Setup

1. Install dependencies:

   pip install -r requirements.txt
   

2. Configure environment:

   cp env.local .env
   # Edit .env to add your Langfuse credentials if needed
   

3. Ensure Claude CLI is installed and configured:

   claude --version
   

Running the Server

Using Docker Compose (Recommended):

# Start all services (FastAPI on 8334, Claude-Mem Manager on 37777, File API on 38888)
docker-compose up -d

# View logs
docker-compose logs -f

# Stop services
docker-compose down

The FastAPI server will be available at http://localhost:8334
The Claude-Mem Manager UI will be available at http://localhost:37777/switch_user
All other traffic on port 37777 will be proxied to the active claude-mem worker
The File API service will be available at http://localhost:38888 The CLI wheel server will be available at http://localhost:11113

Using Python directly:

python -m app.main

Using Uvicorn:

uvicorn app.main:app --reload --host 0.0.0.0 --port 8334

The server will start at http://localhost:8334

CLI Auto Upgrade

Install from PyPI:

python -m pip install --upgrade pip
python -m pip install --upgrade luckee-cli

If you want to validate a dev publish first, install from TestPyPI:

python -m pip install --upgrade \
  --index-url https://test.pypi.org/simple/ \
  --extra-index-url https://pypi.org/simple \
  luckee-cli

Upgrade the installed CLI:

luckee --upgrade

Or while inside interactive CLI:

/upgrade

API Endpoints

Root

• GET / - API information and available endpoints

Health Check

• GET /health - Health check endpoint

Agent Test

• GET /api/agent/test - Test the agent router

Agent Stream (SSE)

• POST /api/agent/stream - Stream agent responses via Server-Sent Events

Request Body:

{
  "query": "add a keyword test_keyword_1",
  "thread_id": null,
  "user_id": "dylan",
  "working_dir": null,
  "system_prompt": null
}

Response: Server-Sent Events stream with structured state messages.

File API (Port 38888)

• GET /api/v2/resume_thread - Resume a thread by streaming messages (SSE)
• GET /api/v2/list_threads - List all thread IDs for a user
• GET /api/v2/fetch_files - Fetch files from user directories

Resume Thread (SSE) Query Parameters:

• thread_id: Thread ID (must be a valid UUID)
• user_id: User ID

Resume Thread Example:

curl -N "http://localhost:38888/api/v2/resume_thread?thread_id=550e8400-e29b-41d4-a716-446655440000&user_id=dylan"

The stream always starts with a config message containing metadata from working_dir/metadata.json, followed by all messages from streaming_messages.jsonl, and ends with a completion event.

List Threads Query Parameters:

• user_id: User ID

List Threads Example:

curl "http://localhost:38888/api/v2/list_threads?user_id=dylan"

Fetch Files Query Parameters:

• type: Type of file to fetch (csv, json, or json_folder)
• thread_id: Thread ID (must be a valid UUID string)
• path: Relative path to the file from working_dir
• user_id: User ID

Examples:

Fetch a JSON file:

curl "http://localhost:38888/api/v2/fetch_files?type=json&thread_id=550e8400-e29b-41d4-a716-446655440000&path=data/config.json&user_id=dylan"

Fetch a CSV file:

curl "http://localhost:38888/api/v2/fetch_files?type=csv&thread_id=550e8400-e29b-41d4-a716-446655440000&path=data/report.csv&user_id=dylan"

Fetch all JSON files from a folder:

curl "http://localhost:38888/api/v2/fetch_files?type=json_folder&thread_id=550e8400-e29b-41d4-a716-446655440000&path=data/json_files&user_id=dylan"

Response Format:

• For csv/json: Returns content of the file
• For json_folder: Returns a dict mapping filename to content for all *.json files

Security:

• Path traversal protection is enforced
• Files must exist under /data/{user_id}/projects/{thread_id}/working_dir/{path}

Session Management

The agent supports session resumption based on thread_id. The project state (including the Claude SDK session ID) is stored in /data/${user_id}/projects/${thread_id}/working_dir/metadata.json.

To resume a session, include the thread_id in subsequent requests:

{
  "query": "continue with the next task",
  "thread_id": "previous_thread_id",
  "user_id": "dylan"
}

If a thread_id is provided but no existing session is found in the project metadata, the API will return an error.
