mindD v0.1.0
mindD is a self-hosted memory sidecar for agentic systems: one gRPC API
(with an HTTP/JSON mirror) over six memory blocks — kv, episodic, semantic,
artifact, lease and graph — with pluggable backends.
mindD is pre-1.0. Proto shapes under proto/mindd/*/v1 may still change
between minor versions. See CHANGELOG.md for the curated notes, including
known limitations.
