Features

• Execute Python snippets inside the namespace of a live target process.

• Connect using the there CLI, Python code, or Jupyter notebooks with %connect-there and %%there.

• Retrieve values, view logs, run shell commands, and transfer files.

• Produce structured JSON output for scripts and coding agents.

• Use SSH authentication and encrypted transport through AsyncSSH.

• Generate reviewable notebook cells from natural-language requests with %%there ai.

Installation

Install herethere in the Python environment that will start the server:

pip install herethere

If you want to connect from Jupyter using the IPython magics, install the magic extra in the notebook/client environment:

pip install "herethere[magic]"

Quickstart

from herethere.here import ServerConfig, start_server

state = {"speed": 1}

await start_server(ServerConfig.load(prefix="here"), namespace=globals())

there run --code "state['speed'] = 3"
there get "state"

there --json get "state"

%load_ext herethere.magic
%connect-there

%%there

print(state)
state["speed"] = 3
print(state)

Agent skill

herethere bundles an agent skill for using the there CLI. Install it for your project with Library Skills:

uvx library-skills

Trust model

A connected client can execute Python code inside the target process. Treat access to herethere like access to a Python REPL running inside your app.

Use it only for development workflows where you control both sides of the connection. Do not expose it publicly or give access to untrusted users.
