GreptimeDB MCP Server
Official
by GreptimeTeam
# greptimedb-mcp-server
A Model Context Protocol (MCP) server implementation for [GreptimeDB](https://github.com/GreptimeTeam/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:
```bash
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
# Usage
