ClaudeR - RStudio MCP Server

ClaudeR - The Modern Researcher's Toolkit Connect a live R or Python session, in RStudio or Positron, to Claude Code, Codex, or any MCP-based LLM agent. For interactive analysis, multi-agent orchestration, and automated manuscript auditing. It runs locally over stdio via the published package.

People who work with codex, data science and gemini and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

      "command": "uvx",
      "args": [
        "clauder-mcp"
      ]
    }

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package clauder-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.IMNMV is GitHub-verified and matches the repo owner
