What's required to get started with RR?

Users need Python 3.12+, the Mozilla rr debugger installed and available in PATH, and pre-recorded execution traces created using the `rr record` command.

What is RR (rr-mcp-server)?

RR (rr-mcp-server) is an MCP server offering programmatic control for Mozilla's rr debugger. It enables automated replay of execution traces and GDB command execution through a RESTful HTTP API.

What are the primary use cases for RR?

It's ideal for automated debugging with AI assistants, crash analysis in CI/CD pipelines, debugging flaky tests, and remote debugging of production recordings without manual GDB interaction.

What debugging tasks can RR automate?

RR can automate starting and managing rr replay sessions, executing arbitrary GDB/rr commands, and provides robust asynchronous handling for GDB's Machine Interface protocol.

Enables programmatic control and interaction with Mozilla's rr debugger for replay sessions via an MCP server.

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.

主要功能

01GDB Command Execution: Run arbitrary GDB/rr commands during replay sessions

02HTTP Interface: RESTful API for remote debugging control

03Replay Management: Start and manage rr replay sessions for recorded execution traces

04Session Management: Automatic cleanup when switching between traces
