How do I install the codereaper mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `GEMINI_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Codereaper MCP Server?

AI-driven JavaScript dead code elimination for Cursor (MCP server)

What the server does

CodeReaper is an AI-driven MCP tool for Cursor that finds and removes dead JavaScript by exploring real UIs and capturing V8 coverage.

Autonomous UI exploration via the Index browser agent
V8 precise coverage to identify zero-execution functions
Risk scoring and removal recommendations
Patch generation and optional verification replay
MCP integration for Cursor workflows

Credentials and setup notes

Python 3.11+ - Playwright Chromium (installed via playwright install chromium) - A Gemini API key (or OpenAI / Anthropic if you change providers)

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
find_dead_code	Full pipeline: scan + analyze. Returns dead-code report with file paths, line numbers, risk scores, and removal recommendations.
scan_website	Scan only (no analysis). Returns scan_id for later use.
analyze_dead_code	Analyze a completed scan. Takes scan_id.
generate_patches	Generate unified diffs to remove dead code (conservative / balanced / aggressive).
