You want to check later what Claude Code did while you left it working
Each request becomes one line: which MCP it used, whether it read outside sites, ran commands and wrote files. Click one to see that work's connections map and timeline.
AI ACTIVITY MAP
What your AI went through
and what it touched, at a glance.
See the work you handed to Claude Code as one flow per request (Claude Code → MCP → read outside sites → ran commands → wrote files) and as a connections map: AI → MCP server → tool → touched. Viewing it is free, and the records stay on this PC.
We don't stop your AI. We only brake when something is risky.
01 / WHEN
SCENES
When it protects you.
You want to know whether an unknown MCP server slipped in
Each MCP server gets a label: Started by your AI, or Started from outside / unknown. Outside or unknown ones are drawn with a dashed line and ⚠, so they stand out in the map too.
Did it run a command right after reading outside text?
The classic prompt-injection pattern is: read outside text, then run or send what it says. NEXORIA counts boundary crossings such as Outside site → local file first, and shows each site read by its landing host and the number of instruction-like lines.

04 / HOW
MECHANISM
How it works.
What you see
Boundary crossings (outside site → local file, secret → sent out, outside / unknown → MCP, writes / deletes outside the work folder), a story for each request, the connections map, recent calls and a timeline. ▲ marks where secrets, outside text and sending out all came together.
Where the data comes from, and which AI
It uses the records AI Brake keeps through Claude Code's hooks, plus PC Watch's records of MCP servers starting. Right now it records Claude Code with the NEXORIA hook installed.
What it never shows
Paths, file names, URLs and command contents are never shown (only kinds and counts). For outside sites it keeps only the landing host and a summary (language, length, number of instruction-like lines). Excerpts of text read are kept for 14 days only if you turn that setting on (off by default).
05 / DATA
PRIVACY
What goes out,
what stays in.
What is sent out
- Nothing. The records and the map stay on this PC
What is never sent
- Paths, file names, URLs and command contents
- Excerpts of text read (kept on this PC for 14 days only if you turn the setting on)
06 / LIMITS
HONEST
What it can do,
and what it can't.
What it can do
- See, per request, the MCP servers the AI went through and what it did
- See AI → MCP server → tool → touched as a map
- Mark MCP servers started from outside / unknown
- See how many outside sites were read, their landing hosts and instruction-like lines
- Viewing AI Activity is free
What it can't do / limits
- This screen is for looking. Stopping actions is AI Brake's job
- Only work by Claude Code with the NEXORIA hook installed is recorded
- Telling who started an MCP server needs PC Watch records (starting PC Watch needs a plan or the free trial; without records it shows No start record)

08 / FAQ
QUESTIONS
Frequently asked questions
Where do I find it?+
In the app, open AI guard → AI activity on the left. It is built from the records when you open the screen, so nothing keeps running in the background.
Does it cost anything?+
Viewing AI Activity is free. Starting PC Watch, which is used to tell who started an MCP server, needs a plan or the free trial.
Does it record what the work contained?+
No. Only the kind of action, how many times, and the judgement. Paths, file names, URLs and command contents never appear on screen or in the records.
