An MCP server that reviews your code the way a kernel maintainer would: bluntly, technically, without diplomacy.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"code-review-agent-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# Code Review Agent MCP > AI code review agent that doesn't sugarcoat. If your code is bad, it tells you. Bluntly. [](https://pypi.org/project/code-review-agent-mcp/) [](https://www.python.org/downloads/) [](https://opensource.org/licenses/MIT) [](https://github.com/astral-sh/ruff) An AI-powered MCP (Model Context Protocol) server that reviews your code the way experienced maintainers review patches on serious projects: technically, directly, without diplomacy. ## What it does - **AI code review** — reviews code snippets, files, git diffs, and commits - Returns findings with severity labels: `CRITICAL`, `MAJOR`, `MINOR`, `NIT`, `CLEAN` - Cites specific line numbers for every finding - Explains why something is bad, then how to fix it - Ends with a clear verdict: "Ship it." or "Do not merge until..." - **No false praise. No hedging. No apologies. No filler.** ## Why? Most AI code reviewers are trained to be polite. They preface criticism with "great work but...", they hedge with "you might want to consider...", they soften findings with "this could potentially be an issue". That's not how serious code review works. On real projects (Linux kernel, PostgreSQL, Redis, SQLite), maintainers review patches directly. They find problems and call them out clearly. They don't exist to make the author feel good — they exist to make the code better. This MCP encodes that tradition. The personality IS the product. ## Anti-RLHF engineering LLMs are RLHF-trained to be polite. This AI agent fights that with three layers: 1. **System prompt** — 12 core principles (code-not-coder, verdict-first, severity labels, line citations, no false praise, no hedging, no apologies, no filler, second pers…
