Cairn Remembers MCP Server

Local-first episodic memory for AI agents - and for you. A cairn is a stack of stones that marks a trail. This one marks the trail of your thinking: every decision, dead end, and reason becomes a node you - and any model - can find again, across sessions and across model generations.

People who work with agent memory, codex and knowledge graph and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package cairn-remembers - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.CairnRemembers is GitHub-verified and matches the repo owner
