Leetcode Helper — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Leetcode Helper (Agent Skill) and scored it 100/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

Every scanned point with the score it earned and what moved between them.
First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
An MCP server that gives structured, AI-powered DSA guidance inside Claude Desktop or Claude Code — approach analysis, hints, complexity breakdowns, and more, without spoiling the solution.
| Tool | Input | What it returns |
|---|---|---|
get_approach | problem | Pattern, steps, TC/SC |
get_hint | problem + where stuck | Nudge, no spoilers |
get_complexity | problem + code | TC/SC breakdown per block |
post_solution | problem + accepted code | Discussion post ready to copy |
similar_questions | problem | 3–5 problems for the same pattern |
upsolve | problem + working code | Optimization direction, not solution |
Prerequisites: Node.js 18+, an ANTHROPIC_API_KEY
git clone https://github.com/Navoren/leetcode-helper.git
cd leetcode-helper
npm install
npm run buildAdd to .claude/settings.json (project or global):
{
"mcpServers": {
"leetcode-helper": {
"command": "node",
"args": ["d:/leetcode-helper/dist/index.js"],
"env": {
"ANTHROPIC_API_KEY": "your-key-here"
}
}
}
}Add to claude_desktop_config.json:
{
"mcpServers": {
"leetcode-helper": {
"command": "node",
"args": ["/absolute/path/to/leetcode-helper/dist/index.js"],
"env": {
"ANTHROPIC_API_KEY": "your-key-here"
}
}
}
}Getting an approach:
"Use get_approach on: Given an array of integers, return indices of two numbers that add up to target."
Getting a hint when stuck:
"Use get_hint — problem: two sum, stuck on: my nested loop works but is too slow"
Generating a discussion post:
"Use post_solution with my accepted Python solution for two sum"
Upsolving:
"Use upsolve — here's my O(n²) solution, help me think toward better"
