Pydantic AI Kernel

This is wrapper around pydantic-ai agent, that allows to request it through jupyter kernel messaging protocol.

We support :

streaming output,
multi-type output (markdown, raw text), and soon : images, audio, jupyter widgets
API's for accessing the agent :
- classical ZeroMQ jupyter kernel API
- web socket API, with jupyter kernel gateway
user-approval (human in the loop) with input_request messages
any pydantic-ai agent can be wrapped in this kernel
basic configuration through metakernel magics (agent history, tool list, mcp server, output formatter, ...)

Documentation : https://mariusgarenaux.github.io/pydantic-ai-kernel

Getting started

Within a python venv,

pip install pydantic-ai-kernel

Any jupyter frontend should be able to dialog with this kernel, for example :

• CLI : Install jupyter-console (pip install jupyter-console); and run jupyter console --kernel pydantic_ai

• Notebook (you might need to restart the IDE) : select 'pydantic_ai' on top right of the notebook

• Jupyter Lab : see [Jupyter Lab]

• jpterm : a fancy jupyter lab interface, in the terminal ! https://davidbrochart.github.io/jpterm/

• Silik Signal Messaging : Access the kernel through Signal Message Application, see here

For example :

jupyter console --kernel pydantic_ai

In the kernel, send :

%config

to create the config file, and start chat. See documentation for more informations.

%help <magic_name> and %magic will give you appropriate documentation

TAB completion for magic can be broken with older metakernel versions (before 1.0.4). To fix it, install the 1.0.4 manually :

uv add "metakernel @ git+https://github.com/Calysto/metakernel.git@afd3ddd"

or without uv:

git clone https://github.com/Calysto/metakernel
cd metakernel
git checkout afd3ddd
pip install -e .
cd ..
