What is Agentic Memory?

Agentic Memory gives AI agents persistent, cross-session, local-first memory — no cloud, no vendor lock-in, no API keys required. Memories are stored as human-readable Markdown files. A derived SQLite index enables fast full-text, semantic, and knowledge-graph search.

Built for Claude Code, OpenCode, the Agentic Memory IDE, and any MCP-compatible agent harness.

Quick Start

from agentic_memory import MemoryClient

mc = MemoryClient()
mc.save("User prefers dark mode", category="preferences")
results = mc.search("dark mode")
for r in results:
    print(f"[{r.score:.2f}] {r.content}")

Agent Scoping

from agentic_memory import AgentMemory

coder = AgentMemory(agent_id="coder")
coder.save("Frontend uses React with TypeScript")

designer = AgentMemory(agent_id="designer")
designer.save("Brand colors are #FF5733 and #33FF57")

MCP Server

# Add to your MCP config
{
  "agentic-memory": {
    "command": "agentic-memory-server"
  }
}

REST API

agentic-memory api --port 9878
curl http://localhost:9878/api/v1/search?q=dark+mode

Features

Search — 14-Phase Hybrid Pipeline

Phase

Technique

Purpose

1

Query parsing + expansion

Normalization, reasoning expansion

2

Skill-first lookup

Conditional early return on skill match

3

Cache check

Return cached results if fresh

4

DB setup + filter construction

Open connection, build filters

5

FTS5 BM25 + KG facts

Keyword + fact retrieval

6

Embedding fallback

Semantic vector search (usearch + model2vec)

7

Hybrid fusion (RRF)

Merge sparse + dense results

8

Temporal filtering

Decay old memories, exclude outdated

9

Chunk enhancement + session clustering

Enrich with sub-document chunks

10

KG boost + multi-hop traversal

Concept centrality, graph expansion

11

Reranking

Cross-encoder + ColBERT late-interaction

12

Build output items

Assemble result objects

13

Postprocessing

Safety gates, quality filters, profiling

14

Finalization

Access recording, telemetry, envelope

Each phase is independently isolated — no single failure kills the search.

Write — Crash-Safe, Conflict-Preserving

  • Saga transactions — Crash-consistent writes with undo/redo

  • CQRS write journal — Lock-free multi-agent writes via journal.db

  • CRDT field-level LWWES — Concurrent edits to different fields both win

  • Safe atomic write — POSIX rename, conflict file preservation

Knowledge Graph — Temporal + Contradiction-Aware

  • Entity extraction with Jaccard fuzzy matching

  • Temporal edges with valid_at / invalid_at

  • Contradiction detection and supersession chains

  • Graph analytics (centrality, community detection)

Neural Forget Curve

Surprise-based retention formula considering access patterns, query relevance, recency, and importance:

retention = sigmoid(w_acc × access + w_surp × surprise + w_imp × importance + w_fit × fitness - w_rec × recency - bias)

Cron Consolidation

39 crontab entries replaced with 1 consolidated scheduler that runs every 5 minutes, checks which jobs are due by frequency tier, and runs them sequentially.

System Health Dashboard

memory_system_health MCP tool returns green/yellow/red across 6 dimensions with actionable next steps: database, search, worker, crons, auto-save, disk.
