Usage

Quick Start (Recommended)

import asyncio
from mistralai.async_client import MistralAsyncClient
from metorial import Metorial

async def main():
  # Initialize clients
  metorial = Metorial(api_key="...your-metorial-api-key...") # async by default
  mistral_client = MistralAsyncClient(
    api_key="...your-mistral-api-key..."
  )
  
  # One-liner chat with automatic session management
  response = await metorial.run(
    "What are the latest commits in the metorial/websocket-explorer repository?",
    "...your-mcp-server-deployment-id...", # can also be list
    mistral_client,
    model="mistral-large-latest",
    max_iterations=25
  )
  
  print("Response:", response)

asyncio.run(main())

Streaming Chat

import asyncio
from mistralai.async_client import MistralAsyncClient
from metorial import Metorial
from metorial.types import StreamEventType

async def streaming_example():
  # Initialize clients
  metorial = Metorial(api_key="...your-metorial-api-key...")
  mistral_client = MistralAsyncClient(
    api_key="...your-mistral-api-key..."
  )
  
  # Streaming chat with real-time responses
  async def stream_action(session):
    messages = [
      {"role": "user", "content": "Explain quantum computing"}
    ]
    
    async for event in metorial.stream(
      mistral_client, session, messages, 
      model="mistral-large-latest",
      max_iterations=25
    ):
      if event.type == StreamEventType.CONTENT:
        print(f"🤖 {event.content}", end="", flush=True)
      elif event.type == StreamEventType.TOOL_CALL:
        print(f"\n🔧 Executing {len(event.tool_calls)} tool(s)...")
      elif event.type == StreamEventType.COMPLETE:
        print(f"\n✅ Complete!")
  
  await metorial.with_session("...your-server-deployment-id...", stream_action)

asyncio.run(streaming_example())

Advanced Usage with Session Management

import asyncio
from mistralai.client import MistralClient
from mistralai.models.chat_completion import ChatMessage
from metorial import Metorial
from metorial_mistral import MetorialMistralSession

async def main():
  # Initialize clients
  metorial = Metorial(api_key="...your-metorial-api-key...")
  mistral = MistralClient(api_key="...your-mistral-api-key...")
  
  # Create session with your server deployments
  async with metorial.session(["...your-server-deployment-id..."]) as session:
    # Create Mistral-specific wrapper
    mistral_session = MetorialMistralSession(session.tool_manager)
    
    messages = [
      ChatMessage(role="user", content="What are the latest commits?")
    ]
    
    response = mistral.chat(
      model="mistral-large-latest",
      messages=messages,
      tools=mistral_session.tools
    )
    
    # Handle tool calls
    if response.choices[0].message.tool_calls:
      tool_responses = await mistral_session.call_tools(response.choices[0].message.tool_calls)
      
      # Add assistant message and tool responses
      messages.append(response.choices[0].message)
      messages.extend(tool_responses)
      
      # Continue conversation...

asyncio.run(main())

Using Convenience Functions

from metorial_mistral import build_mistral_tools, call_mistral_tools

async def example_with_functions():
  # Get tools in Mistral format
  tools = build_mistral_tools(tool_manager)
  
  # Call tools from Mistral response
  tool_messages = await call_mistral_tools(tool_manager, tool_calls)

API Reference

MetorialMistralSession

Main session class for Mistral integration.

session = MetorialMistralSession(tool_manager)

Properties:

• tools: List of tools in Mistral format

Methods:

• async call_tools(tool_calls): Execute tool calls and return tool messages

build_mistral_tools(tool_mgr)

Build Mistral-compatible tool definitions.

Returns: List of tool definitions in Mistral format

call_mistral_tools(tool_mgr, tool_calls)

Execute tool calls from Mistral response.

Returns: List of tool messages

Tool Format

Tools are converted to Mistral's function calling format:

{
  "type": "function",
  "function": {
    "name": "tool_name",
    "description": "Tool description",
    "parameters": {
      "type": "object",
      "properties": {...},
      "required": [...]
    },
    "strict": True
  }
}

Error Handling

try:
    tool_messages = await mistral_session.call_tools(tool_calls)
except Exception as e:
    print(f"Tool execution failed: {e}")

Tool errors are returned as tool messages with error content.
