What is Kusto MCP Server?

Kusto MCP Server is a middleware service that acts as a bridge between users and Azure Data Explorer clusters. It provides functions such as data querying and table structure viewing through a standardized protocol, simplifying the interaction process with ADX clusters.

How to use Kusto MCP Server?

After configuring the Claude Desktop client to connect to the MCP server, you can perform operations such as data querying and table structure viewing. The server supports two authentication methods: Azure AD authentication is used in the production environment, while no authentication is required for the local emulator.

Applicable scenarios

Suitable for analysts and developers who need to frequently query ADX cluster data, especially in scenarios where ADX query capabilities need to be integrated into other applications.

Main features

Table list query
Provides three types of table list query functions: list queries for internal tables, external tables, and materialized views.
Data query
Supports executing Kusto Query Language (KQL) queries on internal tables/materialized views and external tables.
Table structure viewing
Can retrieve detailed structure information for any internal table, external table, or materialized view.
Advantages
Unified interface to access ADX clusters, simplifying development
Supports both production environment and local emulator modes
Provides a complete set of functions for table structure and data querying
Limitations
Requires pre - configuration of ADX cluster connection information
Azure AD application registration and permission configuration are required in the production environment
Only supports Kusto Query Language (KQL)

How to use

Configure Claude Desktop
Edit the claude_desktop_config.json file and add the Kusto MCP server configuration.
Start the MCP server
Start the server by running the mcp - server - kusto module through uvicorn.
Execute a query
Send query commands through the client tool to obtain data or table structure information.

Usage examples

Data exploration
Analysts need to know which data tables are available in the ADX cluster
Data query
Developers need to query data from a specific table in the last 7 days
Table structure inspection
Data engineers need to know the field structure of a table to write an ETL process
