IoTDB MCP Server

Overview

A Model Context Protocol (MCP) server implementation that provides database interaction and business intelligence capabilities through IoTDB. This server enables running SQL queries.

Components

Resources

The server doesn't expose any resources.

Prompts

The server doesn't provide any prompts.

Tools

The server offers different tools for IoTDB Tree Model and Table Model. You can choose between them by setting the “IOTDB_SQL_DIALECT” configuration to either “tree” or “table”.

Tree Model

• metadata_query
  • Execute SHOW/COUNT queries to read metadata from the database
  • Input:
    • query_sql (string): The SHOW/COUNT SQL query to execute
  • Returns: Query results as array of objects
• select_query
  • Execute SELECT queries to read data from the database
  • Input:
    • query_sql (string): The SELECT SQL query to execute
  • Returns: Query results as array of objects

Table Model

Query Tools

• read_query
  • Execute SELECT queries to read data from the database
  • Input:
    • query (string): The SELECT SQL query to execute
  • Returns: Query results as array of objects

Schema Tools

• list_tables

  • Get a list of all tables in the database
  • No input required
  • Returns: Array of table names

• describe-table

  • View schema information for a specific table
  • Input:
    • table_name (string): Name of table to describe
  • Returns: Array of column definitions with names and types

Claude Desktop Integration

Prerequisites

• Python with uv package manager
• IoTDB installation
• MCP server dependencies

Development

# Clone the repository
git clone https://github.com/apache/iotdb-mcp-server.git
cd iotdb_mcp_server

# Create virtual environment
uv venv
source venv/bin/activate  # or `venv\Scripts\activate` on Windows

# Install development dependencies
uv sync

Configure the MCP server in Claude Desktop's configuration file:

MacOS

Location: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows

Location: %APPDATA%/Claude/claude_desktop_config.json

You may need to put the full path to the uv executable in the command field. You can get this by running which uv on MacOS/Linux or where uv on Windows.
