Kitsune MCP Server

by junyeong-nero Your server? Claim it
local only

Kitsune runs on your own machine — the client starts it, so there is no endpoint to ping. 1 092 installs a week from pypi. Last commit 2 Nov 2026.

Let your coding agent use the Firefox, Zen, or LibreWolf browser you already have open.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Executes code built at runtime extension/content/content.js:2796
      const result = eval(code);

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add kitsune -- uvx kitsune-browser-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "kitsune": {

Optional settings from the registry entry, left out of the block above: KITSUNE_MODE (Task surface and per-request policy: read, draft, or act), KITSUNE_CAPS (Comma-separated capability groups to enable; all enables every group except storage and history), KITSUNE_PUBLISH (Groups listed when a session starts; other enabled tools stay reachable through the gateway tools), KITSUNE_ASK_BEFORE_ACT (Set to 1 to hold submits, payment pages, JavaScript, and cookie access until the call is confirmed).

Kitsune — questions

Answers built from our own checks of this server.

Why is there no uptime for Kitsune?
Kitsune runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package kitsune-browser-mcp was installed 1 092 times last week.
How do I connect Kitsune?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls kitsune-browser-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use Kitsune?
The pypi package kitsune-browser-mcp was installed 1 092 times in the last week. Week over week that is -65%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Kitsune open source?
Yes — it is published under the MIT licence, written in Python, 12 stars on GitHub and 10 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
