Open-source Observability 2.0 database for metrics, logs, and traces with an official MCP server for AI-assisted data querying.
GreptimeDB is an open-source, cloud-native time-series database built for the Observability 2.0 era, unifying metrics, logs, and traces into a single data model and serving as a complete OpenTelemetry backend. It positions itself as a replacement for running Prometheus, Loki, and Elasticsearch as separate systems — instead providing one database that handles all three signal types with consistent query semantics and shared storage.
The GreptimeDB MCP Server is a particularly compelling feature for the AI agent ecosystem. It enables AI assistants and agents to securely access and manage GreptimeDB through structured MCP primitives — listing tables, reading data, and executing queries via SQL, TQL (PromQL-compatible), and RANGE queries. Built-in security features include read-only enforcement and data masking, ensuring AI agents can analyze observability data without risk of data modification or exposure. The server has been primarily developed for Claude Desktop but works with any MCP-compliant client.
