Features
NovaCortex is the privacy-first, self-hostable, MCP-native memory layer for AI agents. Your knowledge base never leaves your infrastructure, and a portable open format (PMF) means zero lock-in — the opposite of cloud-first tools like Mem0 and Zep. Apache-2.0 and free to self-host.
NovaCortex runs entirely on your own infrastructure with a single Docker deployment. Your knowledge base never leaves it — no third-party cloud, no data egress you did not approve. Retrieval even sends less data per query to the model provider than dumping raw context.
Export and import the entire graph as human-readable JSON, binary MessagePack (~60% smaller), or AES-256-GCM encrypted bundles. Every export ships with Merkle and content-hash integrity. Take your memory anywhere — zero lock-in.
Typed memories — episodic, semantic, procedural, and working — linked by a real relation graph. Edges like causes, contradicts, supersedes, and same_as model how knowledge actually connects, not just a flat pile of embeddings.
OpenAI-embedding vector search, or any OpenAI-compatible / local endpoint you point it at, with a transparent text fallback when embeddings are unavailable. Add optional recency weighting and rely on strict namespace isolation between projects.
A native MCP server exposes 15 tools to Claude, Cursor, and any MCP client. Prefer code? Reach for the REST API (with Swagger), TypeScript and Python SDKs, or the CLI. Wire NovaCortex into whatever stack you already run.
Retrieval keeps prompts lean — up to 98.8% fewer input tokens than dumping the whole knowledge base into context, and 80.0% on LongMemEval_S at ~5% of the full-context token bill. It is the proof, not the pitch: smaller prompts mean lower cost and sharper answers.
See the benchmark →Opt-in OpenTelemetry traces, scope-gated API tokens, an audit log, and webhooks for everything that matters. Background processing handles decay, consolidation, and relation discovery so the graph stays healthy on its own.
Self-host in minutes with Docker. Apache-2.0, no cloud account, and your data stays yours — portable, encrypted, and free.
