Open Swarm: Orchestrating AI Agent Swarms with Django

Open Swarm

Open Swarm is a Python framework for creating, managing, and deploying autonomous agent swarms. It leverages the openai-agents library for core agent functionality and provides a structured way to build complex, multi-agent workflows using Blueprints.

Open Swarm can be used in two primary ways:

1. As a CLI Utility (swarm-cli): Manage, run, and install blueprints directly on your local machine. Ideal for personal use, testing, and creating standalone agent tools. (Recommended installation: PyPI)
2. As an API Service (swarm-api): Deploy a web server that exposes your blueprints via an OpenAI-compatible REST API. Ideal for integrations, web UIs, and shared access. (Recommended deployment: Docker)

---

Core Concepts

• Agents: Individual AI units performing specific tasks, powered by LLMs (like GPT-4, Claude, etc.). Built using the openai-agents SDK.
• Blueprints: Python classes (BlueprintBase subclasses) defining a swarm's structure, agents, coordination logic, and external dependencies (like required environment variables or MCP servers). They act as reusable templates for specific tasks (e.g., code generation, research, data analysis).
• MCP (Model Context Protocol) Servers: Optional external processes providing specialized capabilities (tools) to agents, such as filesystem access, web browsing, database interaction, or interacting with specific APIs (Slack, Monday.com, etc.). Agents interact with MCP servers via a standardized communication protocol.
• Configuration (swarm_config.json): A central JSON file defining available LLM profiles (API keys, models) and configurations for MCP servers. Typically managed via swarm-cli in ~/.config/swarm/.
• swarm-cli: A command-line tool for managing blueprints (adding, listing, running, installing) and the swarm_config.json file. Uses XDG directories for storing blueprints (~/.local/share/swarm/blueprints/) and configuration (~/.config/swarm/).
• swarm-api: A launcher for the Django/DRF backend that exposes installed blueprints via an OpenAI-compatible REST API (/v1/models, /v1/chat/completions).

Environment Variables

Open Swarm and its blueprints use a variety of environment variables for configuration, security, and integration with external services. Set these in your shell, .env file, Docker environment, or deployment platform as appropriate.

Core Framework Environment Variables

Variable	Description	Default / Required
OPENAI_API_KEY	API key for OpenAI LLMs (used by agents and blueprints)	Required for OpenAI usage
SWARM_API_KEY	API key for securing API endpoints (swarm-api)	Optional (recommended)
LITELLM_BASE_URL	Override base URL for LiteLLM/OpenAI-compatible endpoints	Optional
LITELLM_API_KEY	API key for LiteLLM endpoints	Optional
SWARM_CONFIG_PATH	Path to the main Swarm config file (swarm_config.json)	../swarm_config.json
BLUEPRINT_DIRECTORY	Directory containing blueprint files	src/swarm/blueprints
DJANGO_SECRET_KEY	Django secret key (for API mode)	Auto-generated/dev default

Blueprint/Tool-Specific Variables

• Some blueprints and MCP tools may require additional env vars (e.g., Google API keys, Slack tokens, etc.).
• Refer to the blueprint's docstring or config for details.

Usage Example

export OPENAI_API_KEY="sk-..."
export SWARM_API_KEY="..."
export LITELLM_BASE_URL="https://open-litellm.fly.dev/v1"
# ... set other variables as needed

Toolbox Functionality

Open Swarm ships with a growing toolbox of agent and blueprint utilities. All features listed below have robust, passing tests unless marked as WIP (Work In Progress).

Task Scheduler Toolbox

• Schedule jobs with at:
  • Schedule a shell script or command to run at a specific time (uses the system at command).
  • Test Status: Passing
• List scheduled at jobs:
  • List all jobs currently scheduled with at.
  • Test Status: Passing
• Remove at jobs:
  • Remove a scheduled job by its job ID.
  • Test Status: Passing
• Schedule jobs with cron:
  • Schedule recurring jobs using cron expressions (uses the system crontab).
  • Test Status: Passing
• List scheduled cron jobs:
  • List all jobs currently scheduled with crontab.
  • Test Status: Passing
• Remove cron jobs:
  • Remove a scheduled cron job by its job ID.
  • Test Status: Passing

Slash Command Framework

• Global slash command registry:
  • Blueprints can register and use slash commands (e.g., /help, /agent, /model).
  • Built-in demo commands: /help, /agent, /model.
  • Test Status: Passing
• Blueprint Integration:
  • Blueprints can access the global registry and add their own commands.
  • Test Status: Passing

Usage Example (Slash Commands)

from swarm.extensions.blueprint.slash_commands import slash_command_registry

@slash_command_registry.register('/hello')
def hello_command(args):
    return f"Hello, {args}!"

Usage Example (Task Scheduler)

from swarm.extensions.task_scheduler_toolbox import schedule_at_job, list_at_jobs, remove_at_job

job_id = schedule_at_job('/path/to/script.sh', run_time='now + 5 minutes')
jobs = list_at_jobs()
remove_at_job(job_id)

Developer Notes

• System dependencies are mocked in tests for CI and portability.
• Any toolbox feature not listed as Passing above is considered WIP and may not be stable.
• Contributions and feedback are welcome!

Quickstart 1: Using swarm-cli Locally (via PyPI)

This is the recommended way to use swarm-cli for managing and running blueprints on your local machine.

Prerequisites:

• Python 3.10+
• pip (Python package installer)

Steps:

1. Install open-swarm from PyPI:

   pip install open-swarm
   

   (Using a virtual environment is recommended: python -m venv .venv && source .venv/bin/activate)

2. Initial Configuration (First Run):

   • The first time you run a swarm-cli command that requires configuration (like run or config), it will automatically create a default swarm_config.json at ~/.config/swarm/swarm_config.json if one doesn't exist.
   • You must set the required environment variables (like OPENAI_API_KEY) in your shell for the configuration to work. Create a .env file in your working directory or export them:

     export OPENAI_API_KEY="sk-..."
     # Add other keys as needed (GROQ_API_KEY, etc.)
     

   • You can customize the configuration further using swarm-cli config commands (see USERGUIDE.md).

3. Add a Blueprint:

   • Download or create a blueprint file (e.g., my_blueprint.py). Example blueprints are available in the project repository.
   • Add it using swarm-cli:

     # Example: Adding a downloaded blueprint file
     swarm-cli add ./path/to/downloaded/blueprint_echocraft.py
     
     # Example: Adding a directory containing a blueprint
     swarm-cli add ./my_custom_blueprints/agent_smith --name agent_smith
     

4. Run the Blueprint:

   • Single Instruction:

     swarm-cli run echocraft --instruction "Hello from CLI!"
     

   • Interactive Mode:

     swarm-cli run echocraft
     # Now you can chat with the blueprint interactively
     

5. (Optional) Install as Command:

   swarm-cli install echocraft
   # Now run (ensure ~/.local/share/swarm/bin is in your PATH):
   echocraft --instruction "I am a command now!"

Quickstart 2: Deploying swarm-api Service (via Docker)

This section covers deploying the API service using Docker.

Option A: Docker Compose (Recommended for Flexibility)

This method uses docker-compose.yaml and is best if you need to customize volumes, environment variables easily, or manage related services (like Redis).

Prerequisites:

• Docker (Install Docker)
• Docker Compose (Install Docker Compose)
• Git

Steps:

1. Clone the Repository: (Needed for docker-compose.yaml and config files)

   git clone https://github.com/matthewhand/open-swarm.git
   cd open-swarm
   

2. Configure Environment:

   • Copy cp .env.example .env and edit .env with your API keys (e.g., OPENAI_API_KEY, SWARM_API_KEY).

3. Prepare Blueprints & Config:

   • Place blueprints in ./blueprints.
   • Ensure ./swarm_config.json exists and is configured.

4. Configure Overrides (Optional):

   • Copy cp docker-compose.override.yaml.example docker-compose.override.yaml.
   • Edit the override file to mount additional volumes, change ports, etc.

5. Start the Service:

   docker compose up -d
   

6. Verify API: (Default port 8000)

   • Models: curl http://localhost:8000/v1/models
   • Chat: curl http://localhost:8000/v1/chat/completions -H "Content-Type: application/json" -d '{"model": "echocraft", ...}' (Add -H "Authorization: Bearer <key>" if needed).

Option B: Direct docker run (Simpler for Single Container)

This method runs the pre-built image directly from Docker Hub. Good for quick tests or simple deployments without cloning the repo. Customization requires careful use of -v (volume) and -e (environment) flags.

Prerequisites:

• Docker (Install Docker)

Steps:

1. Prepare Local Files (If Customizing):

   • Create a directory for your blueprints (e.g., ~/my_swarm_blueprints).
   • Create your swarm_config.json file locally (e.g., ~/my_swarm_config.json).
   • Create a .env file locally (e.g., ~/swarm.env) with your API keys (OPENAI_API_KEY, SWARM_API_KEY, etc.).

2. Run the Container:

   docker run -d \
     --name open-swarm-api \
     -p 8000:8000 \
     --env-file ~/swarm.env \
     -v ~/my_swarm_blueprints:/app/blueprints:ro \
     -v ~/my_swarm_config.json:/app/swarm_config.json:ro \
     -v open_swarm_db:/app/db.sqlite3 \
     --restart unless-stopped \
     mhand79/open-swarm:latest
   

   • -d: Run detached (in background).
   • --name: Assign a name to the container.
   • -p 8000:8000: Map host port 8000 to container port 8000 (adjust if needed).
   • --env-file: Load environment variables from your local file.
   • -v ...:/app/blueprints:ro: Mount your local blueprints directory (read-only). Required if you want to use custom blueprints.
   • -v ...:/app/swarm_config.json:ro: Mount your local config file (read-only). Required for custom LLM/MCP settings.
   • -v open_swarm_db:/app/db.sqlite3: Use a named Docker volume for the database to persist data.
   • --restart unless-stopped: Automatically restart the container unless manually stopped.
   • mhand79/open-swarm:latest: The image name on Docker Hub.

3. Verify API: (Same as Docker Compose)

   • Models: curl http://localhost:8000/v1/models
   • Chat: curl http://localhost:8000/v1/chat/completions ... (Add -H "Authorization: Bearer <key>" if needed).

Usage Modes Summary

• swarm-api (via Docker or manage.py runserver): Exposes blueprints as an OpenAI-compatible REST API. Ideal for integrations. Requires SWARM_API_KEY for security in non-local deployments.
• swarm-cli run (via PyPI install): Executes managed blueprints locally, either with a single instruction or in interactive chat mode. Good for testing and local tasks.
• swarm-cli install (via PyPI install): Creates standalone command-line executables from managed blueprints.
• Direct Python Execution (via Git clone): Running uv run python <blueprint_file.py> is mainly for development and testing individual files.
