RR

About

RR is an MCP (Model Context Protocol) server designed to provide a robust interface for controlling and interacting with Mozilla's rr debugger. It empowers AI assistants and other MCP clients to programmatically manage rr replay sessions, execute GDB/rr commands, and analyze execution traces. Built on a RESTful HTTP interface and utilizing the GDB Machine Interface (MI) protocol, RR facilitates advanced debugging workflows such as automated debugging, crash analysis in CI/CD pipelines, and remote debugging of recorded failures.

Key Features

• GDB Command Execution: Run arbitrary GDB/rr commands during replay sessions
• HTTP Interface: RESTful API for remote debugging control
• Replay Management: Start and manage rr replay sessions for recorded execution traces
• Session Management: Automatic cleanup when switching between traces
• 0 GitHub stars
• Async Communication: Robust async handling of GDB Machine Interface (MI) protocol

Use Cases

• Automated Debugging: Let AI assistants help debug recorded failures
• Remote Debugging: Debug production recordings without manual GDB interaction
• Crash Analysis: Programmatically analyze crashes in CI/CD pipelines
