This loader loads documents from MongoDB. The user specifies a Mongo instance to initialize the reader. They then specify the collection name and query params to fetch the relevant docs.

Usage

Here's an example usage of the SimpleMongoReader.

from llama_index import download_loader
import os

SimpleMongoReader = download_loader('SimpleMongoReader')

host = "<host>"
port = "<port>"
db_name = "<db_name>"
collection_name = "<collection_name>"
# query_dict is passed into db.collection.find()
query_dict = {}
reader = SimpleMongoReader(host, port)
documents = reader.load_data(db_name, collection_name, query_dict=query_dict)

This loader is designed to be used as a way to load data into LlamaIndex and/or subsequently used as a Tool in a LangChain Agent. See here for examples.
