Instead of iteratively adding debug output and rebuilding, the LLM can\nrecord a failing test with rr, then replay it with full forward and reverse debugging via\nGDB/MI, inspecting program state without modifying source code.\n\n## Requirements\n\n- **Linux** on x86-64 (rr only supports Linux; aarch64 is experimental)\n- **[rr](https://rr-project.org/)** installed and on PATH\n- **[GDB](https://www.sourceware.org/gdb/)** installed and on PATH (used by rr for debugging)\n- **Python** >= 3.11\n- **`perf_event_paranoid`** set to `1` to allow recording:\n  ```bas…","publisher":{"name":"Karellen, Inc.","url":null},"homepage":"https://github.com/karellen/karellen-rr-mcp","repository":"https://github.com/karellen/karellen-rr-mcp/issues","version":"0.3.1","license":"Apache-2.0","protocols":["mcp"],"tags":["rr","reverse-debugging","gdb","mcp","model-context-protocol"],"pricing":null,"endpoints":[{"url":"pypi:karellen-rr-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","license":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"code.debugging","name":"Debugging","confidence":1,"provenance":"derived"}],"categories":["code"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"karellen-rr-mcp","registry":"pypi","observedAt":"2026-11-03T10:25:09.681Z","publishedAt":"2026-10-11T00:21:43.700520Z","latestVersion":"0.3.1"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"karellen-rr-mcp","url":"https://pypi.org/project/karellen-rr-mcp/","firstSeenAt":"2026-09-09T22:23:04.460Z","fetchedAt":"2026-11-03T10:23:51.609Z","normalizedAt":"2026-11-03T10:23:51.609Z"}]},"firstSeenAt":"2026-09-09T22:23:04.460Z","updatedAt":"2026-11-03T10:25:09.681Z"}
