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.

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Executes code built at runtime clauder-py/src/clauder/server.py:210
                exec(compile(code, "<clauder>", "exec"), STATE.namespace)

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.

ClaudeR - RStudio MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for ClaudeR - RStudio MCP Server?
ClaudeR - RStudio MCP Server 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 clauder-mcp was installed 1 733 times last week.
How do I connect ClaudeR - RStudio MCP Server?
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 clauder-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use ClaudeR - RStudio MCP Server?
The pypi package clauder-mcp was installed 1 733 times in the last week. Week over week that is +12%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is ClaudeR - RStudio MCP Server open source?
We cannot say either way: written in Python, 361 stars on GitHub and 17 open issues, but we could not determine the licence, and without one the code is not open source by default.
