecapsule replaces one named section rather than rewriting the file. A doctor tool validates that every link resolves and every project is reachable, so the memory fails loudly instead of rotting. Plain Markdown, Obsidian-compatible, no database. npx @sunsato/vulcanus
LamantinAI/kaeru Memory for LLM agents: a local graph where the agent itself keeps decisions, tasks, hypotheses and reasoning between sessions, and gets a summary of what is open and overdue on every return to a project.

Works with Claude Code, Codex, Cursor, opencode and any MCP client.
yakuphanycl/instinct Self-learning memory for AI coding agents.
