Analyzing logs with 14 specialized tools

🤔 Why?

Without log-analyzer-mcp	With log-analyzer-mcp
Copy-paste chunks of logs	Point Claude at the file
Lose context between pastes	Full file access
Manual format parsing	Auto-detection
Miss related errors	Smart correlation

✨ Features

Auto-Detection — Identifies format from 9+ common log types
Smart Search — Pattern matching with context, regex, and time filtering
Error Extraction — Groups similar errors, captures stack traces
Natural Language — Ask questions like "what errors happened today?"
Sensitive Data Scan — Detect PII, credentials, and secrets
Multi-File Analysis — Correlate events across distributed systems
Streaming — Handles 1GB+ files without memory issues

🚀 Quick Start

# Install (adds to Claude Code automatically)
uvx codesdevs-log-analyzer install

Then in Claude Code:

Analyze /var/log/app.log and tell me what's causing the errors

📦 Installation

One-liner (Recommended)
