Common questions

Is Druid MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: DRUID_ROUTER_URL, DRUID_AUTH_PASSWORD

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

Druid MCP Server

A comprehensive Model Context Protocol (MCP) server for Apache Druid that provides extensive tools, resources, and prompts for managing and analyzing Druid clusters.

*Developed by iunera - Advanced AI and Data Analytics Solutions*

Overview

This MCP server implements a intend-based architecture where profiles picture their usaae intend and the corresponding area of Druid usage. The server provides three main types of MCP components:

Tools - Executable functions for performing operations
Resources - Data providers for accessing information
Prompts - AI-assisted guidance templates

Video Walkthrough

Learn how to integrate AI agents with Apache Druid using the MCP server. This tutorial demonstrates time series data exploration, statistical analysis, and data ingestion using natural language with AI assistants like Claude, ChatGPT, and Gemini.

🌊 Y̊pipe: AI-Powered UI for Druid

Experience your data like never before with [Y̊pipe (formerly Data-Philter)](https://ypipe.com), a local desktop application that makes offline AI practical, designed by iunera. It leverages this Druid MCP Server to provide a seamless, conversational interface for your Druid cluster.

Natural Language Queries: Ask questions in plain English and get results instantly.
Local & Secure: Runs completely locally with support for offline models (CPU/GPU).
Plug & Play: Works out-of-the-box with the Development Druid Installation.

📋 Ypipe Integration Blueprint

For seamless integration, we provide a predefined Ypipe integration blueprint file:

Blueprint File: druid.ypipe
Configuration Guide: Ypipe Example Documentation

This blueprint allows you to easily connect and configure the Druid MCP server in Ypipe through a visual workspace.

Ypipe Workspace Flow	Druid Node Configuration

MCP Inspector Interface

When connected to an MCP client, you can inspect the available tools, resources, and prompts through the MCP inspector interface:

Available Tools

The tools interface shows all available Druid management functions organized by feature areas including data management, ingestion management, and monitoring & health.

Available Resources

The resources interface displays all accessible Druid data sources and metadata that can be retrieved through the MCP protocol.

Available Prompts

The prompts interface shows all AI-assisted guidance templates available for various Druid management tasks and data analysis workflows.

Quick Start

MCP Configuration for LLMs

A ready-to-use MCP configuration file is provided at mcp-servers-config.json that can be used with LLM clients to connect to this Druid MCP server.

Examples

The configuration includes multiple integration and transport options:

STDIO (default): see examples/stdio/README.md - server is spawned by the MCP client over STDIO.
Streamable HTTP (profile: http): see examples/streamable-http/README.md - single /mcp endpoint per MCP 2025-06-18.
Ypipe Blueprint: see examples/ypipe/README.md - configure and run the Druid MCP Server inside the Ypipe desktop client using the druid.ypipe blueprint.

Docker examples using environment variables:

# STDIO mode (default)

docker run --rm -i \ -e DRUID_ROUTER_URL=http://your-druid-router:8888 \ -e DRUID_COORDINATOR_URL=http://your-druid-coordinator:8081 \ iunera/druid-mcp-server:latest

HTTP mode (enable profile 'http' and expose /mcp)

docker run -p 8080:8080 \ -e SPRING_PROFILES_ACTIVE=http,query \ -e DRUID_ROUTER_URL=http://your-druid-router:8888 \ -e DRUID_COORDINATOR_URL=http://your-druid-coordinator:8081 \ iunera/druid-mcp-server:latest

Note on Spring profiles:

Default profile: stdio,query
HTTP profile: set SPRING_PROFILES_ACTIVE=http,query to enable Streamable HTTP at /mcp

Prerequisites

Java 25
Maven 3.6+
Apache Druid cluster running with router on port 8888

Build and Run

# Build the application

mvn clean package -DskipTests

Run the application

java -jar target/druid-mcp-server-2.0.1.jar

The server will start on port 8080 by default.

For detailed build instructions, testing, Docker setup, and development guidelines, see development.md.

Security & Authentication

Streamable HTTP and SSE transports are secured with OAuth 2.0 by default.
Clients must send a valid Bearer token in the Authorization header when connecting.
Example: Authorization: Bearer YOUR_JWT_TOKEN

Environment Variables

DRUID_MCP_SECURITY_OAUTH2_ENABLED:
Description: Enables or disables OAuth2 security for client authentication.
Type: Boolean
Default: true (OAuth2 is enabled by default as per the text above)
Usage: Set to false to disable OAuth2 authentication. When disabled, clients can access the server without providing OAuth2 tokens.
For enterprise SSO integration (OpenID Connect, Azure AD, Keycloak, etc.), please send an inquiry to consulting@iunera.com and see Contact & Support.

Installation from Maven Central

If you prefer to use the pre-built JAR without building from source, you can download and run it directly from Maven Central.

Prerequisites

Java 25 JRE only

Download and Run

Download the JAR from Maven Central https://repo.maven.apache.org/maven2/com/iunera/druid-mcp-server/

# STDIO mode (default)
