# Graphiti MCP Server
Fork of the [getzep/graphiti](https://github.com/getzep/graphiti) example with a focus on developer experience and multi‑project support. Graphiti extracts entities and relationships from text and stores them in Neo4j. This repo adds a CLI that spins up a root server plus project‑specific MCP servers in Docker so several knowledge graphs share the same database.
## Quick Start
1. **Install and clone**
```bash
pipx install 'git+https://github.com/rawr-ai/mcp-graphiti.git'
git clone https://github.com/rawr-ai/mcp-graphiti.git
cd mcp-graphiti
cp .env.example .env # fill in Neo4j credentials and your OpenAI key
```
2. **Launch services**
```bash
graphiti compose # generates docker-compose.yml and updates .cursor/mcp.json
graphiti up -d
```
The root server runs on port **8000**; project containers start at **8001**.
3. **Create a project**
```bash
cd /path/to/my-kg
graphiti init my-kg # writes ai/graph/mcp-config.yaml
# add entity definitions under ai/graph/entities/
```
Rerun `graphiti compose && graphiti up -d` from anywhere to start its container.
Once running you can:
- Check `http://localhost:8000/graphiti/status`.
- Connect MCP‑compatible tools to `http://localhost:800{N}/sse`.
- Browse Neo4j at `http://localhost:7474` using the credentials in `.env`.
### Security note
If `NEO4J_PASSWORD` remains `password` the server refuses to start unless `GRAPHITI_ENV=dev`. Always use a strong password in production.
## Why this fork?
The upstream repository assumes one server per compose file. Here a single compose file manages many project servers that share Neo4j. Each service gets its own `group_id`, entities and model so projects stay isolated while running on the same database.
### Highlights
- **Project isolation** – different extraction rules or models never collide.
- **Editor auto‑discovery** – ports are written to `.cursor/mcp.json`.
- **Crash containment** – a bad prompt only restarts its container.
- **Hot reload** – tweak a project's config and run `graphiti reload <container>`.
Leave `mcp-projects.yaml` empty if you only need the root server.
## Danger zone
Setting `NEO4J_DESTROY_ENTIRE_GRAPH=true` wipes *all* projects the next time you run `graphiti up`. Use with care.
