Tooltrail

A personal audit log of every tool your AI agents call

Which agent, which tool, what data flowed where — journalled by hand or parsed straight out of a pasted MCP log, then scored so you can see how far your data actually travelled. Free, offline, nothing leaves this browser.

What you can do in Tooltrail on the web

1

Journal any tool call

Agent, tool name, what flowed where, destination, date — plus a direction (read, search, write, execute, send, delete) and a data class (public through credentials).

2

Paste an MCP log and it parses

JSON objects, key=value traces and plain 'agent · tool — summary' lines all become dated entries, with the direction and data class guessed from the tool name.

3

Exposure scoring

Every call scores how far the data went times how much that data matters — 1 for reading something public, 25 for deleting credentials — banded low, watch, high, critical.

4

Per-agent accountability

See which agent racked up the most exposure, which tools it reached for, what data classes it touched and how much of it left your device.

5

Filters that matter

Unreviewed, left the device, high exposure, by agent, or free-text across tool, summary and destination.

6

Export the trail

Download the whole audit log as CSV — date, agent, tool, direction, class, destination and exposure — or a full JSON backup.

Questions

Is the web version of Tooltrail free?+

Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.

Where is my data stored?+

Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.

Do I need an account?+

You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.

How is the web version different from the Tooltrail iPhone app?+

Nothing hooks into your agents: this is a journal you fill in or paste into, not a live interceptor. MCP has no consumer audit hook to subscribe to yet. The parser guesses direction and data class from the tool name and text — always worth correcting on the entry screen. Exposure scoring is Tooltrail's own heuristic (how far the data went × how sensitive it was), not an industry standard. The iPhone app keeps the same log on-device; the web version keeps it in this browser only, so the two do not sync.
