Most AI agent frameworks implement memory by taking the last conversation turn, calculating an embedding, and storing it in a vector database.
When the agent queries this "memory", it runs a simple nearest-neighbor search. This breaks down in production:
Nexusyn is a dedicated data plane engine designed specifically for agentic long-term memory:
valid_from / valid_to). New statements supersede older ones automatically without deleting history.pgvector HNSW) + BM25 full-text search + entity graph expansion + recency & date-anchor boosts using Reciprocal Rank Fusion./v1/mcp) running over streamable HTTP. Connects directly to Claude Code, Cursor, Windsurf, or custom agent frameworks with zero glue code.Nexusyn is evaluated against standard public benchmarks for agent long-term memory under reproducible conditions:

Get the complete stack running locally (PostgreSQL 17+ with pgvector, the Nexusyn HTTP/MCP API on :8044, and the River background worker) in under 60 seconds:
# 1. Clone the repository
git clone https://github.com/nexusyn/engine.git
cd engine
# 2. Configure environment
cp .env.example .env
# Edit .env with your preferred model provider API keys
# (OpenAI, Anthropic, Gemini, Ollama, Jina, etc.)
# 3. Spin up the containers
docker compose up -d
# 4. Verify health

Nexusyn runs an HTTP Model Context Protocol (MCP) server at /v1/mcp. Any MCP-compliant client gets persistent long-term memory tools out of the box.
Connect Nexusyn to Claude Code with a single CLI command:
claude mcp add nexusyn --transport http \
"http://localhost:8044/v1/mcp" \
--header "Authorization: Bearer <YOUR_API_TOKEN>"
~/.cursor/mcp.json)Add Nexusyn to your Cursor global or project configuration:

"mcpServers": {
"nexusyn": {
"url": "http://localhost:8044/v1/mcp",
"headers": {
"Authorization": "Bearer <YOUR_API_TOKEN>"
