🐘 The Philosophy

Legend says elephants remember watering holes across decades of shifting sands. Modern AI agents, on the other hand, forget your preferences the moment their context window slides shut.

Elephantine gives your agents permanent, unshakeable memory. Built from the ground up for standard commodity CPUs (2 vCPU / 4 GB RAM), Elephantine requires zero GPUs, makes zero external API calls, and enforces zero data leakage by storing everything directly on host disk via embedded LanceDB and SQLite.

⚡ Highlights

• 🏎 100% CPU-Native Execution: Sub-35ms recall latency on 2 vCPU servers powered by ONNX Runtime with AVX-512 SIMD thread pinning. No CUDA. No PyTorch bloat.
• 👥 Multi-Agent Shared Workspace: Seamless memory pooling (workspace_id) across teams (Coder, Tester, Architect) with Role-Based Authority Consensus (role_authority) preventing junior agents from overwriting senior architectural decisions.
• 📊 Built-in WebUI Inspector & Knowledge Graph: Real-time interactive dashboard (/dashboard) featuring memory ledgers and a Cytoscape.js interactive graph visualizer for entity relationships.
• 🦙 In-Process GGUF SLM Extraction: Local structured memory extraction via embedded llama-cpp-python (Qwen2.5-0.5B-Instruct), requiring zero background LLM servers.
• 🕸 Graph Memory & Knowledge Triplets: Native subject-predicate-object semantic graphs (/graph/query) integrated directly into the hybrid retrieval pipeline.
• ⚙️ Procedural Memory & Workflow Tracking: Records tool execution histories and learned multi-step procedural patterns (/procedural/track).
• 🔒 Local-First & Zero Leakage: Embedded LanceDB (Arrow/C++) vector store + SQLite WAL. Data never leaves your host filesystem.
• 🔌 Universal Agent Support (MCP & REST): Plugs directly into Google Antigravity, OpenAI Codex, Cursor Composer, GitHub Copilot, Windsurf, and Claude Desktop with 1-click automatic CLI installers.
• 🛡️ Enterprise RBAC & Security: Configurable RoleBasedAuthEngine with granular role permissions (admin, architect, editor, viewer) and API Key / Bearer token enforcement.

💻 Direct Terminal CLI Commands

Manage and inspect memories directly from your terminal without opening a browser or writing scripts:

# 1. Remember a fact with workspace and authority
elephantine remember "PostgreSQL 16 with pgvector extension is required" \
  --workspace phoenix-core \
  --category architecture \
  --authority 1.0

# 2. Recall memories via hybrid dense + BM25 search
elephantine recall "which database engine are we using?" \
  --workspace phoenix-core \
  --top-k 3

# 3. Register a proactive trigger (recurring or absolute)
elephantine trigger-create "Today is Friday! Weekly progress report is due at 17:00." \
  --trigger "weekly:FRI:17:00" \
  --workspace phoenix-core \
  --agent coder_agent

# 4. Pull pending unacknowledged proactive alerts
elephantine trigger-pending --agent coder_agent --workspace phoenix-core

---

🔔 Proactive Memory Triggers (Autonomous Memory Feeds)

Traditional memory systems (such as Mem0) are purely reactive: an AI agent must explicitly execute a query (/recall) to know what it remembered.

Elephantine introduces Proactive Memory Triggers: The engine actively stages alerts and feeds critical context to agents without requiring prompt lookups, based on:

• Recurring Schedules: weekly:FRI:17:00 (e.g. weekly reports), daily:09:00 (morning standups).
• Time Intervals: every:30m, every:2h, every:1d (cache invalidations, health checks).
• Exact Timestamps: ISO-8601 datetimes (2026-09-15T10:00:00Z).

Delivery Modes:

1. Pull-Based Check-in (Zero-Latency): Ajan seans başlattığında ya da döngü içinde bekleyen bildirimleri çeker:

   alerts = client.get_pending_alerts(target_agent="coder_agent", workspace_id="phoenix-core")
   for alert in alerts:
       print(f"Proactive context: {alert['content']}")
       client.acknowledge_alert(alert['trigger_id'])
   

2. Real-Time Streaming (SSE): Listen to live proactive triggers via GET /proactive/stream.
3. HTTP Webhooks: Configure webhook_url to receive instant asynchronous POST notifications.

👥 Multi-Agent Shared Workspace

Coordinate agent teams (e.g. Coder, Tester, Architect) with persistent memory pools and hierarchical authority protection:

from elephantine.client import ElephantineClient

# Connect to local Elephantine daemon
client = ElephantineClient("http://127.0.0.1:8765")

# 1. Lead Architect sets architectural baseline (Authority: 1.0)
client.remember(
    content="Database must strictly run PostgreSQL 16 with pgvector extension.",
    category="architecture",
    entity_key="project:db_engine",
    workspace_id="phoenix-core",
    role_authority=1.0
)

# 2. Junior Coder attempts to change database (Authority: 0.3)
# -> REJECTED by Role Authority Consensus (protected against lower authority)
client.remember(
    content="Let's switch project database to SQLite for simplicity.",
    category="architecture",
    entity_key="project:db_engine",
    workspace_id="phoenix-core",
    role_authority=0.3
)

# 3. Tester Agent recalls workspace memories (Authority-weighted re-ranking)
results = client.recall(
    query="Which database engine are we using?",
    workspace_id="phoenix-core"
)

# Output guarantees PostgreSQL 16 is preserved:
# [architecture] (Authority: 1.0) -> Database must strictly run PostgreSQL 16...

🖥️ WebUI Dashboard & Interactive Knowledge Graph

Elephantine includes a built-in, lightweight inspector accessible at http://localhost:8765/dashboard:

• Real-Time Memory Ledger: Inspect active vs deprecated memories, view revision counts and superseded states.
• 🕸 Interactive Knowledge Graph (Cytoscape.js): Explore semantic entities and subject-predicate-object triplets with force-directed (CoSE), circular, and concentric layouts.
• Click-to-Inspect: Tap any node or relationship edge to view confidence scores, source memories, and linked attributes.
• Authority & Conflict Tracking: Monitor role-based modifications and LWW (Last-Write-Wins) deprecation chains.

💻 SDKs & Integrations

1. Python SDK & LangChain Integration

import asyncio
from elephantine.client import AsyncElephantineClient, ElephantineLangChainMemory

async def main():
    async with AsyncElephantineClient("http://127.0.0.1:8765") as client:
        await client.remember(
            content="User prefers pytest with async test runners.",
            category="preference",
            entity_key="dev:test_runner",
            workspace_id="dev-team",
            role_authority=0.8
        )

        res = await client.recall(
            query="test runner preferences",
            workspace_id="dev-team",
            top_k=3
        )
        print("Recalled:", res)

    # LangChain Memory Adapter
    chain_memory = ElephantineLangChainMemory(
        base_url="http://127.0.0.1:8765",
        workspace_id="dev-team"
    )
    chain_memory.save_context({"input": "Hello"}, {"output": "I remember your preferences!"})

if __name__ == "__main__":
    asyncio.run(main())

2. TypeScript / Node.js SDK (@elephantine/sdk)

Available in sdks/typescript/:

import { ElephantineClient } from '@elephantine/sdk';

const client = new ElephantineClient('http://127.0.0.1:8765');

// Store memory
await client.remember({
  content: 'Production deployments occur on Tuesdays at 10:00 UTC.',
  category: 'devops',
  workspaceId: 'infra-team',
  roleAuthority: 0.9
});

// Recall memory
const res = await client.recall({
  query: 'deployment schedule',
  workspaceId: 'infra-team'
});
console.log(res.memories);

🛡️ Enterprise RBAC & Security

For multi-user teams and production deployments, Elephantine includes modular Role-Based Access Control:

• Predefined Roles:
  • admin: Full unrestricted access (read, write, delete, admin).
  • architect: Can read, write, and delete memories across all categories.
  • editor: Can read and write active memories.
  • viewer: Read-only recall access. Write and delete operations are rejected with HTTP 403 Forbidden.
• Token Authentication:
  • Enable with ELEPHANTINE_AUTH_ENABLED=true (or MEMAGENT_AUTH_ENABLED=true).
  • Authenticate requests via X-API-Key: <key> header or Authorization: Bearer <key>.
  • Default Community mode (AUTH_ENABLED=false) runs with zero configuration and zero friction.
