What is R-Server MCP?
R-Server MCP is a specialized Model Context Protocol server that enables AI models to generate data visualizations using R's ggplot2 library and execute arbitrary R scripts. It exposes two tools (render_ggplot and execute_r_script) and is intended for developers integrating R capabilities into MCP-powered applications.
How to use R-Server MCP?
Configure the server in an MCP client's settings file, specifying either the local binary path or using the Docker startup script with the --docker flag. The server communicates via stdio transport and requires Go 1.22+, R 4.0+ with ggplot2, and optionally Docker for containerized execution.
Key features of R-Server MCP
- ggplot2 Rendering: Generate visualizations from R code containing ggplot2 commands.
- R Script Execution: Run any R script and return its text output.
- Output Formats: Supports PNG, JPEG, PDF, and SVG.
- Customization: Control image dimensions and resolution.
- Error Handling: Clear messages for invalid R code or rendering failures.
- Docker Integration: Isolated container execution for security and dependency management.
Use cases of R-Server MCP
- Generate statistical charts (scatter plots, bar charts, etc.) from AI-generated R ggplot2 code.
- Execute R scripts for data cleaning, analysis, or modeling and return textual results.
- Embed R-based data visualization in MCP-powered chat or assistant workflows.
- Run R code in a secure, containerized environment without exposing the host system.
