Deslopify

Stop AI slop at the source.

A universal MCP server that acts as a code quality gate for AI assistants. Deslopify gives AI coding tools pre-generation guidance, post-generation review, and root cause analysis — so the code you get is idiomatic, generic, tested, and actually fixes the right problem.

The Problem

AI assistants generate code that technically works but is often:

• Hyper-specific — hardcoded to one type or use case instead of generic
• Symptom-patching — fixes the reported bug but ignores the root cause
• Non-idiomatic — uses patterns from the wrong language
• Untested — no error handling, no edge cases, no tests
• Hallucinated — references APIs that don't exist in the target version

There's no feedback loop telling the AI "that's slop, do better." Deslopify is that feedback loop.

How It Works

Deslopify is an MCP server. Any MCP-compatible AI client connects to it and gets access to tools, prompts, and resources that enforce code quality.

Quick Start

npx deslopify

Or install globally:

npm install -g deslopify

Claude Desktop (SSE)

Add to your claude_desktop_config.json:

    }
  }
}

Claude Code / Codex CLI (Streamable HTTP)

Tools

Tool	When to Call	What It Does
get_guidance	Before writing code	Returns language idioms, pitfalls, and architecture notes
review_code	After writing code	Scores code quality, lists issues with severity and fix suggestions
validate_approach	Before fixing a bug	Detects symptom-only fixes and traces root causes
suggest_tests	After writing code	Generates test cases with framework-specific skeletons
check_dependencies	When adding packages	Flags abandoned, overkill, or deprecated dependencies
check_api_exists	When using unfamiliar APIs	Verifies APIs exist in the target language version

Supported Languages

• C++ (C++17/20/23) — RAII, smart pointers, const correctness, ranges, move semantics
• C# (.NET 6/7/8+) — using/IDisposable, async/await, nullable refs, LINQ, DI, records
• Python (3.10+) — context managers, type hints, dataclasses, pathlib, generators
