Roo MCP Installer

Description

A command-line utility designed to streamline the installation and management of Roo Model Context Protocol (MCP) servers. It fetches MCP server code from Git repositories, handles dependencies, configuration, and registration within the Roo environment.

Features

• Git Repository Installation: Installs MCPs directly from GitHub repository URLs (e.g., https://github.com/user/repo.git) or shorthand slugs (user/repo).
• Subdirectory Support: Allows installation from a specific subdirectory within a repository using a colon separator (e.g., user/repo:subdir).
• Installation Scopes: Supports both global (shared across projects, typically in ~/.roo/mcps) and project (specific to the current directory, in ./.roo/mcps) installation scopes.
• Automatic Project Type Detection: Identifies project types based on standard configuration files:
  • Node.js (package.json)
  • Python (requirements.txt, pyproject.toml)
  • Go (go.mod, main.go)
  • Rust (Cargo.toml) (Still in progress) (may not work)
• Dependency Management: Automatically installs project dependencies using the detected package manager:
  • npm install (with fallback checks for yarn install or pnpm install)
  • pip install -r requirements.txt (with fallback check for pip3)
  • poetry install (with fallback check for pip install -e .)
  • go mod download
  • cargo build (also serves as dependency fetching)
• Build Step Execution: Automatically runs build commands if necessary:
  • Go: go build -o <output_path> <target>
  • Node.js: npm run build (or yarn/pnpm) if a build script exists and seems necessary based on main/bin fields.
• Environment Variable Configuration:
  • Detects required environment variables by checking mcp.json (highest priority), .env.example, or JSON code blocks within the repository's README.md file.
  • Interactively prompts the user to enter values for detected variables.
  • Masks input for variables with names suggesting sensitivity (e.g., containing KEY, SECRET, TOKEN, PASSWORD).
  • Allows skipping the interactive configuration using the --skip-env flag.
• Automatic Tool Checking & Installation:
  • Checks for the presence of essential command-line tools (git, npm, node, python, go, cargo, bun, tsc, etc.).
  • Prompts the user to automatically install missing tools globally if a known installation command exists (e.g., npm install -g bun).
• List Installed MCPs: The list command displays all MCPs installed in both global and project scopes, showing their names and installation paths.
• Log Viewing: The logs command allows viewing the application's log files.
  • --lines / -n: Show only the last N lines.
  • --follow / -f: Continuously monitor the log file for new entries (similar to tail -f).
• Rich TUI: Utilizes the rich library to provide an enhanced terminal user interface with spinners, progress bars, styled text, tables, and interactive prompts.
• Debug Mode: The --debug flag enables verbose logging to the console and log files for troubleshooting.
• Demo Mode: The --demo flag (for the install command) simulates the installation process, showing the UI and intended actions without actually modifying the file system or running commands.

Usage

The script is run using python roo.py <command> [options].

Commands:

• install <repo_input> [options]
  • Installs or updates an MCP server.
  • <repo_input>: The repository URL, user/repo slug, or user/repo:subdir.
  • --scope <global|project>: Set the installation scope (default: global).
  • --skip-env: Skip interactive prompt for environment variables.
  • --demo: Run installation in demo mode (no actual changes).
  • --debug: Enable debug logging.
• list [options]
  • Lists installed MCP servers.
  • --debug: Enable debug logging.
• logs [options]
  • Shows log files.
  • --lines N or -n N: Show the last N lines.
  • --follow or -f: Follow log output in real-time.
  • --debug: Enable debug logging.

Examples

Install an MCP globally:

python roo.py install username/my-cool-mcp

Install an MCP into the current project:

python roo.py install https://github.com/username/project-specific-mcp.git --scope project

Install an MCP from a subdirectory, skipping environment variable setup:

python roo.py install username/mono-repo:tools/my-mcp --skip-env

Simulate an installation with debug output:

python roo.py install username/test-mcp --demo --debug

List all installed MCPs:

python roo.py list

View the latest log entries:

python roo.py logs

View the last 100 lines of the logs:

python roo.py logs --lines 100

Follow the logs in real-time:

python roo.py logs --follow

Dependencies

• Python: Version 3.11 or higher is required (due to the use of tomllib).
• Git: Must be installed and accessible in the system's PATH.
• Third-Party Python Packages: See requirements.txt below. Specific project types may require additional tools (like Node.js/npm, Go, Rust/Cargo) to be installed.
