Example with Llama Stack

You can use this server with Llama Stack to provide document processing capabilities to your LLM applications. Make sure you have a running Llama Stack server, then configure your INFERENCE_MODEL

from llama_stack_client.lib.agents.agent import Agent
from llama_stack_client.lib.agents.event_logger import EventLogger
from llama_stack_client.types.agent_create_params import AgentConfig
from llama_stack_client.types.shared_params.url import URL
from llama_stack_client import LlamaStackClient
import os

# Set your model ID
model_id = os.environ["INFERENCE_MODEL"]
client = LlamaStackClient(
    base_url=f"http://localhost:{os.environ.get('LLAMA_STACK_PORT', '8080')}"
)

# Register MCP tools
client.toolgroups.register(
    toolgroup_id="mcp::docling",
    provider_id="model-context-protocol",
    mcp_endpoint=URL(uri="http://0.0.0.0:8000/sse"))

# Define an agent with MCP toolgroup
agent_config = AgentConfig(
    model=model_id,
    instructions="""You are a helpful assistant with access to tools to manipulate documents.
Always use the appropriate tool when asked to process documents.""",
    toolgroups=["mcp::docling"],
    tool_choice="auto",
    max_tool_calls=3,
)

# Create the agent
agent = Agent(client, agent_config)

# Create a session
session_id = agent.create_session("test-session")

def _summary_and_qna(source: str):
    # Define the prompt
    run_turn(f"Please convert the document at {source} to markdown and summarize its content.")
    run_turn(f"Please generate a Q&A document with 3 items for source at {source} and display it in YAML format.")

def _run_turn(prompt):
    # Create a turn
    response = agent.create_turn(
        messages=[
            {
                "role": "user",
                "content": prompt,
            }
        ],
        session_id=session_id,
    )

    # Log the response
    for log in EventLogger().log(response):
        log.print()

_summary_and_qna('https://arxiv.org/pdf/2004.07606')
