Implementation Reference
- main.py:418-427 (handler)The asynchronous handler function for the 'query_ustensils' tool. It connects to a local MongoDB instance, queries the 'ustensils' collection in the 'recipies' database with an optional query dict, converts results to JSON-serializable format using _to_jsonable, and returns the list of documents.
async def query_ustensils(query: Optional[Dict] = None) -> List[Dict]: """Interroge la collection 'ustensils' de la base de données MongoDB 'recipies'.""" client = MongoClient('mongodb://localhost:27017/') db = client['recipies'] collection = db['ustensils'] query = query or {} results = list(collection.find(query)) client.close() return [_to_jsonable(doc) for doc in results] - main.py:414-417 (registration)The @mcp.tool decorator that registers the 'query_ustensils' tool, specifying its name and description.
@mcp.tool( name="query_ustensils", description="Queries the 'ustensils' collection of the 'recipies' MongoDB database.", ) - main.py:25-38 (helper)Helper utility function used by the 'query_ustensils' handler (and others) to recursively convert MongoDB documents containing ObjectId and datetime objects into JSON-serializable dictionaries.
