OpenObserve MCP Server

An MCP (Model Context Protocol) server that enables AI assistants to query and explore your OpenObserve observability data. This server provides read-only access to logs, metrics, and traces stored in OpenObserve, allowing LLMs to help you analyze and troubleshoot your systems.

assistant: The available streams are:
- **suricata** (Type: logs, Doc count: ~13.5 million)

assistant: I found 2 hosts sending journald events (stream: journald):

- franz-OptiPlex-7050 — 1,960 events — last_seen _timestamp = 1771082221716601 (μs since epoch)
- asus-pn50 — 1,268 events — last_seen _timestamp = 1771082221680679 (μs since epoch)

Query used:
SELECT host_name, COUNT(*) AS cnt, MAX(_timestamp) AS last_seen FROM journald GROUP BY host_name ORDER BY cnt DESC LIMIT 200;

Would you like me to:
- convert the last_seen timestamps to human-readable datetimes, or
- list more hosts, or
- show recent journald messages per host?
