Keboola MCP Server

What is Keboola MCP Server about?

Keboola MCP Server connects AI assistants (Claude, Cursor, Windsurf, VS Code, etc.) directly to a Keboola project. It turns Keboola features—storage tables, component configs, SQL transformations, jobs, flows, and documentation—into callable tools that agents can invoke without writing glue code.

How to use Keboola MCP Server?

1. Remote option – enable the hosted Remote MCP Server from the Keboola project settings and configure the AI client with the provided SSE URL. Authentication is handled via OAuth.
2. Local option – clone the repository, install Python 3.10+, set the required Keboola environment variables (KBC_STORAGE_TOKEN, KBC_STORAGE_API_URL, KBC_WORKSPACE_SCHEMA, optional KBC_BRANCH_ID), and start the server with uvx keboola_mcp_server --transport <transport> (e.g., streamable-http or sse).
3. Docker option – run the official Docker image, passing the same environment variables and selecting a transport.
4. Configure the AI client (Claude, Cursor, etc.) to point to the server (remote URL or local host) and the client will automatically launch or connect to the server.

Key features of Keboola MCP Server

• Storage tools: list buckets/tables, query tables, update descriptions.
• Component tools: create, list, inspect, and modify extractors, writers, data apps, and transformation configs.
• SQL tools: generate and run SQL transformations from natural‑language prompts.
• Job tools: start component or transformation jobs and fetch execution details.
• Flow tools: create, update, and manage Conditional Flows and Orchestrator Flows.
• Data Apps: create, deploy, and manage Streamlit Data Apps.
• Documentation tools: search and update project documentation and metadata.
• Development branches: scope all operations to a specified Keboola branch via KBC_BRANCH_ID or X-Branch-Id header.
• Multiple transports: stdio, streamable-http, sse (deprecated), http-compat.

Use cases of Keboola MCP Server

• Self‑service data exploration: an AI assistant can answer “What tables contain customer data?” by querying the storage layer.
• Automated pipeline generation: generate SQL transformations or orchestrator flows from plain English specifications.
• Job orchestration via chat: start extraction or transformation jobs and monitor their status without leaving the AI chat UI.
• Documentation querying: ask the assistant to retrieve or update project documentation directly.
• Branch‑isolated development: developers can experiment with new pipelines in a development branch while the production environment remains untouched.

FAQ for Keboola MCP Server

Q: Do I need to run the server myself when using Claude or Cursor? A: No. In Integrated Mode the client automatically starts the server using the configured command.

Q: Which transport should I choose? A: Use streamable-http for bidirectional communication over HTTP. stdio is fine for single‑client local use.

Q: How do I authenticate? A: Provide a valid Keboola Storage API token (KBC_STORAGE_TOKEN). For remote servers OAuth is used; for local servers set the env variable or send it in request headers.

Q: Can I limit the server’s access? A: Yes. Use a limited storage token instead of the master token and optionally restrict the workspace schema.

Q: How do I work with development branches? A: Set KBC_BRANCH_ID globally or include the X-Branch-Id header in each request. The server will scope all operations to that branch.

Q: Is Docker supported? A: Yes. Pull keboola/mcp-server:latest and run it with the required environment variables.

🚀 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

1. Get your remote server URL: Navigate to your Keboola Project Settings → MCP Server tab
2. Copy the server URL: It will look like https://mcp.<YOUR_REGION>.keboola.com/sse
3. Configure your AI assistant: Paste the URL into your AI assistant's MCP settings
4. 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
• Windsurf: Configure with the remote server URL
• Make: Configure with the remote server URL
• Other MCP clients: Configure with the remote server URL

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.

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

Claude Desktop Configuration

1. 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)
2. Add the following configuration:
3. 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

1. Go to Settings → MCP
2. Click "+ Add new global MCP Server"
3. 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:

1. Clone the repository and set up a local environment
2. 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
