I have been working for the past few months on a SDK to provide LangGraph tools to easily allow users to connect their personal data to applications.
For now, it supports Telegram and Google (Gmail, Calendar, Youtube, Drive etc.) data, but it's open source and designed for anyone to contribute new connectors (Spotify, Slack and others are in progress).
It's called the PersonalAgentKit and currently provides a set of typescript tools for LangGraph.
There is some documentation on the PersonalAgentKit here: https://docs.verida.ai/integrations/overview and a demo video showing how to use the LangGraph tools here: https://docs.verida.ai/integrations/langgraph
I'm keen for developers to have a play and provide some feedback.
