Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name

- Playwright Chromium (installed via playwright install chromium)
- A Gemini API key (or OpenAI / Anthropic if you change providers)
pip install codereaper
playwright install chromium
codereaper
When you first run codereaper, it prompts for your Gemini API key and saves it in your global ~/.cursor/mcp.json so Cursor can invoke it later.
```bash
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).
get_patch_diff
Retrieve the combined diff for a patch.
apply_patch
Apply a patch to source files (stores snapshots for rollback).
verify_patch
Re-run the browser agent to check for regressions after patching.
rollback_patch
Restore original files from pre-patch snapshots.
list_scans
List recent scans.
get_scan_status
Get detailed status of a scan.
