A Model Context Protocol server for comprehensive network packet capture and analysis using Wireshark/tshark
Server has 10 tools with consistent naming (verb_noun pattern) and basic descriptions. All tools have input schemas with typed parameters and descriptions. However, descriptions are generic (avg ~60 chars, well below the 194-char baseline for A+ tools), lack context on WHEN to use each tool, and omit recovery guidance. No output schemas documented. Parameter descriptions are minimal. Missing error handling patterns, confirmation steps for destructive operations (start/stop capture), and field-level guidance. Tools are well-composed (single responsibility) but lack the depth needed for confident LLM selection.
Analyze network performance metrics from pcap file
Analyze a pcap file and generate insights
Extract HTTP requests from pcap file
Generate traffic timeline with specified time intervals
Get status of all active capture sessions
List all captured pcap files in storage directory
List available network interfaces for packet capture
Descriptions are too brief (avg 60 chars vs 194-char baseline). Most lack context on WHEN to use the tool, prerequisites, or what distinguishes it from similar tools. E.g., 'Analyze a pcap file and generate insights' does not explain when to call analyze_pcap_file vs extract_http_requests vs analyze_network_performance.
No output schemas documented. LLMs cannot plan downstream calls or extract required fields. E.g., does list_captured_files return file paths, sizes, timestamps? Does analyze_pcap_file return a summary string or structured protocol breakdown?

Search for specific patterns in packet content
Start packet capture on specified interface
Stop an active packet capture session
Destructive operations (start_packet_capture, stop_packet_capture) lack confirmation or dry-run support. An agent could accidentally stop an active capture or overwrite files without safeguards.
No error handling guidance. Tools do not document what errors are retryable, user-fixable, or fatal. E.g., if start_packet_capture fails because the interface is busy, should the agent retry or ask the user to stop other captures?
Parameter descriptions lack format/constraint guidance. E.g., 'capture_filter' says 'BPF filter' but does not explain valid syntax, common patterns, or what happens if the filter is invalid. 'time_interval' lacks min/max bounds.
