eigent/server

Purpose

server/ provides a local backend (FastAPI + PostgreSQL) to achieve complete separation between local and cloud environments. After deploying this service, sensitive data such as user registration, model provider configurations, tool settings, and chat history are stored on your machine and are not uploaded to our cloud unless you explicitly configure external services (e.g., cloud model providers or remote MCP servers).

Services Provided (Main Modules)

• Users & Accounts
  • POST /register: Email + password registration (local DB only)
  • POST /login: Email + password login; returns a locally issued token
  • GET/PUT /user, /user/profile, /user/privacy, /user/current_credits, /user/stat, etc.
• Model Providers (store local/cloud model access configurations)
  • GET /providers, POST /provider, PUT /provider/{id}, DELETE /provider/{id}
  • POST /provider/prefer: Set a preferred provider (frontend/backend will prioritize it)
• Config Center (store secrets/params required by tools/capabilities)
  • GET /configs, POST /configs, PUT /configs/{id}, DELETE /configs/{id}, GET /config/info
• Chat & Data
  • History, snapshots, sharing, etc. in app/controller/chat/, all persisted to local DB
• MCP Management (import local/remote MCP servers)
  • GET /mcps, POST /mcp/install, POST /mcp/import/{Local|Remote}, etc.

Note: All the above data is stored in the local PostgreSQL volume in Docker (see “Data Persistence” below). If you configure external models or remote MCP, requests go to the third-party services you specify.

Quick Start (Docker)

Prerequisites

• Docker Desktop: Installed and running
• Python: 3.10.* (3.10.15 recommended)
• Node.js: >=18.0.0 <23.0.0

Setup Steps

1. Start services

cd server
# Copy .env.example to .env(or create .env according to .env.example)
cp .env.example .env
docker compose up -d

2. Start Frontend (Local Mode)

• In the project root directory, create or modify .env.development to enable local mode and point to the local backend:

VITE_BASE_URL=/api
VITE_USE_LOCAL_PROXY=true
VITE_PROXY_URL=http://localhost:3001

• Start the frontend application:

npm install
npm run dev

Open API docs

• http://localhost:3001/docs (Swagger UI)

Ports

• API: Host 3001 → Container 5678
• PostgreSQL: Host 5432 → Container 5432

Data Persistence

• DB data is stored in Docker volume server_postgres_data at /var/lib/postgresql/data inside the container
• Database migrations run automatically on container startup (see start.sh → alembic upgrade head)

Common Commands

# List running containers
docker ps

# Stop/Start API container (keep DB)
docker stop eigent_api
docker start eigent_api

# Stop/Start all (API + DB)
docker compose stop
docker compose start

# View logs
docker logs -f eigent_api | cat
docker logs -f eigent_postgres | cat

---

Developer Mode (Optional)

You can run the API locally with hot-reload while keeping the database in Docker:

# Stop API in container, keep DB
docker stop eigent_api

# Initialize database (first-time or when DB schema changes)
cd server
uv run alembic upgrade head

# Run locally (provide DB connection string)
export database_url=postgresql://postgres:123456@localhost:5432/eigent
uv run uvicorn main:api --reload --port 3001 --host 0.0.0.0

---

Others

• API docs: http://localhost:3001/docs
• Runtime logs: /app/runtime/log/app.log in the container
• i18n (for developers)

uv run pybabel extract -F babel.cfg -o messages.pot .
uv run pybabel init -i messages.pot -d lang -l zh_CN
uv run pybabel compile -d lang -l zh_CN

For a fully offline environment, only use local models and local MCP servers, and avoid configuring any external Providers or remote MCP addresses.
