Ask Claude About Your Home Network, Free & Local

• BY ARUN DASS

Bottom line: EdgeDefense MCP is a free, open-source MCP server that lets Claude (or any MCP client) answer plain-English questions about your home network, what's connected, what an unknown device probably is, and whether anything looks wrong. It runs entirely on your machine: no account, no cloud, no admin rights, nothing uploaded.

Install

Select your client to get the install command.

claude mcp add edgedefense -- edgedefense-mcp

Run in any terminal. Restart Claude Code and the tools are available.

Try It

Paste one of these after installing.

"Scan my home network and tell me what's connected."
"What's new on my network since yesterday?"
"What's my network trust score, and why?"
"Is anything unusual connected right now?"
"Name the device at 192.168.86.44 'Main Device 1'."
"Check my local security posture."
Tools
edgedefense_scan_networkDiscovers what's currently connected and summarizes it in plain language. Start here.
edgedefense_whats_changedTells you what's new on your network, what vanished, and what ports opened since last scan.
edgedefense_list_devicesLists what's connected, filter to just the unknown ones, or just the ones with problems.
edgedefense_get_device_detailEverything known about one device: what it probably is, who made it, what it's running.
edgedefense_name_deviceAssigns a friendly name to a device so you can track it.
edgedefense_local_securityChecks the Wi-Fi security, DNS, and open ports on the machine running the server.
edgedefense_get_trust_scoreA single 0–100 score for your network, with the reasons behind it.
edgedefense_explain_findingTurns any flagged issue into a plain-English explanation of what it means and what to do.

Two more tools exist but are switched off until you explicitly enable them, since they need administrator access: deeper traffic analysis that watches network activity for a set number of seconds and always asks for consent first.

How It's Built
Nothing phones home

No outbound request, ever, not even analytics. Vendor lookups read a bundled local database.

Zero permissions by default

Discovery and scoring run as a normal user. Deeper traffic analysis is opt-in, with a clear prompt first.

Read-only, on purpose

No tool can change anything on your network. This version looks, it doesn't act.

Open source, always

MIT licensed. Read exactly what it does before you run it on your home network.

How This Relates to EdgeDefenseAI

EdgeDefense MCP covers zero-permission device discovery and identification, enough to answer “what's on my network and is it safe.” The paid EdgeDefenseAI appliance goes further: it runs continuously, uses trained ML to catch behavior a one-off scan can't, and can actually isolate a compromised device. The MCP tool and the appliance share the same open-source discovery engine, but the ML detection pipeline behind the paid product isn't in the free repo, that's a standing decision, not a limitation waiting to be lifted.

Frequently Asked Questions

Is EdgeDefense MCP really free? Yes. It's a free, open-source MCP server under the MIT license. There's no account, no subscription, and no cloud dependency, it runs entirely on your machine.

Does EdgeDefense MCP send my network data anywhere? No. It runs entirely locally with zero data egress. There's no outbound network request in the code, not even for analytics, and vendor lookups read a bundled local database instead of calling an API.

What's the difference between EdgeDefense MCP and the paid EdgeDefenseAI appliance? EdgeDefense MCP covers zero-permission device discovery and identification. The paid appliance goes further: it runs continuously, uses trained ML to catch behavior a one-off scan can't, and can actually isolate a compromised device.
