pip install -r requirements.txt

Quick Start

1. Initialize Configuration

rstudio-mcp --init-config

This creates a default configuration file at ~/.rstudio-mcp/config.yaml.

Edit the configuration file to customize settings:

nano ~/.rstudio-mcp/config.yaml

3. Run the Server

# Run with default configuration
rstudio-mcp

# Run with custom configuration
rstudio-mcp --config /path/to/config.yaml

# Run in debug mode
rstudio-mcp --debug

Configuration

The server uses YAML configuration files. Here's an example configuration:

Integration with AI Coding Assistants

This MCP server is designed to work seamlessly with popular AI coding assistants in RStudio's terminal environment. The server supports the Model Context Protocol (MCP) specification and can be integrated with various AI clients.

Supported AI Clients

Based on the MCP client compatibility matrix, the following AI coding assistants support MCP integration:

• Claude Code - Supports prompts and tools
• VS Code GitHub Copilot - Full MCP support with dynamic tool discovery
• Continue - Supports tools, prompts, and resources
• Cursor - Supports tools via Composer
• Cline - Supports tools and resources
• JetBrains AI Assistant - Supports tools for all JetBrains IDEs

Configuration for AI Assistants

1. Claude Code Integration

Claude Code can connect to this MCP server to enhance R development workflows:

{
  "mcpServers": {
    "rstudio-mcp": {
      "command": "rstudio-mcp",
      "args": ["--config", "~/.rstudio-mcp/config.yaml"],
      "env": {
        "RSTUDIO_MCP_DEBUG": "false"
      }
    }
  }
}

2. VS Code GitHub Copilot

Configure in VS Code settings or workspace settings:

{
  "github.copilot.chat.mcp.servers": {
    "rstudio-mcp": {
      "command": "rstudio-mcp",
      "args": ["--stdio"],
      "env": {
        "RSTUDIO_MCP_CONFIG": "~/.rstudio-mcp/config.yaml"
      }
    }
  }
}

3. Continue Extension

Add to your Continue configuration (~/.continue/config.json):

{
  "mcpServers": [
    {
      "name": "rstudio-mcp",
      "command": "rstudio-mcp",
      "args": ["--stdio"],
      "env": {
        "RSTUDIO_MCP_CONFIG": "~/.rstudio-mcp/config.yaml"
      }
    }
  ]
}

4. RStudio Terminal Integration

To use with AI assistants directly in RStudio's terminal:

1. Start the MCP server in the background:

   # In RStudio Terminal
   rstudio-mcp --daemon --port 3000
   

2. Configure your AI assistant to connect via SSE:

   # Server endpoint for SSE connections
   http://localhost:3000/sse
   

3. Available tools in RStudio context:

   • create_environment - Create R environments
   • execute_r_code - Run R code with result capture
   • create_project - Create RStudio projects
   • install_package - Manage R packages
   • get_project_info - Access project metadata

Environment Variables

Set these environment variables for optimal integration:

# RStudio MCP Configuration
export RSTUDIO_MCP_CONFIG="~/.rstudio-mcp/config.yaml"
export RSTUDIO_MCP_LOG_LEVEL="INFO"
export RSTUDIO_MCP_PORT="3000"

# R Environment
export R_HOME="/usr/local/lib/R"
export R_LIBS_USER="~/.rstudio-mcp/libraries"

Usage Examples

With Claude Code in RStudio Terminal

# Start MCP server
rstudio-mcp --daemon

# Claude Code can now:
# - Create R environments: "Create a new R environment for data analysis"
# - Execute R code: "Run this statistical analysis and show results"
# - Manage projects: "Set up a new RStudio project for machine learning"

With GitHub Copilot in VS Code

# In VS Code terminal connected to RStudio server
# Copilot can access:
# - R workspace objects via rstudio-workspace:// resources
# - Project files via rstudio-project:// resources
# - Environment info via rstudio-environment:// resources
# - Generated plots via rstudio-plot:// resources

Troubleshooting

1. Connection Issues:

   # Check if MCP server is running
   rstudio-mcp --status
   
   # Test connection
   curl http://localhost:3000/health
   

2. Permission Issues:

   # Ensure proper permissions
   chmod +x $(which rstudio-mcp)
   chown -R $USER ~/.rstudio-mcp/
   

3. R Environment Issues:

   # Verify R installation
   rstudio-mcp --check-r
   
   # Reset environments
   rstudio-mcp --reset-environments
