> Read-only MCP server for OpenSearch and OpenSearch Dashboards — search, aggregate, and explore your log data from Claude Code or any MCP-compatible AI assistant.

## Features

- **17 tools** covering connectivity checks, index/field discovery, full-text search, aggregations, time-series histograms, numeric stats, PPL queries, index settings, document explain, comparative analysis, and a generic GET escape hatch
- **3 investigation prompts** — reusable templates for common log analysis workflows (single-agent investigation, top-offenders sweep, baseline comparison)
- **Parallel requests** — all tools support concurrent execution; Claude Code can fire multiple queries in a single turn (e.g. `opensearch_count` + `opensearch_terms` + `opensearch_search` simultaneously) for faster investigations
- Two backends: OpenSearch Dashboards proxy (preferred) or direct OpenSearch REST API
- Hard limits on search result size (default 200) and histogram bucket count (default 2,000) to protect cluster health
- Text field aggregation warnings (fielddata heap pressure)
- No-time-range warnings on potentially expensive full-history queries
- Read-only write guard — only safe endpoints are in the allowlist
- Configurable via environment variables or `~/.config/mcp-o…
