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.

Features

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
Metadata: Search, read, and update project documentation and object metadata using natural language

Preparations

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.

Before setting up the MCP server, you need three key pieces of information:

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

Keboola Region

Your Keboola 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`

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",
        "--api-url", "https://connection.YOUR_REGION.keboola.com"
      ],
      "env": {
        "KBC_STORAGE_TOKEN": "your_keboola_storage_token",
        "KBC_WORKSPACE_SCHEMA": "your_workspace_schema"
      }
    }
  }
}

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",
        "--api-url", "https://connection.YOUR_REGION.keboola.com"
      ],
      "env": {
        "KBC_STORAGE_TOKEN": "your_keboola_storage_token",
        "KBC_WORKSPACE_SCHEMA": "your_workspace_schema"
      }
    }
  }
}

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_TOKEN=your_keboola_storage_token &&",
          "export KBC_WORKSPACE_SCHEMA=your_workspace_schema &&",
          "/snap/bin/uvx -m keboola_mcp_server.cli",
          "--api-url https://connection.YOUR_REGION.keboola.com",
          "'"
      ]
    },
  }
}

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.cli",
        "--transport", "stdio",
        "--api-url", "https://connection.YOUR_REGION.keboola.com"
      ],
      "env": {
        "KBC_STORAGE_TOKEN": "your_keboola_storage_token",
        "KBC_WORKSPACE_SCHEMA": "your_workspace_schema",

      }
    }
  }
}

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_TOKEN=your_keboola_storage_token
export KBC_WORKSPACE_SCHEMA=your_workspace_schema

# Run with uvx (no installation needed)
uvx keboola_mcp_server --api-url https://connection.YOUR_REGION.keboola.com

# OR, if developing locally
python -m keboola_mcp_server.cli --api-url https://connection.YOUR_REGION.keboola.com

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.

Option D: Using Docker

docker pull keboola/mcp-server:latest

docker run -it \
  -e KBC_STORAGE_TOKEN="YOUR_KEBOOLA_STORAGE_TOKEN" \
  -e KBC_WORKSPACE_SCHEMA="YOUR_WORKSPACE_SCHEMA" \
  keboola/mcp-server:latest \
  --api-url https://connection.YOUR_REGION.keboola.com

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).
