Self-hosted multimodal RAG memory service with LanceDB + RAG-Anything

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.

Please install and configure transcendence-memory-server for me:

1. Repository:
   https://github.com/leekkk2/transcendence-memory-server

2. Deployment target:
   • Service domain: <YOUR_DOMAIN>          # e.g. memory.example.com, or "localhost" for local-only
   • Reverse proxy: Nginx                    # remove this line if local-only
   • Backend listen: 127.0.0.1:8711
   • Public URL: https://<YOUR_DOMAIN>       # remove if local-only

3. Build flavor (pick one):
   • lite   — default, text memory + vector search + knowledge graph
   • full   — lite + multimodal (PDF/image/table parsing via RAG-Anything)

4. LLM / Embedding / Vision config:
   • LLM_BASE_URL=<YOUR_LLM_ENDPOINT>       # e.g. https://api.openai.com/v1
   • LLM_API_KEY=<YOUR_LLM_KEY>
   • LLM_MODEL=<YOUR_LLM_MODEL>             # e.g. gpt-4o, claude-sonnet-4-20250514, gemini-2.5-flash
   • EMBEDDING_BASE_URL=<YOUR_EMBED_ENDPOINT>
   • EMBEDDING_API_KEY=<YOUR_EMBED_KEY>
   • EMBEDDING_MODEL=<YOUR_EMBED_MODEL>      # e.g. text-embedding-3-small, gemini-embedding-001
   • VLM_API_KEY=<YOUR_VLM_KEY>              # optional, only needed for "full" build
   • VLM_MODEL=<YOUR_VLM_MODEL>              # e.g. gpt-4o, qwen3-vl-plus

5. Deployment requirements:
   • Build flavor: <lite or full>
   • Write .env correctly
   • Set RAG_ADVERTISED_ENDPOINT=https://<YOUR_DOMAIN>   # remove if local-only
   • Ensure service runs persistently
   • Nginx reverse proxy to 127.0.0.1:8711               # remove if local-only

6. Post-install verification:
   • Local health check:  http://127.0.0.1:8711/health
   • Public health check: https://<YOUR_DOMAIN>/health    # remove if local-only

7. After installation, output:
   • Actual deployment path
   • Actual listen port
   • Health check result
   • Connection string for the client skill
   • Default container name: <YOUR_CONTAINER>  # e.g. eva, my-agent

Execute install, configure, start, verify, and output the final usable result.
Do not omit the connection string.

Tip: Remove lines marked # remove if local-only when deploying on localhost without a domain. For the minimal setup (vector search only), you only need EMBEDDING_* keys — LLM_* and VLM_* are optional and unlock higher architecture tiers.

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
• Lite / Full Build Flavors — default lite image, optional full image for multimodal dependencies
• 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

Build Flavors

The server now exposes two build flavors:

Flavor	Default	Includes
lite	Yes	FastAPI, LanceDB, LightRAG, typed ingest, connection token export
full	No	lite + raganything multimodal dependencies

Switch flavors at build time:

# default
docker compose up -d --build

# full multimodal build
BUILD_TARGET=full docker compose up -d --build

/health reports the active build_flavor, whether the runtime is multimodal_capable, and any degraded_reasons.

Platform Support

• Python package — CI currently validates Linux and Windows on Python 3.11, 3.12, 3.13
• Docker images — published for linux/amd64 and linux/arm64
• macOS / Windows hosts — supported through Docker Desktop running Linux containers
• Native non-Linux containers — no native macOS container image exists, and no native Windows container image is published for this project

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)

Docker Desktop on macOS and Windows is supported as long as it is running Linux containers. Intel hosts will typically pull linux/amd64; Apple Silicon and Windows on Arm can pull linux/arm64.

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

Production (VPS + Nginx)

# Preflight check
bash scripts/preflight_check.sh

# optional: BUILD_TARGET=full
# 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.

/export-connection-token now returns three layers of onboarding material:

• token: backward-compatible base64 connection token for /tm connect <token>
• pairing_auth: explicit endpoint / api_key / container values for manual pairing
• agent_onboarding: exact prompts the AI should show the user before importing, plus the auth facts it should proactively disclose

For AI-assisted setup, do not silently import the token. Surface agent_onboarding.collect_from_user first, then tell the user which endpoint, container, and auth mode will be written into the local skill config.
