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.

File ships in the package but is absent from the source [пакет] src/mcp_server_researchtwin/__init__.py:1, [пакет] src/mcp_server_researchtwin/__main__.py:1, [пакет] src/mcp_server_researchtwin/server.py:1

        panel.innerHTML = html;

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 researchtwin -- uvx mcp-server-researchtwin
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "researchtwin": {
      "args": [
        "mcp-server-researchtwin"
      ],
      "command": "uvx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.researchtwin]
command = "uvx"
args = ["mcp-server-researchtwin"]
.cursor/mcp.json
{
  "mcpServers": {
    "researchtwin": {
      "args": [
        "mcp-server-researchtwin"
      ],
      "command": "uvx"
    }
  }

    }
  }
}

This one needs environment variables set before it will start: RESEARCHTWIN_URL (Base URL for ResearchTwin API (default: https://researchtwin.net)). The author declared them in the registry entry; get the values from the project itself.

ResearchTwin — questions

Answers built from our own checks of this server.

Why is there no uptime for ResearchTwin?
ResearchTwin 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 mcp-server-researchtwin was installed 63 times last week.
How do I connect ResearchTwin?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls mcp-server-researchtwin straight from pypi; nothing to host, nothing to sign up for.
How many people use ResearchTwin?
The pypi package mcp-server-researchtwin was installed 63 times in the last week. Week over week that is -10%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is ResearchTwin open source?
We cannot say either way: written in TeX, 1 stars on GitHub and 4 open issues, but we could not determine the licence, and without one the code is not open source by default.
