# @rog0x/mcp-log-tools
Log analysis and processing tools for AI agents, exposed via the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/).
## Tools
### parse_logs
Parse log content in common formats: JSON logs, Apache/Nginx access logs, syslog, and structured logs. Supports custom regex patterns with named capture groups. Extracts timestamp, level, message, source, and additional structured fields.
### filter_logs
Filter parsed log entries by:
- Log level (ERROR, WARN, INFO, DEBUG)
- Date range (ISO 8601)
- Keyword search (case-insensitive)
- Regex pattern matching
- Source/logger name
Returns matched entries along with level occurrence counts.
### analyze_logs
Analyze log patterns to surface operational insights:
- Top 10 most frequent errors (normalized)
- Error rate over time (hourly buckets)
- Request volume per hour
- Slowest endpoints (from HTTP access logs)
- Anomaly detection (sudden spikes or drops using standard deviation)
### format_logs
Convert between log formats and produce reports:
- JSON to plain text, plain to JSON, CSV, or table
- ANSI colorization by log level
- Structured field extraction
- Summary report generation
### log_stats
Compute comprehensive log statistics:
- Total and non-empty line counts
- Level distribution with percentages
- Date range coverage
- Unique IP addresses and request counts
- Top user agents
- HTTP status code distribution
- Throughput (entries per second)
## Setup
```bash
npm install
npm run build
```
## Usage with Claude Desktop
Add to your `claude_desktop_config.json`:
```json
{
"mcpServers": {
"log-tools": {
"command": "node",
"args": ["path/to/mcp-log-tools/dist/index.js"]
}
}
}
```
## Supported Log Formats
| Format | Example |
|--------|---------|
| JSON | `{"timestamp":"2024-01-15T10:30:00Z","level":"ERROR","message":"Connection failed"}` |
| Apache/Nginx | `127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET /index.html HTTP/1.1" 200 2326` |
| Syslog | `Jan 1 00:00:00 hostname process[1234]: Something happened` |
| Structured | `2024-01-15T10:30:00.000Z [ERROR] [ModuleName] Something failed` |
| Custom | Any format using a regex with named capture groups |
