greptimedb-mcp-server

A Model Context Protocol (MCP) server implementation for GreptimeDB.

This server provides AI assistants with a secure and structured way to explore and analyze databases. It enables them to list tables, read data, and execute SQL queries through a controlled interface, ensuring responsible database access.

Capabilities

• list_resources to list tables
• read_resource to read table data
• list_tools to list tools
• call_tool to execute an SQL
• list_prompts to list prompts
• get_prompt to get the prompt by name

Installation

pip install greptimedb-mcp-server

Configuration

Set the following environment variables:

GREPTIMEDB_HOST=localhost    # Database host
GREPTIMEDB_PORT=4002         # Optional: Database port (defaults to 4002 if not specified)
GREPTIMEDB_USER=root
GREPTIMEDB_PASSWORD=
GREPTIMEDB_DATABASE=public

Or via command-line args:

• --host the database host
• --port the database port
• --user the database username
• --password the database password
• --database the database name
