TDengine Query MCP Server

A Model Context Protocol (MCP) server that provides read-only TDengine database queries for AI assistants. Execute queries, explore database structures, and investigate your data directly from your AI-powered tools.

Supported AI Tools

This MCP server works with any tool that supports the Model Context Protocol, including:

• Cursor IDE: Set up in .cursor/mcp.json
• Anthropic Claude: Use with a compatible MCP client
• Other MCP-compatible AI assistants: Follow the tool’s MCP configuration instructions

Features & Limitations

What It Does

• ✅ Execute read-only TDengine queries (SELECT, SHOW, DESCRIBE only)
• ✅ Provide database/stable information and metadata
• ✅ List available database and stables

What It Doesn’t Do

• ❌ Execute write operations (INSERT, UPDATE, DELETE, CREATE, ALTER, etc.)
• ❌ Provide database design or schema generation capabilities
• ❌ Function as a full database management tool

This tool is designed specifically for data investigation and exploration through read-only queries. It is not intended for database administration, schema management, or data modification.

How to use

Run from source code

The recommended way to use this MCP server is to run it directly with uv without installation. This is how both Claude Desktop and Cursor are configured to use it in the examples below.

If you want to clone the repository:

git clone https://github.com/Abeautifulsnow/tdengine-mcp.git
cd tdengine-mcp

Then you can run the server directly:

uv run src/tdengine_mcp_server -th 192.100.8.22 -db log -ll debug

Alternatively you can change the .env file in the src/tdengine_mcp_server/ directory to set the environment variables and run the server with the following command:

uv run src/tdengine_mcp_server

Important: the .env file will have higher priority than the command line arguments.

Install From Pypi by pip command

# Install globally with pip
pip install tdengine_mcp_server

and then run:

python -m tdengine_mcp_server -h

Install by uvx command

uvx tdengine-mcp-server -h

Install From smithery by npx command

npx -y @smithery/cli@latest install @Abeautifulsnow/tdengine-mcp --client cursor --config '"{}"'

You can change the client after the --client option with alternatives claude, ‘windsurf’ and so on. Also you can refer to this: smithery/tdengine-mcp-server
