Control a real Chrome browser to complete any task: fill forms, extract data, book flights.
Nothing to run from here
Hronaut Browser 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
Control visible, persistent Hronaut browser workspaces through a local MCP connection.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http hronaut-browser-mcp http://127.0.0.1:47812/mcp
# 2 — ask your agent for something these tools do
# browser_status, browser_show, browser_request_user_attention and 63 more
The address is on your own machine or network: it answers only once you start the server there, the way its own source says, and a hosted client cannot reach it.
Hronaut Browser costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one answers at an address on your own machine: you start Hronaut Browser yourself, the way its own source says, and your client connects to it there — with your files and your network in its reach. Its scan result is on the Security tab.

This is a public server: you run it yourself and this marketplace is not in the path. The address is on your own machine or network: it answers only once you start the server there, the way its own source says, and a hosted client cannot reach it. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, read from the address; if the publisher says otherwise, swap that one word.
claude mcp add --scope user --transport http hronaut-browser-mcp http://127.0.0.1:47812/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at an address on your own machine: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing at an address on your own machine, where you start the server yourself — this marketplace is not in the path, and the server runs with your file system and your network.

ATrust score 95 / 100
Release 2.4.29 · scanned 6 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.

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.
Tool surfacenot available
Implementation sourceread
Package metadataread
Live transportnot available
No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".
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. moderate is the level these add up to.

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.

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 Hronaut Browser 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.
