Disclosure
Datalayer-maintained open source MCP server for Jupyter, published as the `jupyter-mcp-server` Python package under the BSD 3-Clause license.
Jupyter MCP Server connects Claude and other MCP clients to Jupyter notebooks.
It exposes tools for browsing server files and kernels, selecting notebooks,
reading notebook contents, editing cells, executing code, restarting kernels,
and returning notebook outputs including images and plots.
Use it when Claude needs supervised access to a Jupyter environment for data
science, research notebooks, reproducible experiments, interactive teaching,
or notebook maintenance workflows.
These sources were reviewed on 2026-06-06. Prefer the live repository,
README, PyPI metadata, license, package manifest, architecture notes, CLI
entrypoint, server implementation, runtime configuration, and tool registry
for current setup and behavior details.
Features
Connect to local, remote, or hosted Jupyter notebook deployments.
List files and directories visible to the Jupyter server.
List available and running kernel sessions.
Create, select, switch, read, restart, and disconnect notebooks.
Read individual cells and full notebook contents.
Insert, delete, move, overwrite, and surgically edit cell source.
Execute individual cells or direct kernel code.
Return text, image, plot, and other notebook output types.
Use stdio for local MCP clients or Streamable HTTP for hosted clients.
Integrate with selected JupyterLab commands through jupyter-mcp-tools.
Installation
Start or identify the Jupyter server that Claude should control, then configure
the MCP client with the published package:
For Streamable HTTP deployments, configure an MCP_TOKEN for bearer-token
authentication unless the server is intentionally limited to trusted local
testing.
Use Cases
Ask Claude to inspect a notebook and summarize its cells and outputs.
Insert or update code cells in a controlled analysis notebook.
Execute a cell and use the returned output to fix errors or refine analysis.
Generate, inspect, and iterate on plots from a data-science notebook.
Switch between notebooks in a shared Jupyter workspace.
Restart a kernel and rerun selected cells during troubleshooting.
Use Claude as a notebook assistant in teaching, research, or exploratory
prototyping environments.
Safety and Privacy
Jupyter MCP Server gives Claude operational access to notebooks and kernels.
Connect it to disposable notebooks first, review every code-execution request,
and keep it away from notebooks that hold production credentials or sensitive
research unless you have an explicit approval workflow.
Notebook outputs and error traces often contain private paths, secrets, data
samples, or screenshots. Treat MCP transcripts and notebook logs as sensitive
artifacts, especially when ALLOW_IMG_OUTPUT is enabled or when the connected
Jupyter server belongs to a shared team or JupyterHub deployment.

How it compares
Jupyter MCP Server side by side with 3 alternatives on trust, install, platform support, and disclosed safety notes — all from reviewed registry metadata.
MCP server for connecting Claude to Jupyter notebooks, kernels, files, cells, multimodal outputs, and JupyterLab workflows over stdio or Streamable HTTP.
Connect Claude to a Google Colab runtime. Colab MCP starts a local FastMCP server and websocket proxy, waits for an authorized Colab-origin browser connection, then exposes the session's notebook and runtime tools to your MCP client over stdio.
MCP support in Azure Data API Builder for exposing configured database entities as MCP tools, including entity discovery and DML operations over Azure databases and supported on-premises data stores.
Official data.gouv.fr MCP server for searching French national open datasets, exploring organizations and data services, inspecting resources, querying tabular data, and retrieving dataset metrics through Claude.
✓Jupyter MCP Server can list files, list kernels, create or switch notebooks, insert cells, edit cell source, delete cells, move cells, restart kernels, execute cells, and execute arbitrary code in a notebook kernel.
Notebook code can read files available to the Jupyter process, access environment variables, call network services, start subprocesses, install packages, or mutate data depending on kernel permissions.
File and notebook tools can alter important notebooks or delete work if pointed at the wrong server, path, notebook, or cell index.
Keep Claude connected only to isolated kernels and directories that are appropriate for agent-driven execution.
Use least-privilege Jupyter tokens, short-lived sessions, and a separate test notebook before allowing changes in production or shared JupyterHub environments.
Streamable HTTP deployments require MCP client authentication unless explicitly started in insecure no-auth mode; do not expose no-auth transports beyond trusted local testing.
✓Colab MCP runs a local websocket proxy and waits for a Google Colab browser session to connect before proxying session tools.
The server creates a bearer-style proxy token and accepts a single authorized Colab-origin websocket connection at a time.
A connected Colab runtime can execute code and interact with notebooks, outputs, files, variables, packages, and mounted resources depending on the session and tools exposed by Colab.
Use disposable notebooks or reviewed development sessions before allowing Claude to run code or inspect outputs.
Avoid connecting notebooks that have access to production data, cloud credentials, private datasets, paid accelerators, or long-running jobs unless the workflow has explicit approval.
✓Data API Builder MCP tools can expose database entity metadata and perform DML operations depending on DAB configuration and permissions.
Built-in tools include entity discovery and record read, create, update, delete, aggregate, and execute-style workflows in the MCP source tree.
The upstream README still labels endpoint support as coming soon while source, samples, and testing docs expose MCP behavior; verify the exact release before production use.
Use least-privilege roles, disable DML tools where not required, and require approval before write, delete, execute, or stored-procedure operations.
Do not connect MCP clients to production databases without backups, audit logging, query limits, and rollback procedures.
✓The hosted endpoint is documented as publicly available without access restrictions, so treat requests and returned public-data context as externally visible.
Tools are read-only but can retrieve dataset metadata, resource URLs, rows from tabular resources, service OpenAPI specs, metrics, and organization details that may influence decisions.
Public open data can be stale, incomplete, licensed with reuse conditions, or unsuitable for operational decisions without checking the dataset publisher and update cadence.
Tabular queries can return rows from large resources; use small page sizes and pagination instead of asking an agent to pull entire datasets through chat.
If self-hosting, review MCP_HOST, allowed hosts, allowed origins, Sentry, Matomo, and API-environment settings before exposing the server.
Privacy notes
✓Jupyter tokens, notebook contents, code cells, markdown cells, outputs, plots, image data, file names, kernel lists, environment-derived values, and error traces can be exposed to the MCP client.
Executed notebook cells may print secrets, local paths, database results, API responses, or private research data into model context or client logs.
Multimodal output support can send generated plots and images to the MCP client; disable or scope `ALLOW_IMG_OUTPUT` when images may contain sensitive data.
Shared notebooks and JupyterHub deployments may contain other users' work; confirm workspace boundaries before connecting an agent.
Retain notebook execution logs, MCP logs, and generated outputs only as long as needed for the workflow.
✓Notebook code, prompts, outputs, logs, variables, datasets, file paths, runtime metadata, package lists, browser session details, and generated websocket tokens can be visible to the MCP client and model provider.
Colab notebooks may contain API keys, OAuth tokens, mounted Drive paths, secrets in environment variables, private model weights, customer data, or unpublished research.
Local log files are created under a temporary Colab MCP log directory by default unless a log directory is specified.
Review Google Colab, MCP client, model provider, and organization retention policies before sending notebook or runtime context to an assistant.
✓Entity metadata can expose database names, table names, view names, stored procedure names, field names, key fields, relationships, permissions, and role design.
Read and DML tool calls can expose or change customer records, internal data, regulated fields, identifiers, audit fields, and business workflow state.
Connection strings, role headers, MCP URLs, logs, request bodies, result payloads, and MCP transcripts can contain sensitive operational or personal data.
Redact database values, connection details, entity names, role names, and query results before sharing prompts, screenshots, logs, or generated notes.
✓Search terms, dataset interests, resource IDs, user-agent headers, request URLs, tool names, and returned dataset rows may be visible to the hosted MCP service, MCP client, model provider, and logs.
The server includes optional Matomo and Sentry instrumentation in source; hosted deployments may apply their own analytics and error-reporting policies.
Public datasets can still contain personal data, geographic sensitivity, business identifiers, or regulated information; review source metadata and reuse terms before sharing results.
Avoid placing private investigation notes, customer context, or unpublished analysis inside prompts when a generic dataset search is enough.
