What is this?

An MCP server that wraps tshark (and optional Wireshark suite tools) into a structured analysis interface. Works with Claude Desktop, Claude Code, Cursor, VS Code, and 18+ other MCP clients.

You:    "Find all DNS queries going to suspicious domains in this capture."
Claude: [calls wireshark_extract_dns_queries → wireshark_d

Questions

What is the Wireshark MCP server?

Wireshark-MCP,Give your AI assistant a packet analyzer. Drop a .pcap file, ask questions in plain English — get answers backed by real tshark data.

What tools does Wireshark expose?

34 in total: 29 read-only, 4 that write, and 1 that can delete or overwrite (wireshark_editcap_deduplicate). Every one is listed on this page with its risk.

Is Wireshark safe to connect to an agent?

With care. The audit graded it B (84/100) and found 18 things worth knowing before you trust this server, listed below with the exact line each was found on. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does Wireshark need?

No credential environment variables were found in its source, so it appears to need none.

How does Wireshark run?

It speaks sse, stdio and streamable-http, so it runs as a local process your client starts. It is published on PyPI as wireshark-mcp.

How current is this page?

The grade is for one exact copy of the source (b3e58482df43), read on 2026-10-06. The repository is watched and re-audited when it changes.
