Control a real Chrome browser to complete any task: fill forms, extract data, book flights.
Nothing to run from here
Flintrail is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Drive a real Chrome live, record a flow once, replay it in milliseconds without an LLM.
Quickstart
Install it the way its author documents:
1. Download flintrail.mcpb and open it in Claude Desktop or another client that installs MCP bundles (.mcpb)
2. Its sha256 is fa576058086607914d32d55eabd80871f8f332968a34fcd67f5b3ae7e566b44d

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Flintrail as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.

Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Open a URL in a background tab of the dedicated browser (logged-in sessions kept). Returns a compact snapshot whose [eN] refs can be used directly in fl_act.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| url | string | yes | — |
Take control of a tab the user already has open in the browser (first match on a URL substring), e.g. a site they just signed in to by hand. Returns its snapshot.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| url | string | yes | Substring of the tab URL |
Run SEVERAL actions in one call (fill a whole form, click, submit, wait, extract) and get one fresh snapshot back. Always batch as many actions as possible: one call beats ten.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tab | string | yes | — |
| actions | array | yes | — |
| snapshot | boolean | no | — |
Re-read a tab: interactive elements with refs, headings and the start of the text.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tab | string | yes | — |
Run JavaScript in the page and return the result. Fastest way to pull tables, lists or links.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tab | string | yes | — |
| js | string | yes | Function body with return, e.g. return [...document.querySelectorAll("tr")].map(r => r.innerText) |
List the API calls (fetch/XHR) the site made, with method, status, timing, body and a JSON sample. Use it to replace UI clicks with a direct {do:"request"} step: the fastest possible replay.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| filter | string | no | Substring the URL must contain. |
| limit | number | no | — |
Console errors and uncaught exceptions of a tab (level "all" adds warnings and logs). fl_act and fl_snapshot already say when new errors appeared.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tab | string | yes | — |
| level | string | no | — |
| clear | boolean | no | — |
Screenshot of a tab, or of one element with ref / selector. Only when the visual layout matters: snapshots are much cheaper. Pixels are CSS pixels, usable as x / y for {do:"mouse"}.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tab | string | yes | — |
| full | boolean | no | — |
| ref | string | no | — |
| selector | string | no | — |
List tabs opened by Flintrail.
No parameter schema on file.
Close a Flintrail tab.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tab | string | yes | — |
Start recording a flow. Every fl_open / fl_act after this is captured with robust element fingerprints so fl_run can replay it without an LLM. repairFrom keeps steps before that index and replaces the rest.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | — |
| description | string | no | — |
| startUrl | string | no | — |
| repairFrom | number | no | — |
Stop recording and save the flow (save=false to discard).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| save | boolean | no | — |
Replay a recorded flow at browser speed, no LLM. On failure (site changed) it stops at the failing step and returns the page so the flow can be repaired.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | — |
| vars | object | no | — |
| tab | string | no | — |
Replay the same flow for many variable sets in parallel, each in its own background tab.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | — |
| runs | array | yes | — |
| concurrency | number | no | — |
| keepTabs | boolean | no | — |
List recorded flows with their variables and last timing.
No parameter schema on file.
Show a flow with all its steps and element fingerprints.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | — |
Turn the literal value of one step into a variable {{var}}, e.g. after recording by demonstration.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | — |
| step | number | yes | Step index, as shown by fl_flow (0-based). |
| var | string | yes | — |
Status of the Flintrail browser extension (extension mode).
No parameter schema on file.

ATrust score 93 / 100
Release 1.3.0 · scanned 30 Oct 2026
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | high | capability blast radius (high) — client exposure if the model is manipulated | −6 |

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

Live transportnot available
Tools were statically extracted from the published source (19 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
1 of the 19 recovered tools are registered only when config.passwordSources.length holds (src/server.ts:74) — typically when a key or option is configured. They are part of the server's surface and were analysed; a server started without that configuration exposes only the other 18.
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. high is the level these add up to.
18 tools are registered unconditionally · 1 more only when config.passwordSources.length holds (src/server.ts:74) — typically when a key or option is configured. All 19 are in the table below and were analysed; the conditional ones are marked.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
It installs from its repository rather than from a versioned package, so the command cannot be pinned to a release. The history below is for reading; the current release on file is 1.3.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Flintrail can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
