MongoDB Stitch now supports the MongoDB wire protocol, allowing developers to access their Stitch apps using existing drivers such as PyMongo and tools like the mongo shell. The connection string can be used in a similar way to other languages, replacing username and password with an existing Stitch user. Developers can use this approach to work with data and access services and functions from their app server, without having to change their existing code or switch to a different language. By leveraging the MongoDB wire protocol, developers can continue to utilize their favorite tools and workflows while still benefiting from the features of MongoDB Stitch.
