Keboola MCP Server

Connect your AI agents, MCP clients (Cursor, Claude, Windsurf, VS Code ...) and other AI assistants to Keboola. Expose data, transformations, SQL queries, and job triggers—no glue code required. Deliver the right data to agents when and where they need it.

Overview

Keboola MCP Server is an open-source bridge between your Keboola project and modern AI tools. It turns Keboola features—like storage access, SQL transformations, and job triggers—into callable tools for Claude, Cursor, CrewAI, LangChain, Amazon Q, and more.

Quick Start
Local Setup

Features

With the AI Agent and MCP Server, you can:

Storage: Query tables directly and manage table or bucket descriptions
Components: Create, List and inspect extractors, writers, data apps, and transformation configurations
SQL: Create SQL transformations with natural language
Jobs: Run components and transformations, and retrieve job execution details
Flows: Build and manage workflow pipelines using Conditional Flows and Orchestrator Flows.
Data Apps: Create, deploy and manage Keboola Streamlit Data Apps displaying your queries over storage data.
Metadata: Search, read, and update project documentation and object metadata using natural language
Dev Branches: Work safely in development branches outside of production, where all operations are scoped to the selected branch.

🚀 Quick Start: Remote MCP Server (Easiest Way)

The easiest way to use Keboola MCP Server is through our Remote MCP Server. This hosted solution eliminates the need for local setup, configuration, or installation.

What is the Remote MCP Server?

Our remote server is hosted on every multi-tenant Keboola stack and supports OAuth authentication. You can connect to it from any AI assistant that supports remote SSE connection and OAuth authentication.

How to Connect

Get your remote server URL: Navigate to your Keboola Project Settings → MCP Server tab
Copy the server URL: It will look like https://mcp.<YOUR_REGION>.keboola.com/sse
Configure your AI assistant: Paste the URL into your AI assistant's MCP settings
Authenticate: You'll be prompted to authenticate with your Keboola account and select your project

Supported Clients

Cursor: Use the "Install In Cursor" button in your project's MCP Server settings or click this button
Claude Desktop: Add the integration via Settings → Integrations
Claude Code: Install using claude mcp add --transport http keboola <URL> (see below for details)
Windsurf: Configure with the remote server URL
Make: Configure with the remote server URL
Other MCP clients: Configure with the remote server URL

Claude Code Setup

Claude Code is a command-line interface tool that allows you to interact with Claude using your terminal. You can install the Keboola MCP Server integration using a simple command.

Installation:

Run the following command in your terminal, replacing <YOUR_REGION> with your Keboola region:

claude mcp add --transport http keboola https://mcp.<YOUR_REGION>.keboola.com/mcp

Region-specific commands:

Region	Installation Command
US Virginia AWS	`claude mcp add --transport http keboola https://mcp.keboola.com/mcp`
US Virginia GCP	`claude mcp add --transport http keboola https://mcp.us-east4.gcp.keboola.com/mcp`
EU Frankfurt AWS	`claude mcp add --transport http keboola https://mcp.eu-central-1.keboola.com/mcp`
EU Ireland Azure	`claude mcp add --transport http keboola https://mcp.north-europe.azure.keboola.com/mcp`
EU Frankfurt GCP	`claude mcp add --transport http keboola https://mcp.europe-west3.gcp.keboola.com/mcp`

Usage:

Once installed, you can use the Keboola MCP Server in Claude Code by typing /mcp in your conversation and selecting the Keboola tools you want to use.

Authentication:

When you first use the Keboola MCP Server in Claude Code, a browser window will open prompting you to:

Log in with your Keboola account
Select the project you want to connect to
Authorize the connection

After authentication, you can start using Keboola tools directly from Claude Code.

For detailed setup instructions and region-specific URLs, see our Remote Server Setup documentation.

Using Development Branches

You can work safely in Keboola development branches without affecting your production data. The remotely hosted MCP Servers respect the KBC_BRANCH_ID parameter and will scope all operations to the specified branch. You can find the development branch ID in the URL when navigating to the development branch in the UI, for example: https://connection.us-east4.gcp.keboola.com/admin/projects/PROJECT_ID/branch/BRANCH_ID/dashboard. The branch ID must be included in each request using the header X-Branch-Id: <branchId>, otherwise the MCP Server uses production branch as default. This should be managed by the AI client or the environment handling the server connection.

Local MCP Server Setup (Custom or Dev Way)

Run the MCP server on your own machine for full control and easy development. Choose this when you want to customize tools, debug locally, or iterate quickly. You’ll clone the repo, set Keboola credentials via environment variables or headers depending on the server transport, install dependencies, and start the server. This approach offers maximum flexibility (custom tools, local logging, offline iteration) but requires manual setup and you manage updates and secrets yourself.

The server supports multiple transport options, which can be selected by providing the --transport <transport> argument when starting the server:

stdio - Default when --transport is not specified. Standard input/output, typically used for local deployment with a single client.
streamable-http - Runs the server remotely over HTTP with a bidirectional streaming channel, allowing the client and server to continuously exchange messages. Connect via /mcp (e.g., http://localhost:8000/mcp).
sse - Deprecated, use streamable-http instead. Runs the server remotely using Server-Sent Events (SSE) for one-way event streaming from server to client. Connect via /sse (e.g., http://localhost:8000/sse).
http-compat - A custom transport supporting both SSE and streamable-http. It is currently used on Keboola remote servers but will soon be replaced by streamable-http only.

For client–server communication, Keboola credentials must be provided to enable working with your project in your Keboola Region. The following are required: KBC_STORAGE_TOKEN, KBC_STORAGE_API_URL, KBC_WORKSPACE_SCHEMA and optionally KBC_BRANCH_ID. You can provide these in two ways:

For personal use (mainly with stdio transport): set the environment variables before starting the server. All requests will reuse these predefined credentials.
For multi-user use: include the variables in the request headers so that each request uses the credentials provided with it.

KBC_STORAGE_TOKEN

This is your authentication token for Keboola:

For instructions on how to create and manage Storage API tokens, refer to the official Keboola documentation.

Note: If you want the MCP server to have limited access, use custom storage token, if you want the MCP to access everything in your project, use the master token.

KBC_WORKSPACE_SCHEMA

This identifies your workspace in Keboola and is used for SQL queries. However, this is only required if you're using a custom storage token instead of the Master Token:

If using Master Token: The workspace is created automatically behind the scenes
If using custom storage token: Follow this Keboola guide to get your KBC_WORKSPACE_SCHEMA

Note: When creating a workspace manually, check Grant read-only access to all Project data option

Note: KBC_WORKSPACE_SCHEMA is called Dataset Name in BigQuery workspaces, you simply click connect and copy the Dataset Name

KBC_STORAGE_API_URL (Keboola Region)

Your Keboola Region API URL depends on your deployment region. You can determine your region by looking at the URL in your browser when logged into your Keboola project:

Region	API URL
AWS North America	`https://connection.keboola.com`
AWS Europe	`https://connection.eu-central-1.keboola.com`
Google Cloud EU	`https://connection.europe-west3.gcp.keboola.com`
Google Cloud US	`https://connection.us-east4.gcp.keboola.com`
Azure EU	`https://connection.north-europe.azure.keboola.com`

KBC_BRANCH_ID (Optional)

To operate on a specific Keboola development branch, set the branch ID using the KBC_BRANCH_ID parameter. The MCP server scopes its functionality to the specified branch, ensuring all changes remain isolated and do not impact the production branch.

If not provided, the server uses the production branch by default.
For development work, set KBC_BRANCH_ID to the numeric ID of your branch (e.g., 123456). You can find the development branch ID in the URL when navigating to the development branch in the UI, for example: https://connection.us-east4.gcp.keboola.com/admin/projects/PROJECT_ID/branch/BRANCH_ID/dashboard.
On remote transports, you can override per-request with the HTTP header X-Branch-Id: <branchId> or KBC_BRANCH_ID: <branchId>.

Installation

Make sure you have:

Python 3.10+ installed
Access to a Keboola project with admin rights
Your preferred MCP client (Claude, Cursor, etc.)

Note: Make sure you have uv installed. The MCP client will use it to automatically download and run the Keboola MCP Server. Installing uv:

macOS/Linux:

#if homebrew is not installed on your machine use:
# /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install using Homebrew
brew install uv

Windows:

# Using the installer script
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

# Or using pip
pip install uv

# Or using winget
winget install --id=astral-sh.uv -e

For more installation options, see the official uv documentation.

Running Keboola MCP Server

There are four ways to use the Keboola MCP Server, depending on your needs:

Option A: Integrated Mode (Recommended)

In this mode, Claude or Cursor automatically starts the MCP server for you. You do not need to run any commands in your terminal.

Configure your MCP client (Claude/Cursor) with the appropriate settings
The client will automatically launch the MCP server when needed

Claude Desktop Configuration

Go to Claude (top left corner of your screen) -> Settings → Developer → Edit Config (if you don't see the claude_desktop_config.json, create it)
Add the following configuration:
Restart Claude desktop for changes to take effect

{
  "mcpServers": {
    "keboola": {
      "command": "uvx",
      "args": ["keboola_mcp_server --transport <transport>"],
      "env": {
        "KBC_STORAGE_API_URL": "https://connection.YOUR_REGION.keboola.com",
        "KBC_STORAGE_TOKEN": "your_keboola_storage_token",
        "KBC_WORKSPACE_SCHEMA": "your_workspace_schema",
        "KBC_BRANCH_ID": "your_branch_id_optional"
      }
    }
  }
}

Config file locations:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Cursor Configuration

Go to Settings → MCP
Click "+ Add new global MCP Server"
Configure with these settings:

{
  "mcpServers": {
    "keboola": {
      "command": "uvx",
      "args": ["keboola_mcp_server --transport <transport>"],
      "env": {
        "KBC_STORAGE_API_URL": "https://connection.YOUR_REGION.keboola.com",
        "KBC_STORAGE_TOKEN": "your_keboola_storage_token",
        "KBC_WORKSPACE_SCHEMA": "your_workspace_schema",
        "KBC_BRANCH_ID": "your_branch_id_optional"
      }
    }
  }
}

Note: Use short, descriptive names for MCP servers. Since the full tool name includes the server name and must stay under ~60 characters, longer names may be filtered out in Cursor and will not be displayed to the Agent.

Cursor Configuration for Windows WSL

When running the MCP server from Windows Subsystem for Linux with Cursor AI, use this configuration:

{
  "mcpServers": {
    "keboola":{
      "command": "wsl.exe",
      "args": [
          "bash",
          "-c '",
          "export KBC_STORAGE_API_URL=https://connection.YOUR_REGION.keboola.com &&",
          "export KBC_STORAGE_TOKEN=your_keboola_storage_token &&",
          "export KBC_WORKSPACE_SCHEMA=your_workspace_schema &&",
          "export KBC_BRANCH_ID=your_branch_id_optional &&",
          "/snap/bin/uvx keboola_mcp_server --transport <transport>",
          "'"
      ]
    }
  }
}

Option B: Local Development Mode

For developers working on the MCP server code itself:

Clone the repository and set up a local environment
Configure Claude/Cursor to use your local Python path:

{
  "mcpServers": {
    "keboola": {
      "command": "/absolute/path/to/.venv/bin/python",
      "args": [
        "-m",
        "keboola_mcp_server --transport <transport>"
      ],
      "env": {
        "KBC_STORAGE_API_URL": "https://connection.YOUR_REGION.keboola.com",
        "KBC_STORAGE_TOKEN": "your_keboola_storage_token",
        "KBC_WORKSPACE_SCHEMA": "your_workspace_schema",
        "KBC_BRANCH_ID": "your_branch_id_optional"
      }
    }
  }
}

Option C: Manual CLI Mode (For Testing Only)

You can run the server manually in a terminal for testing or debugging:

# Set environment variables
export KBC_STORAGE_API_URL=https://connection.YOUR_REGION.keboola.com
export KBC_STORAGE_TOKEN=your_keboola_storage_token
export KBC_WORKSPACE_SCHEMA=your_workspace_schema
export KBC_BRANCH_ID=your_branch_id_optional

uvx keboola_mcp_server --transport sse

Note: This mode is primarily for debugging or testing. For normal use with Claude or Cursor, you do not need to manually run the server.

Note: The server will use the SSE transport and listen on localhost:8000 for the incoming SSE connections. You can use --port and --host parameters to make it listen elsewhere.

Option D: Using Docker

docker pull keboola/mcp-server:latest

docker run \
  --name keboola_mcp_server \
  --rm \
  -it \
  -p 127.0.0.1:8000:8000 \
  -e KBC_STORAGE_API_URL="https://connection.YOUR_REGION.keboola.com" \
  -e KBC_STORAGE_TOKEN="YOUR_KEBOOLA_STORAGE_TOKEN" \
  -e KBC_WORKSPACE_SCHEMA="YOUR_WORKSPACE_SCHEMA" \
  -e KBC_BRANCH_ID="YOUR_BRANCH_ID_OPTIONAL" \
  keboola/mcp-server:latest \
  --transport sse \
  --host 0.0.0.0

Note: The server will use the SSE transport and listen on localhost:8000 for the incoming SSE connections. You can change -p to map the container's port somewhere else.

Development

Installation

Basic setup:

uv sync --extra dev

With the basic setup, you can use uv run tox to run tests and check code style.

Recommended setup:

uv sync --extra dev --extra tests --extra integtests --extra codestyle

With the recommended setup, packages for testing and code style checking will be installed which allows IDEs like VsCode or Cursor to check the code or run tests during development.

Integration tests

To run integration tests locally, use uv run tox -e integtests. NOTE: You will need to set the following environment variables:

INTEGTEST_STORAGE_API_URL
INTEGTEST_STORAGE_TOKEN
INTEGTEST_WORKSPACE_SCHEMA

In order to get these values, you need a dedicated Keboola project for integration tests.

Updating `uv.lock`

Update the uv.lock file if you have added or removed dependencies. Also consider updating the lock with newer dependency versions when creating a release (uv lock --upgrade).

Updating Tool Documentation

When you make changes to any tool descriptions (docstrings in tool functions), you must regenerate the TOOLS.md documentation file to reflect these changes:

uv run python -m src.keboola_mcp_server.generate_tool_docs
