Transcendence Memory Server

Self-hosted multimodal RAG cloud memory service — a shared brain for your AI agents.

中文文档

Transcendence Memory Server is a cloud memory backend that multiple AI agents connect to simultaneously. Each agent stores its own memories in isolated containers, while being able to cross-query other agents' knowledge — turning isolated AI sessions into a collaborative, persistent knowledge network.

Why Cloud Memory?

Problem	Without	With Transcendence
Session ends	Memory lost	Persisted to cloud, recoverable anytime
Switch agents	Start from zero	New agent inherits context via search
Cross-project	Knowledge siloed	Agent B queries Agent A's decisions
Team of agents	Each works in isolation	Shared container for collective knowledge
Onboarding	Re-explain everything	Agent reads past decisions and rationale

Features

• Multi-Agent Cloud Memory — one server, many agents; each stores its own, each can query others
• Container Isolation — per-agent or per-project namespaces with full CRUD; shared containers for team knowledge
• LanceDB Vector Search — sub-second semantic retrieval over task cards, memory objects, and structured data
• LightRAG Knowledge Graph — entity/relation extraction with hybrid retrieval (local + global + keyword)
• RAG-Anything Multimodal — PDF, image, and table parsing with vision model support
• Auto-Detect Architecture — automatically enables capabilities based on configured API keys
• Connection Token — one-step client setup; give each agent a token and it's connected
• Zero Permission Issues — Docker named volumes, no bind mount headaches

Architecture Tiers

The server auto-detects its capability tier based on your .env configuration:

Tier	Required Keys	Capabilities
lancedb-only	EMBEDDING_API_KEY	Vector search, typed objects, structured ingest
lancedb+lightrag	+ LLM_API_KEY	+ Knowledge graph, entity extraction, hybrid queries
rag-everything	+ VLM_API_KEY	+ PDF/image/table parsing, vision model queries

Quick Start

Docker (recommended)

git clone https://github.com/leekkk2/transcendence-memory-server.git
cd transcendence-memory-server
cp .env.example .env    # edit with your API keys
docker compose up -d --build
curl http://localhost:8711/health

Production (VPS + Nginx)

# Preflight check
bash scripts/preflight_check.sh

# Deploy with localhost-only binding
docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --build

Connect Your Agents

Once the server is running, each agent gets its own connection token:

# Export a token for Agent A
curl -sS "http://localhost:8711/export-connection-token?container=agent-a" \
  -H "X-API-KEY: your-key"

# Export a token for Agent B (different container)
curl -sS "http://localhost:8711/export-connection-token?container=agent-b" \
  -H "X-API-KEY: your-key"

# Export a shared container token (for cross-agent collaboration)
curl -sS "http://localhost:8711/export-connection-token?container=shared" \
  -H "X-API-KEY: your-key"

Give each token to the corresponding agent. With the transcendence-memory skill installed, the agent runs /tm connect <token> and it's ready.

Local Development

./scripts/bootstrap_dev.sh
export RAG_API_KEY="your-key"
export EMBEDDING_API_KEY="your-key"
./scripts/run_task_rag_server.sh

API Overview

CLI

pip install -e .
tm-server start              # Start server (default 0.0.0.0:8711)
tm-server start --port 9000  # Custom port
tm-server health             # Health check
tm-server export-token       # Export connection token

Client Skill
