• tools: Tool configuration (parameters and settings for custom tools)
• mcp_servers: MCP server configuration
• settings: Global settings including Langfuse configuration

2. Interactive Agent/Chat Mode

Start an interactive session with an agent or model:

# Start an interactive agent session
eino-cli agent --agent search_agent

# Chat with a specific model
eino-cli agent --model gpt4

# Chat with tools
eino-cli agent --model gpt4 --tools duckduckgo_search,wikipedia_search

# Use a chat preset
eino-cli agent --chat search_chat

Parameter description:

• --agent, -a: Specify the agent name to run (optional)
• --chat, -c: Specify a chat preset name from configuration file (optional)
• --model, -m: Specify the model to chat with (required when not using --agent or --chat)
• --tools, -t: Specify available tools, separated by commas (optional when using --model directly)

3. Running an Agent

Use the run command to run a specified Agent:

eino-cli run --agent test_agent --prompt "Hello, please help me search for today's weather"

Parameter description:

• --agent, -a: Specify the Agent name to run (required)
• --prompt, -p: Specify the input prompt for the Agent (required)
