It provides:\n\n- **48 specialized debugging tools** with rich descriptions and usage context\n- **Dynamic MCP resources** that expose live session state (`rr://sessions/{id}`)\n- **Concurrent replay sessions** for debugging different processes simultaneously\n- **Full reverse execution** — step, continue, and finish in both directions\n- **Multi-process support** — debug exec'd processes (`pid`) or forked-without-exec children (`fork_pid`)\n- **Conditional and temporary breakpoints**, watchpoints, and catchpoints (throw/catch/syscall/signal)\n\n**New to rr debugging?** See [RR_DEBUGGING_GUIDE.md](RR_DEBUGGING_GUIDE.md) for concepts, workflows, and best practices.\n\n## Requirements\n\n- Linux (rr only runs on Linux)\n- Python 3.11+\n- [rr](https://rr-project.org/) installed and in PATH\n- An rr recording to debug\n\n## Installation\n\n### Claude Code\n\n```bash\nclaude mcp add rr-mcp -- uvx rr-mcp\n```\n\n### Other MCP clients\n\nAny MCP client that supports stdio servers can run `uvx rr-mcp` (or `pipx run rr-mcp`).\n\n### Installing from source\n\n**For development** (recommended - no reinstall needed after changes):\n\n```bash\ngit clone https://github.com/jnjaeschke/rr-mcp && cd rr-mcp\nuv sync  # Install dependencies\n\n# Configure Claude Code to run from source\nclaude mcp add rr-mcp -- uv run --directory /absolute/path/to/rr-mcp rr-mcp\n```\n\n**For production use**:\n\n```bash\ngit clone https://github.com/jnjaeschke/rr-mcp && cd rr-mcp\nuv tool install .\n\n# Configure Claude Code\nclaude mcp add rr-mcp -- rr-mcp\n```\n\nFor other MCP clients, use the appropriate command (`uv run ...` for development or `rr-mcp` for production).\n\n## Usage\n\nOnce installed, the server loads automatically when you start your MCP client.
