JupyterLab Integration
Available only when JupyterLab mode is enabled. It is enabled by default.
When running in JupyterLab mode, Jupyter MCP Server integrates with jupyter-mcp-tools to expose additional JupyterLab commands as MCP tools. By default, the following tools are enabled:
Name | Description |
| Execute all cells in the current notebook sequentially |
| Get information about the currently selected cell |
You can now customize which tools from jupyter-mcp-tools are available using the allowed_jupyter_mcp_tools configuration parameter. This allows you to enable additional notebook operations, console commands, file management tools, and more.
# Example: Enable additional tools via command-line
jupyter lab --port 4040 --IdentityProvider.token MY_TOKEN --JupyterMCPServerExtensionApp.allowed_jupyter_mcp_tools="notebook_run-all-cells,notebook_get-selected-cell,notebook_append-execute,console_create"For the complete list of available tools and detailed configuration instructions, please refer to the Additional Tools documentation.
📝 Prompt Overview
The server also supports prompt feature of MCP, providing a easy way for user to interact with Jupyter notebooks.
Name | Description |
| Cite specific cells from specified notebook (like |
For more details on each prompt, their input parameters, and return content, please refer to the official Prompt documentation.
🏁 Getting Started
For comprehensive setup instructions—including Streamable HTTP transport, running as a Jupyter Server extension and advanced configuration—check out our documentation. Or, get started quickly with JupyterLab and STDIO transport here below.
1. Set Up Your Environment
pip install jupyterlab==4.4.1 jupyter-collaboration==4.0.2 jupyter-mcp-tools>=0.1.4 ipykernel pycrdtTo confirm your environment is correctly configured:
Open a notebook in JupyterLab
Type some content in any cell (code or markdown)
Observe the tab indicator: you should see an "×" appear next to the notebook name, indicating unsaved changes
Wait a few seconds—the "×" should automatically change to a "●" without manually saving
This automatic saving behavior confirms that the real-time collaboration features are working properly, which is essential for MCP server integration.
2. Start JupyterLab
# Start JupyterLab on port 8888, allowing access from any IP and setting a token
jupyter lab --port 8888 --IdentityProvider.token MY_TOKEN --ip 0.0.0.0If you are running notebooks through JupyterHub instead of JupyterLab as above, refer to ourJupyterHub setup guide.
3. Configure Your Preferred MCP Client
Next, configure your MCP client to connect to the server. We offer two primary methods—choose the one that best fits your needs:
📦 Using
uvx(Recommended for Quick Start): A lightweight and fast method usinguv. Ideal for local development and first-time users.🐳 Using
Docker(Recommended for Production): A containerized approach that ensures a consistent and isolated environment, perfect for production or complex setups.
First, install uv:
pip install uv
uv --version
# should be 0.6.14 or higherSee more details on uv installation.
Then, configure your client:
{
"mcpServers": {
"jupyter": {
"command": "uvx",
"args": ["jupyter-mcp-server@latest"],
"env": {
"JUPYTER_URL": "http://localhost:8888",
"JUPYTER_TOKEN": "MY_TOKEN",
"ALLOW_IMG_OUTPUT": "true"
}
}
}
}On macOS and Windows:
{
"mcpServers": {
"jupyter": {
"command": "docker",
"args": [
"run", "-i", "--rm",
"-e", "JUPYTER_URL",
"-e", "JUPYTER_TOKEN",
"-e", "ALLOW_IMG_OUTPUT",
"datalayer/jupyter-mcp-server:latest"
],
"env": {
"JUPYTER_URL": "http://host.docker.internal:8888",
"JUPYTER_TOKEN": "MY_TOKEN",
"ALLOW_IMG_OUTPUT": "true"
}
}
}
}On Linux:
{
"mcpServers": {
"jupyter": {
"command": "docker",
"args": [
"run", "-i", "--rm",
"-e", "JUPYTER_URL",
"-e", "JUPYTER_TOKEN",
"-e", "ALLOW_IMG_OUTPUT",
"--network=host",
"datalayer/jupyter-mcp-server:latest"
],
"env": {
"JUPYTER_URL": "http://localhost:8888",
"JUPYTER_TOKEN": "MY_TOKEN",
"ALLOW_IMG_OUTPUT": "true"
}
}
}
}Port Configuration: Ensure the
portin your Jupyter URLs matches the one used in thejupyter labcommand. For simplified config, set this inJUPYTER_URL.Server Separation: Use
JUPYTER_URLwhen both services are on the same server, or set individual variables for advanced deployments. The different URL variables exist because some deployments separate notebook storage (DOCUMENT_URL) from kernel execution (RUNTIME_URL).Authentication: In most cases, document and runtime services use the same authentication token. Use
JUPYTER_TOKENfor simplified config or setDOCUMENT_TOKENandRUNTIME_TOKENindividually for different credentials.Notebook Path: The
DOCUMENT_IDparameter specifies the path to the notebook the MCP client default to connect. It should be relative to the directory where JupyterLab was started. If you omitDOCUMENT_ID, the MCP client can automatically list all available notebooks on the Jupyter server, allowing you to select one interactively via your prompts.Image Output: Set
ALLOW_IMG_OUTPUTtofalseif your LLM does not support mutimodel understanding.
For detailed instructions on configuring various MCP clients—including Claude Desktop, VS Code, Cursor, Cline, and Windsurf — see the Clients documentation.
✅ Best Practices
Interact with LLMs that supports multimodal input (like Gemini 2.5 Pro) to fully utilize advanced multimodal understanding capabilities.
Use a MCP client that supports returning image data and can parse it (like Cursor, Gemini CLI, etc.), as some clients may not support this feature.
Break down complex task (like the whole data science workflow) into multiple sub-tasks (like data cleaning, feature engineering, model training, model evaluation, etc.) and execute them step-by-step.
Provide clearly structured prompts and rules (👉 Visit our Prompt Templates to get started)
Provide as much context as possible (like already installed packages, field explanations for existing datasets, current working directory, detailed task requirements, etc.).

(not regex) and may span multiple lines. By default, old_string must appear exactly once;
set replace_all=True for multiple occurrences. Returns a diff of the changes made.
Prefer this over overwrite_cell_source for small, targeted edits — it is safer because
unchanged parts of the cell are left untouched. Use read_cell first to see the current
source and construct an accurate old_string.| Name | Required | Description | Default |

kernel-backed and sandbox-backed execution using the same execute_code API.
Targets the current activated notebook's kernel by default. Pass kernel_id
to execute in a specific kernel directly — including raw kernels with no
notebook attached.
Recommended to use in following cases:
1. Execute Jupyter magic commands(e.g., `%timeit`, `%pip install xxx`)
2. Performance profiling and debugging.
3. View intermediate variable values(e.g., `print(xxx)`, `df.head()`)
4. Temporary calculations and quick tests(e.g., `np.mean(df['xxx'])`)
5. Execute Shell commands in Jupyter server(e.g., `!git xxx`)
Under no circumstances should you use this tool to:
1. Import new modules or perform variable assignments that affect subsequent Notebook execution
2. Execute dangerous code that may harm the Jupyter server or the user's data without permission

Scored across 18 tools
Most tools have clear, distinct purposes, especially with explicit guidance distinguishing edit_cell_source from overwrite_cell_source. The three execution-related tools (execute_cell, insert_execute_code_cell, execute_code) could be confused at first glance, but their descriptions clarify the differences.
The set largely follows a verb_noun pattern (read_cell, delete_cell, move_cell, restart_notebook). Minor inconsistencies like insert_execute_code_cell and unuse_notebook break the rhythm slightly, but the pattern remains predictable overall.
18 tools is on the heavier side but reasonable for a Jupyter notebook server covering connection, notebook lifecycle, cell operations, execution, and file/kernel browsing. The count is justified by the breadth of operations rather than redundancy.
The set covers notebook activation, cell reading/writing/execution/movement/deletion, kernel restarts, and dynamic connection. Missing operations like creating/saving notebooks or managing kernels beyond restarting are notable but do not severely undermine the core workflow.
