About this project

iterm-mcp is a Model Context Protocol server designed to enhance command execution within your iTerm sessions. With features like efficient token use and natural integration, it allows seamless interactions between the model and the terminal environment, providing full control and REPL support while minimizing dependencies.

iterm-mcp is a Model Context Protocol (MCP) server designed to seamlessly provide command execution capabilities within the active iTerm session. This tool enhances productivity by enabling intelligent interaction between users and their terminal environment.

Key Features

Efficient Token Use: iterm-mcp enables the model to focus on the output that matters most, typically the last few lines from long-running commands, improving efficiency during your workflows.
Natural Integration: The server allows users to interact directly with the iTerm interface. Users can query the current terminal screen or assign tasks to the model, observing its execution in real-time.
Full Terminal Control and REPL Support: Users can leverage the model’s ability to launch and interact with Read-Eval-Print Loops (REPLs), as well as send control characters like ctrl-c and ctrl-z for comprehensive terminal control.
Minimal Dependencies: With a lightweight design, iterm-mcp is straightforward to incorporate into environments such as Claude Desktop and other MCP clients using simple command line operations.

Safety Considerations

Users are encouraged to engage with this tool responsibly, as iterm-mcp does not enforce command safety evaluations. It is essential to keep an eye on the model’s actions, especially during multi-step operations, and to start with smaller tasks to become familiar with its behavior.

Toolset

The following tools are included to facilitate command execution and interaction with the terminal:

write_to_terminal: Executes commands within the active iTerm terminal and returns the output line count.
read_terminal_output: Retrieves a specified number of lines from the output of the active terminal.
send_control_character: Sends control characters to the terminal for enhanced interaction.

Requirements

iTerm2 must be actively running.
Node.js version 18 or higher is required for operation.

Development Tools

For those looking to extend or modify the functionality,

Install dependencies using: yarn install
Build with: yarn run build
For auto-rebuild during development, use: yarn run watch

For debugging, the MCP Inspector can be employed to streamline the process:

yarn run inspector
yarn debug <command>

This Inspector provides a URL for accessing debugging tools via a web browser.

Overall, iterm-mcp presents a refined solution for accessing terminal commands, enhancing the user experience with intuitive features and a focus on streamlined command management.
