What Loki Mcp Server does

An MCP server for querying Grafana Loki directly with a discovery-first workflow — labels, values, series, and LogQL queries without requiring Grafana.

Test This Server

No automated test available for this server. Check the GitHub README for setup instructions.

README

Loki MCP Server

Query Grafana Loki logs directly from AI agents using the Model Context Protocol (MCP).

Built in Go. Enables AI-powered log analysis using LogQL.

Supports integration with:

Claude Desktop
AI agent frameworks
automation tools
DevOps workflows

Motivation

The official grafana/loki-mcp exposes a single loki_query tool, which means the LLM must already know valid label names and values before it can build a query. This project takes a different approach by providing 5 granular tools — labels, label_values, and series let the LLM discover what's available in Loki first, then construct precise query_range or query calls. The result is more accurate log retrieval with fewer wasted round-trips.

Additionally, this server enforces strict input validation (limit caps, direction validation, label name format checks, mutually exclusive auth) to surface errors early instead of forwarding bad requests to Loki.

Features

query_range — Execute LogQL range queries to fetch logs over a time window
query — Execute LogQL instant queries for point-in-time evaluation
labels — List all available label names
label_values — List values for a specific label
series — Find active log stream series matching a selector

Installation

Homebrew

brew install incu6us/tap/loki-mcp-server

Go install

go install github.com/incu6us/loki-mcp-server/cmd/loki-mcp-server@latest

Or build from source:

git clone https://github.com/incu6us/loki-mcp-server.git
cd loki-mcp
go build -o loki-mcp-server ./cmd/loki-mcp-server

Configuration

The server is configured entirely via environment variables, injected by the MCP client.

Variable	Required	Default	Description
`LOKI_URL`	yes	—	Base URL of the Loki instance
`LOKI_USERNAME`	no	—	Basic auth username
`LOKI_PASSWORD`	no	—	Basic auth password
`LOKI_BEARER_TOKEN`	no	—	Bearer token authentication
`LOKI_TLS_SKIP_VERIFY`	no	`false`	Skip TLS certificate verification
`LOKI_TENANT_ID`	no	—	`X-Scope-OrgID` header for multi-tenant deployments
`LOKI_HTTP_TIMEOUT`	no	`30s`	HTTP request timeout (Go duration, e.g. `10s`, `1m`)

Note: Basic auth (LOKI_USERNAME/LOKI_PASSWORD) and bearer token (LOKI_BEARER_TOKEN) are mutually exclusive.

Usage with Claude Code

Add to your Claude Code MCP configuration (~/.claude.json):
