Minion

Minion is Agent's Brain. Minion is designed to execute any type of queries, offering a variety of features that demonstrate its flexibility and intelligence.

Installation

Install from PyPI

pip install minionx

# With optional dependencies
pip install minionx[litellm]      # LiteLLM support (100+ LLM providers)
pip install minionx[anthropic]   # Anthropic Claude
pip install minionx[bedrock]     # AWS Bedrock
pip install minionx[gradio]      # Gradio web UI
pip install minionx[all]         # All optional dependencies

Install from Source

git clone https://github.com/femto/minion.git && cd minion
pip install -e .
cp config/config.yaml.example config/config.yaml
cp config/.env.example config/.env

Docker Installation

git clone https://github.com/femto/minion.git && cd minion
cp config/config.yaml.example config/config.yaml

# Set your API key
export OPENAI_API_KEY=your-api-key

# Build and run (basic install)
docker-compose build
docker-compose run --rm minion

# Build with optional dependencies
docker-compose build --build-arg EXTRAS="gradio,web,anthropic"
# Or install all extras
docker-compose build --build-arg EXTRAS="all"

# Run a specific example
docker-compose run --rm minion python examples/mcp/mcp_agent_example.py

Edit config/config.yaml:

models:
  "default":
    api_type: "openai"
    base_url: "${DEFAULT_BASE_URL}"
    api_key: "${DEFAULT_API_KEY}"
    model: "gpt-4.1"
    temperature: 0

See Configuration for more details on configuration options.

Quick Start

Using CodeAgent (Recommended)

from minion.agents.code_agent import CodeAgent

# Create agent
agent = await CodeAgent.create(
    name="Minion Code Assistant",
    llm="your-model",
    tools=all_tools,  # optional
)

# Run task
async for event in await agent.run_async("your task here"):
    print(event)

See examples/mcp/mcp_agent_example.py for a complete example with MCP tools.

Using Brain

from minion.main.brain import Brain

brain = Brain()
obs, score, *_ = await brain.step(query="what's the solution 234*568")
print(obs)

See Brain Usage Guide for more examples.

Working Principle

The flowchart demonstrates the complete process from query to final result:

1. First receives the user query (Query)
2. System generates a solution (Solution)
3. Performs solution verification (Check)
4. If unsatisfactory, makes improvements (Improve) and returns to generate new solutions
5. If satisfactory, outputs the final result (Final Result)

Configuration

Configuration File Locations

1. Project Config: MINION_ROOT/config/config.yaml - Default project configuration
2. User Config: ~/.minion/config.yaml - User-specific overrides

Configuration Priority

When both configuration files exist:

• Project Config takes precedence over User Config

This allows you to:

• Keep sensitive data (API keys) in your user config
• Share project defaults through the project config

Environment Variables

Variable Substitution: Use ${VAR_NAME} syntax to reference environment variables directly in config values:

models:
  "default":
    api_key: "${OPENAI_API_KEY}"
    base_url: "${OPENAI_BASE_URL}"
    api_type: "openai"
    model: "gpt-4.1"
    temperature: 0.3
  "azure-gpt-4o":
    api_type: "azure"
    api_key: "${AZURE_OPENAI_API_KEY}"
    base_url: "${AZURE_OPENAI_ENDPOINT}"  # e.g., https://your-resource.openai.azure.com/
    api_version: "2024-06-01"
    model: "gpt-4o"  # deployment name
    temperature: 0

Loading .env Files: Use env_file to load environment variables from .env files (follows Docker .env file format):

env_file:
  - .env        # loaded first
  - .env.local  # loaded second, can override values from .env

Inline Environment Variables: Define environment variables directly in config:

environment:
  MY_VAR: "value"
  ANOTHER_VAR: "another_value"

Variables from all sources (system environment, .env files, inline environment) will be available for ${VAR_NAME} substitution throughout the configuration.

Supported API Types

api_type	Description	Required Fields
openai	OpenAI API or compatible (Ollama, vLLM, LocalAI)	api_key, base_url, model
azure	Azure OpenAI Service	api_key, base_url, api_version, model
azure_inference	Azure AI Model Inference (DeepSeek, Phi)	api_key, base_url, model
azure_anthropic	Azure hosted Anthropic models	api_key, base_url, model
bedrock	AWS Bedrock (sync)	access_key_id, secret_access_key, region, model
bedrock_async	AWS Bedrock (async, better performance)	access_key_id, secret_access_key, region, model
litellm	Unified interface for 100+ providers	api_key, model (with provider prefix)

LiteLLM Model Prefixes: Use anthropic/claude-3-5-sonnet, bedrock/anthropic.claude-3, gemini/gemini-1.5-pro, ollama/llama3.2, etc. See LiteLLM docs for all supported providers.

See config/config.yaml.example for complete examples of all supported providers.

MINION_ROOT Detection

MINION_ROOT is determined automatically:

1. Checks MINION_ROOT environment variable (if set)
2. Auto-detects by finding .git, .project_root, or .gitignore in parent directories
3. Falls back to current working directory

Check the startup log:

INFO | minion.const:get_minion_root:44 - MINION_ROOT set to: <some_path>

Warning: Be cautious - LLM can generate potentially harmful code.
