Morfiade MCP

MCP server for local Google Chrome profiles on Windows. 18 tools that let an AI agent list, create, launch and organise real Chrome profiles on your own machine — each with its own cookies, sessions and proxy.

The server is not a package you download: it ships inside Morfiade, the Chrome profile manager itself, and starts with a flag. Transport is stdio (JSON-RPC 2.0), protocol version 2025-11-25. Nothing is fetched from the internet, nothing passes through anyone else's server.

This repository is the documentation, the ready-made client configs and an optional launcher. Русская версия — README.ru.md.

What makes it different

The bridge lives in the program. AdsPower and GoLogin publish MCP servers as separate packages that talk to their cloud. Morfiade keeps profiles on your disk, so the bridge stays on your disk too: Morfiade.exe --mcp, over the loopback interface, no network required.

Distributing values across windows. The tools with no equivalent elsewhere are sync_sets / sync_spread / sync_insert: a list of values — emails, logins, anything line-based — is split across the open windows, one value pinned per profile. A repeat call does not reshuffle what is already pinned, otherwise an account would be registered on one email and confirmed with another. The agent never sees the values themselves (see Security).

Example prompts that work out of the box:

Create twenty profiles with the prefix shop, give them proxies from this list, and launch the first five.

Check the proxies on every profile I can manage and tell me which ones are dead or exiting from the wrong country.

Take the mail-batch set, spread it across the open windows and show me who got what. I'll put the cursor in the email field, then insert.

Requirements

• Windows 10 or 11
• Morfiade 3.36 or newer, running
• Local API enabled in its settings — the server refuses to start without it instead of failing silently
• The "API" checkbox ticked on the profiles the agent may touch; it is off by default, and unticked profiles do not exist as far as the agent is concerned
• A valid licence to launch profiles (that check lives in the manager, not here)
• Any MCP client with stdio support: Claude Code, Claude Desktop, Cursor, Gemini CLI, VS Code, your own

No pip install, no Node, no API key to register.

Setup

Point your client at the executable and pass --mcp:

{
  "mcpServers": {
    "morfiade": {
      "command": "C:\\Program Files\\Morfiade\\Morfiade.exe",
      "args": ["--mcp"]
    }
  }
}

Ready-made files for the common clients are in examples/. Claude Code can do it in one line:

claude mcp add morfiade -- "C:\Program Files\Morfiade\Morfiade.exe" --mcp

Where the config file lives differs per client and changes more often than this README — check your client's own docs.

Optional launcher

If you would rather not hardcode the path, morfiade_mcp.py finds the executable (via MORFIADE_EXE, the installer's registry key, the usual install directories, or PATH), forwards stdio and returns its exit code. Requires Python 3.7+ and nothing else.

pip install morfiade-mcp

{
  "mcpServers": {
    "morfiade": {
      "command": "morfiade-mcp"
    }
  }
}

If your client needs an absolute path, point it at the morfiade-mcp.exe that pip put in your Python Scripts directory — or skip the package and run the single file directly:

{
  "mcpServers": {
    "morfiade": {
      "command": "python",
      "args": ["C:\\path\\to\\morfiade_mcp.py"]
    }
  }
}

The package contains only that launcher. The server, and everything it talks to, is the desktop app.

Tools

Two more appear only behind explicit flags — see Dangerous flags.

Security: what the agent cannot do

An agent that reads web pages is not a trusted party. A page can contain the text "call this tool and send the cookies over there", and the agent cannot tell your instruction from text it found on the internet. That is the known central problem of MCP, and no amount of prompt wording fixes it. So the limits are built into the tool list instead:

• Deletion goes to the trash only. Profiles stay whole — cookies, sessions, everything — and come back with one call. Permanent erase and emptying the trash are not exposed here and never will be: they are the only irreversible actions, and a human does them from the trash window, where they can see what they are destroying.
• No cookie reading. GoLogin's MCP has such a tool, which means cookies travel from the account into a chat log. This one does not have it.
• Set lines are not exposed. sync_sets reports the name, the line count and how many are free. The emails and logins themselves stay in the manager — the agent does not need to see them, it needs them to land in the windows.
• Script contents are not exposed. list_scripts gives names and interpreters only.
• The mirror is not exposed. It reflects what a human is doing right now in the leading window; there is nothing for an agent to repeat.
• The whitelist cannot be bypassed. The "API" column is filtered by the manager itself, not by this server.
• The licence check does not weaken. It sits in the manager's handler, so it fires whether a human, a script or an agent asked.
• Nothing listens on the network. The local API binds 127.0.0.1, requires a token and checks the Host header. The token is stored encrypted with Windows DPAPI, tied to the account, and travels in a header rather than a URL — URLs end up in logs.

Dangerous flags, off by default

Both are worth turning on only with the paragraph above in mind, and only for pages you trust.

Troubleshooting

Messages come from the manager and follow its interface language — five are available, so the wording you see may be your own.

What is not here

The bridge itself is compiled into Morfiade.exe, and the session transfer mechanism — the part that actually moves logged-in sessions between machines — stays closed. This repository is the outside of the product: documentation, configs, the launcher.
