๐ก Example Usage
Ask Claude to use the log reader tool:
Can you check my MCP logs for any connection errors in the last day?Or with specific parameters:
Can you look through MCP logs with filter="error" and lines=50 to find initialization issues?โ๏ธ How It Works
1. The server automatically detects your OS and finds the appropriate log directory
2. It locates all MCP log files and sorts them by modification time (newest first)
3. The requested page of log files is retrieved based on pagination settings
4. Files are processed with size limits to prevent overwhelming responses
5. Filtered content is returned in a structured format with pagination details
