Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account Samrj12 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Doppel is a local MCP server that lets an AI assistant drive your real, already logged-in Chrome or Edge browser over CDP.

What you can do: Connect an assistant to your real Chrome or Edge browser session over the Chrome DevTools Protocol.
Work inside a browser profile that is already logged in, rather than a fresh automated instance.
The manifest lists no individual tools, so the exact actions available are not documented in the supplied material.
When to use it: Useful when an assistant needs to act in a browser where you are already signed in, such as sites behind a login, and you want it to work in your everyday browser instead of a separate automation profile.
Requirements: Runs as a local process on the user's machine, installed from the npm package doppel-mcp over stdio. Desktop only; no web executable. A local Chrome or Edge installation with a logged-in profile is implied by the description. No environment variables, headers or authentication are declared.

Before you install

The assistant operates your real, logged-in browser session, so it can reach any account and data that profile is signed into. No tool list is provided, so what it can read, submit, change or delete is not documented; review the package before granting access.

Installation

In SourceWeft

Open Doppel in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Tools

SourceWeft has not started this package in its sandbox yet, so its tools are not known.
