Indexes the coding-agent sessions already sitting on your disk — months of history from before you installed it — and serves them back over MCP. 3.5 GB searched in ~1.5 ms, no LLM, no embeddings.
Jupyter MCP Server
Summary
Drive live Jupyter notebooks from an agent — read and edit cells, execute code, see rich outputs, and run against local JupyterLab or a cloud sandbox.
Features
- Read, insert, edit and execute cells in a live notebook
- Multimodal outputs — return plots and images back to the agent
- Manage multiple notebooks in a single session
- Code-sandbox variants for Datalayer, Kaggle, Google Colab and Modal
- STDIO, Streamable HTTP and Jupyter Server extension transports
- Claude Code plugin and a hosted deployment option

Description
Datalayer's Jupyter MCP Server connects an agent to a running Jupyter kernel rather than to notebook files on disk. That distinction is the whole point: the agent can insert and edit cells, execute them, read the outputs — including images, when ALLOW_IMG_OUTPUT is enabled — and iterate the way a person would, with state carried between cells instead of re-running a script from scratch each time.
It handles multiple notebooks in one session, exposes server and sandbox management tools alongside cell operations, and ships MCP prompts as well as tools. A JupyterLab integration adds further tools that can be switched on at the command line.
Where the kernel lives is configurable. Beyond a local JupyterLab, sandbox variants run the code on Datalayer, Kaggle (batch or interactive, with optional GPU), Google Colab or Modal, so the same agent workflow scales from a laptop to accelerated cloud compute. A hosted version of the server is also available, and there is a Claude Code plugin (/plugin marketplace add datalayer/jupyter-mcp-server).
Setup is a short list: pip install jupyterlab jupyter-collaboration jupyter-mcp-tools ipykernel, start JupyterLab with a token, then point the client at it. Distributed under the BSD 3-Clause licence.
