How to Set Up and Use Groundhog
Groundhog is an educational MCP server and coding assistant built in Rust that teaches developers how AI coding agents like Cursor, Goose, and Aider work from first principles. Rather than being a production tool, it is a transparent, inspectable system designed to demystify the internals of agentic coding assistants — how they read files, plan changes, and execute shell commands. By understanding Groundhog's mechanics, developers can drive production coding tools more effectively or build their own agents.
Prerequisites
- Rust toolchain installed (rustup recommended) for building from source
- An MCP-compatible client such as Claude Desktop or Cursor
- Git for cloning the repository
- Basic familiarity with how MCP servers work is helpful but not required
Clone the Repository
Clone the Groundhog repository from GitHub to your local machine.
git clone https://github.com/ghuntley/groundhog.git
cd groundhogBuild from Source with Cargo
Build the Groundhog binary using the Rust Cargo build system. This produces a release-optimized binary in the target/release directory.
cargo build --release
# The binary will be at:
./target/release/groundhogExplore the explain Command
Groundhog's primary teaching tool is the explain command, which shows you exactly what a coding agent would do at each step — reading files, constructing context, and deciding on actions.
./target/release/groundhog explainConfigure as an MCP Server
Add Groundhog to your Claude Desktop configuration to use it as an MCP server. Point the command to the compiled binary.
{
"mcpServers": {
"groundhog": {
"command": "/path/to/groundhog/target/release/groundhog",
"args": ["--transport", "stdio"]
}
}
}Study the Internals
Use Groundhog's built-in logging and telemetry to observe what the agent does at each turn. The project is designed to be read alongside its source code so you understand the mechanisms behind AI coding assistants.
# Run with verbose logging to see internal operations
./target/release/groundhog --verbose explainGroundhog Examples
Client configuration
Claude Desktop configuration for Groundhog using the locally compiled binary.

"args": ["--transport", "stdio"]
}
}
}Prompts to try
Example interactions that showcase Groundhog's educational purpose — understanding agent internals.
- "Explain how you would approach reading and summarizing a large codebase"
- "Walk me through what happens when a coding agent receives a task to refactor a function"
- "Show me how you construct your context window when working on a file"
- "What tools does a coding agent typically need to complete a programming task?"Troubleshooting Groundhog
Cargo build fails with missing dependencies
Ensure your Rust toolchain is up to date by running 'rustup update stable'. Check that all system dependencies are installed — on Ubuntu/Debian, run 'apt-get install build-essential'. On macOS, ensure Xcode Command Line Tools are installed with 'xcode-select --install'.
Binary not found after build
The compiled binary is located at target/release/groundhog after a release build, or target/debug/groundhog after a debug build (cargo build without --release). Use an absolute path in the MCP client configuration.
Claude Desktop does not show Groundhog tools
Verify the binary path in claude_desktop_config.json is absolute and the file has execute permissions (chmod +x ./target/release/groundhog on macOS/Linux). Fully restart Claude Desktop after saving the configuration.
