### Description (declared)

# loki-tail-mcp

An [MCP](https://modelcontextprotocol.io) server for
[Grafana Loki](https://grafana.com/oss/loki/), designed around how LLMs
actually query logs: compact output, hard row caps, and a
**fuzzy container-name rescue** that turns the classic
empty-result-because-wrong-name failure into an auto-corrected retry or
an actionable suggestion list. Built on the
[Python MCP SDK](https://github.com/modelcontextprotocol/python-sdk)
(FastMCP); runs as a local stdio server or a containerized Streamable
HTTP service with bearer auth.

## Tools

| Tool | Notes |
|---|---|
| `loki_tail_container` | "What is service X saying?" — the primary tool. Accepts approximate names: service vocabulary (`vpn`, `proxy`), bare names (`sonarr`), typos. On zero results it distinguishes *valid-but-quiet* from *unknown name*, auto-substitutes a unique fuzzy match (flagged in the output), or suggests candidates. |
| `loki_query_range` | Raw LogQL range query — multi-container correlation (`{container=~"a\|b"} \|= "..."`) and metric queries (`count_over_time(...)`). |
| `loki_query_instant` | Instant query at a point in time (metric queries). |
| `loki_list_containers` | Durable container names (ephemeral CI/batch names hidden). |
| `loki_list_labels` / `loki_list_label_values` | Raw label discovery. |
| `loki_patterns` | Log pattern mining — thousands of lines → ranked recurring templates with counts. Requires the server-side [pattern ingester](https://grafana.com/docs/loki/latest/operations/query-patterns/) (`pattern_ingester.enabled: true`). |
| `loki_log_volume` | Rank containers by log bytes over a window — "which service suddenly got noisy". |
| `loki_detected_fields` | Fields Loki can auto-extract from a stream (name/type/cardinality/parser) — discover `\| logfmt \| status>=500` opportunities before writing LogQL. |

### The name-resolution design

Matching always runs against **live label values**, never a hardcoded
list, so it survives renames. Resolution tries, in order: exac…
