karellen-rr-mcp is a plugin bundle for AI coding tools published by karellen. Marketplaces we read that list it: 1 (Claude Code: claude-plugins-community). We first saw it on 2026-10-11 and have recorded no change since. As of our marketplace pass on 2026-10-12.

In its own words, on Claude Code: claude-plugins-community:

Claude Code plugin for rr reverse debugging via MCP. Automatically configures the karellen-rr-mcp MCP server and includes a crash detection hook that suggests rr when a command exits with a signal (SIGSEGV, SIGABRT, etc.) or sanitizer output is detected, a debugging skill with the full record-replay-analyze workflow, and an rr-investigator agent for autonomous crash investigation through reverse execution. Requires Linux x86-64 with rr, gdb, and pip install karellen-rr-mcp.

Is this your plugin?

Add it to your projects and prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.

Data comes from the public marketplace file https://github.com/anthropics/claude-plugins-community/blob/HEAD/.claude-plugin/marketplace.json. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
