Ask Claude About Your Home Network — Free & Local

Bottom line: EdgeDefense MCP is a free, open-source MCP server that lets Claude (or Cursor, 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

Two steps: install the server once, then add it to whichever client you use.

1. Install the server

Requires Python 3.10+.

pip install "edgedefense-core @ git+https://github.com/splashxmoon/edgemcp.git#subdirectory=core-engine" "edgedefense-mcp @ git+https://github.com/splashxmoon/edgemcp.git#subdirectory=mcp-server"

2. Add it to your client

Cursor and VS Code install directly. Claude Code and Claude Desktop don't support one-click install yet, so those buttons copy what you need instead.

Try It

Paste one of these after installing.

"Scan my home network and tell me what's connected."

"What's my network trust score, and why?"

"Is anything unusual connected right now?"

Tools

edgedefense_scan_network Discovers what's currently connected and summarizes it in plain language. Start here.

edgedefense_list_devices Lists what's connected — filter to just the unknown ones, or just the ones with problems.

edgedefense_get_device_detail Everything known about one device: what it probably is, who made it, what it's running.

edgedefense_get_trust_score A single 0–100 score for your network, with the reasons behind it.

edgedefense_explain_finding Turns 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.
