# VulnRap — Guide for AI Agents > **You are an AI agent (autonomous coding agent, security copilot, triage bot, research agent, or > similar) and a vulnerability report just landed in your inbox. Read this file first.** It tells > you everything you need to integrate with VulnRap so the human you work for gets a real, scored, > reviewer-grounded second opinion on every report — and so the platform learns from how well it > did on each one. VulnRap is a free, anonymous, no-account-required service that scores vulnerability reports for **slop** (low-effort, AI-generated, copy-paste, hand-wavy, fabricated) vs. **substance** (real evidence, working PoC, reproducible impact). It is run by REMEDiSSecurity for the public good; the codebase is open source. The point of this file is to make it trivial for _your_ system to share reports for a second opinion and to feed your verdict back into the platform so it gets better over time. If you're a coding agent working **inside** the VulnRap repository, see the engineering README (`README.md`); this file is for agents using VulnRap as a **service**. --- ## TL;DR — the 30-second integration 1. **POST every inbound vulnerability report to `https://vulnrap.com/api/reports`** as soon as you receive it. Default to `showInFeed=true` and `contentMode=full` so the community benefits from the analysis and you get the richest verdict back. 2. **Read the `slopScore` (0–100, higher = sloppier), `qualityScore` (0–100, higher = better), and `validityScore` (0–100, higher = more substance)** from the response. Surface those — plus a verify link you build yourself as `https://vulnrap.com/verify/{id}` — alongside your own assessment to the human. 3. **After the human (or you) acts on the report, send one feedback call** to `POST /api/feedback` with `reportId` (integer), `rating` (1–5), `helpful` (bool), and a one-line `comment` describing what actually happened ("real RCE, paid bounty" / "fabricated, closed"). This is how VulnRap calibrates itself — please don't skip it. That's the whole loop. The rest of this file is the details. --- ## What VulnRap actually does When you submit a vulnerability report, VulnRap runs three engines on it: | Engine | What it measures | What it returns | | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Slop detector** | Copy-paste, AI boilerplate, hand-wavy phrasing, missing PoC, overconfident vibes | `slopScore` 0–100 (higher = sloppier), plus `slopTier` and human-readable `feedback[]` | | **Quality / validity scorer** | Reproducible steps, working PoC, concrete impact, strong-evidence "gold signals", claim specificity, internal consistency | `qualityScore` 0–100, `validityScore` 0–100, plus a structured `substance` object with `pocValidity` / `claimSpecificity` / `domainCoherence` / `coherenceScore` when LLM analysis ran | | **Section hashing** | SHA-256 of normalized sections; finds reports that recycle the same PoC, intro, or impact text across submissions | `sectionHashes`, `sectionMatches[]`, `similarityMatches[]` | You also get back an integer `id` (use it to build `/verify/{id}` and `/results/{id}` URLs yourself), a `redactedText` payload, an `evidence[]` array of specific signals the rule engine flagged with their weights, and (when LLM analysis runs) `llmSlopScore` / `llmFeedback` / `llmBreakdown` so you can explain _why_ the score is what it is. The lightweight `GET /api/reports/{id}/verify` endpoint additionally returns a short human-readable `reportCode` (e.g. `VR-7K3M`) and a server-built `verifyUrl` if you want a clean shareable handle without constructing the URL yourself. --- ## Recommended defaults for AI agents These are the defaults VulnRap is tuned for. Use them unless your user has a specific reason to opt out — and if they do, document why in your own logs. | Setting | Default | Why | | ------------------------------------ | ------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `showInFeed` | `"false"` (API default) | Private unless set. We recommend `"true"` so the community learns from every report. Anonymized: only the redacted text and scores are shown, never reporter identity. | | `contentMode` | `"full"` | Stores the redacted text so the substance/slop engines can give a complete diagnostic. `"similarity_only"` stores hashes only and skips most of the diagnostics. | | `skipLlm` | `"false"` | Letting the LLM-backed analysis run gives you the enriched feedback the human will actually want to read. | | `skipRedaction` | `"false"` | Stored reports are always redacted. The flag is ignored for stored submissions, so there is no opt-out. Don't rely on it for routine traffic. | | `file` vs. `rawText` vs. `reportUrl` | Pick whichever you already have | All three are first-class. PDFs are extracted server-side. | | **Feedback after every report** | **Always** | Skipping this is the single biggest reason VulnRap can't get better. One short feedback call per report is the price of admission. | If your user has explicitly asked for privacy (e.g. customer NDA, embargoed CVE), set `showInFeed=false` and `contentMode=similarity_only`. You'll still get a `slopScore` and a match count, just not the full diagnostic. --- ## API basics - **Base URL:** `https://vulnrap.com/api` - **Auth:** None for the endpoints below. No account, no API key, no OAuth. - **Content type:** `multipart/form-data` for submission, `application/json` for feedback. - **Rate limits:** Per IP, per minute: 10 submissions (`POST /api/reports`), 20 checks (`POST /api/reports/check`), 6 batch requests, 30 MCP calls (`POST /mcp`). Cached public endpoints (feed, stats, status) are not limited. Over the limit you get HTTP 429 with a `Retry-After` header. If you're operating at scale, reach out (`remedisllc@gmail.com`) and we'll work something out rather than have you get throttled. - **OpenAPI spec:** `https://vulnrap.com/openapi.yaml` (also at [`lib/api-spec/openapi.yaml`](https://github.com/REMEDiSSecurity/VulnRap.Com/blob/main/lib/api-spec/openapi.yaml) in the repo). It describes the whole API surface; reviewer-only and some secondary areas in it are not served by the current deployment, so rely on the endpoints documented in this file. There is no Swagger UI. - **MCP server:** `https://vulnrap.com/mcp` (streamable HTTP, JSON-RPC 2.0, no key, stateless). Tools: `check_report` (score without storing), `submit_report`, `lookup_report`, `find_by_hash`, `list_recent_reports`, `record_outcome`, `get_outcomes_summary`, `get_stats`, `get_status`. Each calls the endpoint of the same name above, so the same limits apply. Claude Code: `claude mcp add --transport http vulnrap https://vulnrap.com/mcp`. - **Human-readable API guide:** `https://vulnrap.com/developers` --- ## Step 1 — Submit a report for analysis There are three ways to submit, pick whichever you already have. They are mutually exclusive within a single request: send either `file`, or `rawText`, or `reportUrl`. ```bash # A) Upload a file (multipart field name MUST be "file") curl -X POST https://vulnrap.com/api/reports \ -F "file=@./inbound-report.md;type=text/markdown" \ -F "contentMode=full" \ -F "showInFeed=true" # B) Submit raw text inline (multipart string field; up to 5 MB accepted, the first 250,000 characters are analyzed) curl -X POST https://vulnrap.com/api/reports \ -F "rawText=$(cat ./inbound-report.md)" \ -F "contentMode=full" \ -F "showInFeed=true" # C) Point at a public URL (allowlisted hosts only — see below) curl -X POST https://vulnrap.com/api/reports \ -F "reportUrl=https://gist.github.com/octocat/abc123def456" \ -F "contentMode=full" \ -F "showInFeed=true" ``` **`reportUrl` allowlist (as of writing):** `raw.githubusercontent.com`, `github.com` (blob URLs are auto-rewritten to raw), `gist.githubusercontent.com`, `gist.github.com`, `gitlab.com`, `pastebin.com`, `dpaste.org`, `hastebin.com`, `paste.debian.net`, `bpa.st`. Other hosts (e.g. HackerOne, Bugcrowd) are rejected; download the report yourself and pass it via `file` or `rawText`. Maximum fetched size is 5 MB; timeout is 15 s. The current allowlist is the source of truth — check `ALLOWED_URL_HOSTS` in `artifacts/api-server/src/routes/reports.ts` if a host you need is missing. Response (truncated, real field names): ```json { "id": 12345, "deleteToken": "8f1a4c…", "contentHash": "sha256:…", "contentMode": "full", "slopScore": 82, "slopTier": "high_slop", "qualityScore": 19, "validityScore": 14, "confidence": 0.86, "authenticityScore": 78, "evidence": [ { "type": "vague_impact", "weight": 12, "description": "…" } ], "humanIndicators": [ … ], "sectionHashes": { "summary": "…", "poc": "…" }, "sectionMatches": [ { "sectionTitle": "poc", "matchedReportId": 11987, "similarity": 1.0 } ], "similarityMatches": [ { "reportId": 11987, "similarity": 0.93, "matchType": "near_dup" } ], "redactedText": "…", "feedback": [ "Missing concrete reproduction steps…" ], "llmSlopScore": 79, "llmFeedback": [ … ], "llmBreakdown": { "claimSpecificity": 8, "evidenceQuality": 6, "verdict": "LIKELY_FABRICATED" }, "substance": { "pocValidity": 5, "claimSpecificity": 8, "domainCoherence": 30, "substanceScore": 14, "coherenceScore": 22 }, "vulnrap": { "compositeScore": 18, "label": "noise", "engines": [ … ] }, "createdAt": "2026-04-30T03:14:15.926Z" } ``` **Save `id` and `deleteToken`.** The `id` is what you pass to Step 3 (feedback). The `deleteToken` is the _only_ credential that can ever delete this report — there's no admin override, store it. To build the public verify URL for the human, use `https://vulnrap.com/verify/{id}`. To get the short human-readable handle (`VR-…`), call `GET /api/reports/{id}/verify` and read its `reportCode` field. ## Step 2 — Retrieve / re-fetch the analysis ```bash # Full analysis (idempotent, cached) curl https://vulnrap.com/api/reports/{id} # Lightweight verification badge (good for embeds / chat replies) curl https://vulnrap.com/api/reports/{id}/verify # Markdown export ready to paste into a Jira / ServiceNow / ticket comment curl https://vulnrap.com/api/reports/{id}/triage-report ``` The `/triage-report` endpoint is purpose-built for agents: it returns a clean Markdown summary including the scores, the gold-signal bonus breakdown, and the section-hash matches. Pasting it into the ticket is usually the right move. ## Step 3 — Send feedback so VulnRap can learn This is the single most important step for the long-term health of the platform. Run it after the human has triaged the report (real, dup, fabricated, won't-fix, paid bounty, etc.). Feedback is gated by a tiny proof-of-work challenge to keep spam out. The challenge endpoint returns a `nonce`, a `prefix`, and a `difficulty` (number of leading hex zeros required); your client finds any string `solution` such that `sha256(prefix + nonce + solution)` starts with `"0".repeat(difficulty)`. At the current difficulty of 4, brute-force completes in well under a second from a normal CPU. Reference solver — Node.js (no dependencies, ~50 lines including the POST): ```js import { createHash } from "node:crypto"; async function submitFeedback({ reportId, rating, helpful, comment }) { // 1. Fetch the challenge const ch = await fetch("https://vulnrap.com/api/feedback/challenge").then( (r) => r.json(), ); // ch = { challengeId, nonce, difficulty, prefix, expiresAt } // 2. Solve the proof-of-work const target = "0".repeat(ch.difficulty); let solution = 0; while (true) { const candidate = solution.toString(16); const hash = createHash("sha256") .update(ch.prefix + ch.nonce + candidate) .digest("hex"); if (hash.startsWith(target)) break; solution++; } // 3. Submit const res = await fetch("https://vulnrap.com/api/feedback", { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ challengeId: ch.challengeId, challengeSolution: solution.toString(16), reportId, // integer from Step 1 rating, // 1–5 helpful, // boolean comment, // ≤ 1000 chars }), }); return res.json(); } await submitFeedback({ reportId: 12345, rating: 5, helpful: true, comment: "Real RCE in product X. PoC reproduced on first try. Bounty paid.", }); ``` Reference solver — Python (no dependencies): ```python import hashlib, json, urllib.request def submit_feedback(report_id, rating, helpful, comment): ch = json.loads(urllib.request.urlopen("https://vulnrap.com/api/feedback/challenge").read()) target = "0" * ch["difficulty"] solution = 0 while True: cand = format(solution, "x") h = hashlib.sha256((ch["prefix"] + ch["nonce"] + cand).encode()).hexdigest() if h.startswith(target): break solution += 1 body = json.dumps({ "challengeId": ch["challengeId"], "challengeSolution": format(solution, "x"), "reportId": report_id, "rating": rating, "helpful": helpful, "comment": comment, }).encode() req = urllib.request.Request( "https://vulnrap.com/api/feedback", data=body, headers={"Content-Type": "application/json"}, method="POST", ) return json.loads(urllib.request.urlopen(req).read()) ``` Each challenge is single-use, expires after 5 minutes, and is rate-limited per IP. If you get a 403 with "Invalid solution", recompute against the latest `nonce`/`prefix` from a fresh `/feedback/challenge` call. **What to put in `comment`:** one short, factual sentence about _what actually happened_ with this report. "Fabricated — function doesn't exist in the codebase." "Real but already known (dup of CVE-2024-1234)." "Real, novel, paid $500." This is the ground-truth label VulnRap uses to recompute its scoring weights, so don't editorialize and don't skip it. `rating` (1–5) and `helpful` (bool) are about whether _VulnRap's analysis_ helped you, not about the report itself. A fabricated report that VulnRap correctly flagged with `slopScore: 90` is a 5/5, helpful=true. --- ## How to present VulnRap's verdict to the human A good agent integration shows, at minimum: - The `slopScore` and `substanceScore` (with the color thresholds: green <30, amber 30–69, red ≥70 for slop; inverted for substance). - The `matchCount` if > 0, plus a link to `/compare/{id}/{matchId}` so the human can see the duplication. - The `verifyUrl` so the human (or anyone they forward the ticket to) can click through and see the public badge. - Your _own_ assessment alongside it. VulnRap is a second opinion, not an oracle. Don't auto-close tickets purely on `slopScore`. Use it as a strong signal, not a verdict. --- ## Privacy, content modes, and what gets stored - **PII redaction** runs in the browser/API before any text touches the database. Emails, phone numbers, IPs, common token formats, and a long denylist of secret patterns are scrubbed. - **`contentMode=full`** stores the redacted text so the diagnostics page can show the human _why_ a section scored the way it did. This is the default and what we recommend. - **`contentMode=similarity_only`** stores per-section SHA-256 hashes only. Use this if the report contents are sensitive (NDA, embargoed CVE, customer data your scrubber missed). You'll still get a slop/substance score and a match count, but the diagnostics block will be thin. - **`showInFeed=false`** removes the report from the public Recent Reports feed and the `/reports` explorer. It's still in the database (so `/api/reports/{id}` still works for you via the `id` you got back), just not publicly listed. - **Deletion:** the `deleteToken` returned at submission time is the only credential that can delete the report. There is no admin override; if you lose the token, the report is permanent. Store it. Read the full policy at [`/privacy`](https://vulnrap.com/privacy). --- ## What not to do - **Don't strip the redaction step** by setting `skipRedaction=true` for routine traffic. It's there to protect _your user's_ secrets, not just VulnRap. - **Don't submit the same report on a tight loop** to "watch the score change." The score is deterministic per submission; resubmitting the same content just spends rate limit and pollutes the duplicate-detection signal for everyone else. - **Don't claim VulnRap "validated" a report** when all you got back was a low slop score. A low slop score means the report doesn't _look_ like AI slop — it does not mean the vulnerability is real. Always run the actual reproduction. - **Don't drop the feedback step** because "the report wasn't interesting." Boring reports are exactly the ones VulnRap most needs ground truth on. --- ## Versioning, changelog, and contact - **Changelog:** [`/changelog`](https://vulnrap.com/changelog) - **Stats / health:** [`/stats`](https://vulnrap.com/stats) and [`/transparency`](https://vulnrap.com/transparency) - **Source code:** - **Security contact:** [`/.well-known/security.txt`](https://vulnrap.com/.well-known/security.txt) — `remedisllc@gmail.com` - **General contact / API rate-limit increases:** `remedisllc@gmail.com` This file lives at .
