greptimedb-mcp-server is an MCP server implementation for GreptimeDB that enables AI assistants to securely and structurally explore and analyze databases. It exposes MCP capabilities to interact with a GreptimeDB instance, including listing resources (tables), reading resource data, listing and using tools, and executing SQL via a controlled interface. Supported operations include list_resources to enumerate tables, read_resource to fetch table data, list_tools to discover available tools, call_tool to run SQL, and prompts-related operations (list_prompts, get_prompt) to tailor agent behavior. The project is described as experimental and under active development; data security and privacy considerations are not specifically addressed in the README, so users should exercise caution. Configuration supports connecting to GreptimeDB via environment variables (GREPTIMEDB_HOST, GREPTIMEDB_PORT with a default of 4002 for MySQL protocol, GREPTIMEDB_USER, GREPTIMEDB_PASSWORD, GREPTIMEDB_DATABASE, GREPTIMEDB_TIMEZONE) or CLI arguments. The server can be integrated with Claude Desktop by adding an MCP server entry that invokes uv to run the greptimedb_mcp_server.server module. The project is MIT licensed and provides development guidance, including installation steps, testing, and debugging tools like MCP Inspector.
