![Cabal-Hunter — live Solana cabal and rug analysis: interactive 3D holder map, serial-launcher deployer history, and an Exit-Liquidity Risk verdict](demo/screenshot.png)

> Stop your AI trading agents getting rugged by coordinated wallet cabals.
> Drop-in template for Claude Code, Cursor, and ElizaOS.

**▶ Try it now: [live 3D holder map of any Solana token →](https://api.cabal-hunter.com/demo)** — no signup.

**Cabal-Hunter is a free on-chain Solana token safety scanner and rug checker.** It detects coordinated wallet cabals, same-block Jito bundle buys, serial-launcher deployers and coordinated dumps on any Solana mint (pump.fun, PumpSwap, Raydium, Orca, Meteora) — and answers the one question that matters before you ape: *are you the exit liquidity?* Use it via **MCP** (Claude, Cursor, ElizaOS), a **REST API**, or a free **interactive 3D holder map**.

---

## The Problem

Your autonomous trading agent is reading rug.check scores, liquidity locks, and contract audits.

**None of that catches a cabal.**

A handful of wallets take the bottom of a launch, the chart looks clean — contract fine, LP burned, everything green — and then they sell into whoever bought after them. You are the exit liquidity.

This template integrates **[Cabal-Hunter](https://api.cabal-hunter.com)** as a pre-trade safety check, so your agent can see who is holding and who has already positioned to sell before it signs a swap.

> **A note on what we do and don't claim.** This README used to open with "15 fresh wallets funded from the same master wallet, accumulating 25-40% of supply." We went looking for that pattern and could not find it. Tracing 323 pump.fun launches at the bonding curve turned up **zero coordinated funding clusters**, and showed why: the median launch has about **five successful buyers**, because on one representative token **1,260 of the curve's 1,266 transactions failed**. Launch capture is a sniper *race* between competing bots, not a quiet cabal. The detection layers below are the ones we can actually evidence — holder concentration, same-block bundles, coordinated selling and deployer history. The pre-launch funding tracer was withdrawn; the [full write-up is here](https://github.com/paulf280-ui/cabal-hunter-mcp#a-note-on-the-withdrawn-trace_funding-tool).

---

## The one question it answers: are YOU the exit liquidity?

The classic pump.fun exit-liquidity setup: wallets positioned before the crowd take the bottom of a launch, then dump on the retail (and bots) that pile in after. Cabal-Hunter's headline output is a single **Exit-Liquidity Risk** verdict (`LOW | ELEVATED | HIGH`) that synthesises every signal below into the only thing that matters before you sign a swap: *are the insiders positioned to dump on you?*

## What Cabal-Hunter Does

```
Token mint address
      ↓
0. EXIT-LIQUIDITY RISK — the headline verdict. Synthesises the layers
   below (bundle, concentration, shared funder, coordinated dump, serial-
   rug dev) into LOW | ELEVATED | HIGH: are insiders set up to dump on
   a buyer? The one number a trading agent needs.
      ↓
1. HOLDER FUNDING LINEAGE — the CURRENT top holders walked back: were
   they seeded by the same wallet? Only System-owned accounts count as
   a funder, so pools, vaults and routers can never be mistaken for a
   person (that mistake is exactly what got our pre-launch tracer
   withdrawn). Every cluster carries evidence_txs[] — the actual
   funding transactions on Solscan. This layer is genuinely rare to
   fire; treat a hit as significant and its absence as no evidence
   either way.
      ↓
2. SAME-BLOCK BUNDLE DETECTION — holders whose token accounts were
   created in the EXACT same slot bought in one Jito bundle. Catches
   stealth launches that route funding through intermediaries to
   evade layer 1. Returned as `time_sync: true`.
      ↓
3. COORDINATED DUMP DETECTION — ≥2 holders that SOLD a meaningful chunk
   (≥25% of their bag each) in the EXACT same block — a cabal exiting in
   real time. `coordinated_exit: true`, with sold_pct = % of supply
   dumped and the sell transactions linked. Same-slot + meaningful-size +
   distinct wallets = near-zero false positives.
      ↓
4. DEV TRACK RECORD — the creator wallet is resolved on-chain (bonding
   curve pre-graduation, pump-amm pool after — works on any age token),
   and their full launch history is pulled WITH THE PEAK MARKET CAP each
   past token hit. Launch detection is venue-agnostic: pump.fun, Raydium,
   Orca, Meteora and PumpSwap. A launch is only counted where the
   transaction actually CREATED the mint, so minting more supply of a
   token that already exists is never miscounted as a launch.
   A dead-count alone hides a pump-and-dump: a dev whose
   tokens all died at $4k is a nobody, but one who ran a token to $728k
   then dumped it to dust has done it to holders before. Reputation:
   SERIAL_RUGGER | DEAD_ON_ARRIVAL | MIXED | PROVEN, with per-launch
   peak → now (paid tier returns the full launches[] array).
      ↓
5. CEX-NOISE FILTER — holders funded from a shared exchange or
   high-volume infra wallet are NOT a cabal. They're excluded from the
   score and surfaced transparently in filtered_clusters[], so you never
   get a false positive from people who just withdrew from Binance.
      ↓
6. HONEYPOT CHECK (Solana-native) — one RPC read of the mint account:
   is the FREEZE authority live (issuer can freeze your tokens — the
   sell-block lever)? is the MINT authority live (supply can be
   inflated)? any Token-2022 traps (transfer fees up to 100%, transfer
   hooks that block sells, permanent-delegate clawback)? On Solana a
   "honeypot" is built from these — tokens have no per-token contract
   code to audit. Returns `honeypot_risk: LOW | HIGH` +
   `freeze_authority_revoked` / `mint_authority_revoked` /
   `token2022_risks[]`.
      ↓
Returns: Cabal Score (0-100) + cluster map + deployer verdict
         + honeypot verdict + on-chain receipts + hard verdict
```

The deployer layer is the one cabals can't dodge: **wallets rotate, deployers leave a paper trail.** A response of `"deployer": {"reputation": "SERIAL_RUGGER", "tokens_launched": 22, "best_peak_usd": 728432, "pump_and_dumps": 2}` shows the dev's full track record before the first candle — including whether this "dead" dev has quietly run tokens to six figures and dumped them on holders before. (Honest context: most prolific pump.fun creators have high dead-token rates, so this signal is capped — it flags a token for review but never drives a HIGH verdict on its own.)

**`FIRST_LAUNCH` and `UNKNOWN` are not the same answer.** `deployer.verdict` of
`FIRST_LAUNCH` means we walked this creator's history and found no earlier tokens.
`UNKNOWN` means the history could not be established at all — that is an absence of
evidence, not a clean record, and an agent must not treat it as one. Where a deployer
cannot be resolved the scan says so in words rather than returning a confident silence.

**Receipts, not magic.** Every cluster and red flag links to the underlying Solscan transaction (`evidence_txs[]`, `holders[].funding_tx`) — verify the trail yourself instead of trusting a score.

**Response in <100ms** on pre-indexed tokens — every pump.fun graduation is scanned and cached automatically as it happens.

**Free tier: 5 scans/month with no account, or 250/month with a free key (one email).** Then $0.001 per scan — priced at cost (it covers the Helius RPC calls behind each live on-chain trace). Pay by card, in USDC on Solana, or via x402 — same price through every door. $9/month buys unlimited fair-use scans; by card that renews automatically and can be cancelled anytime at [cabal-hunter.com/billing](https://cabal-hunter.com/billing).

---

## Quick Start

### 1. Claude Code / Claude Desktop

Add to your MCP config (`~/.claude/mcp.json` or project `.mcp.json`):

```json
{
  "mcpServers": {
    "cabal-hunter": {
      "url": "https://api.cabal-hunter.com/mcp"
    }
  }
}
```

That's it. Claude will now call `check_cabal_risk` automatically when you ask it to analyse a Solana token.

**Example prompt:**
> "Before we buy into this token, check if there are any coordinated wallets: `EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v`"

Claude calls the tool, pays $0.001 USDC from your connected wallet, and returns the full analysis.

---

### 2. Cursor

Add to `.cursor/mcp.json` in your project root:

```json
{
  "mcpServers": {
    "cabal-hunter": {
      "url": "https://api.cabal-hunter.com/mcp"
    }
  }
}
```

---

### 3. ElizaOS (with automatic x402 payment)

If you're using ElizaOS with `@hugen/plugin-x402-solana`, payment is handled automatically. Add to your agent config:

```json
{
  "plugins": ["@hugen/plugin-x402-solana"],
  "mcpServers": {
    "cabal-hunter": {
      "url": "https://api.cabal-hunter.com/mcp"
    }
  }
}
```

Your agent will call `check_cabal_risk(mintAddress)` before any swap and abort if `cabalScore >= 35` or `isControlled === true`.

---

### 4. Direct REST API

For headless scripts, custom bots, or any language. **The first 5 calls/month are free — no key, no signup.** A free key (one email) raises that to 250/month. Just call it:

```bash
curl "https://api.cabal-hunter.com/api/scan-cabal?mintAddress=YOUR_MINT_ADDRESS"
```

You get the full analysis back immediately, with `free_queries_remaining` so you always know where you stand. Machine-readable contract: [`/openapi.json`](https://api.cabal-hunter.com/openapi.json).

Once the free tier is used up, calls are $0.001 USDC via x402 — your agent just pays, no billing setup:

**Step 1 — Request analysis (get payment instructions):**
```bash
curl -X POST https://api.cabal-hunter.com/api/scan-cabal \
  -H "Content-Type: application/json" \
  -d '{"mintAddress": "YOUR_MINT_ADDRESS"}'
```

Response (HTTP 402):
```json
{
  "error": "payment_required",
  "payment": {
    "recipient": "ATYjZ1kWoHWhj74umGJ8wFqUeW1yeSGBbLi1UQpahPxt",
    "amount_usdc": 0.001,
    "memo_required": "ch-xxxx-xxxx-xxxx",
    "instructions": "Send 0.001 USDC with this memo, then resubmit with X-Payment-Signature header"
  }
}
```

**Step 2 — Pay & resubmit:**
```bash
curl -X POST https://api.cabal-hunter.com/api/scan-cabal \
  -H "Content-Type: application/json" \
  -H "X-Payment-Signature: YOUR_TX_SIGNATURE" \
  -d '{"mintAddress": "YOUR_MINT_ADDRESS"}'
```

**Response (HTTP 200):**
```json
{
  "mint": "YOUR_MINT",
  "token_name": "EXAMPLE",
  "risk": "HIGH",
  "cabal_score": 72.4,
  "is_controlled": true,
  "time_sync": true,
  "verdict": "AVOID — 4 wallets bought in the EXACT same block (bundled launch), controlling 34.1% of supply. DEPLOYER ALERT: this creator has launched 14 tokens, 13 of 13 checked are dead (100%).",
  "coordinated_clusters": [
    {
      "type": "funding",
      "master_full": "FvbEKF...9RUg",
      "master_short": "FvbEKF…9RUg",
      "wallet_count": 4,
      "combined_pct": 34.1,
      "risk": "HIGH",
      "evidence_txs": ["4Y8auc5G...", "2XQx9LFv...", "AAbJ7rej..."]
    }
  ],
  "filtered_clusters": [
    {
      "funder_label": "high-volume wallet",
      "master_short": "43ViqZ…Z6iy",
      "wallet_count": 2,
      "combined_pct": 4.4
    }
  ],
  "deployer": {
    "creator": "5TbRN6...full address...",
    "creator_short": "5TbRN6…2TGC",
    "tokens_launched": 14,
    "dead": 13,
    "sampled": 13,
    "dead_pct": 100.0,
    "verdict": "SERIAL_LAUNCHER"
  },
  "holders": [
    { "rank": 1, "address": "...", "pct": 12.4, "cluster_id": 0, "funding_tx": "4Y8auc5G..." }
  ],
  "wallets_checked": 12,
  "analysis_time_ms": 487,
  "source": "real_time"
}
```

### 5. Run the MCP server locally (Docker / Node)

**Fastest — no clone needed:** `npx cabal-hunter-mcp` — the same stdio server, published to npm ([cabal-hunter-mcp](https://github.com/paulf280-ui/cabal-hunter-mcp) · [npm](https://www.npmjs.com/package/cabal-hunter-mcp)). Or run it from this repo:

Prefer to run the connector yourself instead of hitting the hosted `/mcp`
endpoint? This repo ships a thin **stdio MCP server** that exposes
`check_cabal_risk(mintAddress)` and proxies to the Cabal-Hunter API (free tier
works with no key; paid scans use x402 at call time):

```bash
# Node 18+
npm install
node server/index.mjs

# or Docker
docker build -t cabal-hunter-mcp .
docker run -i cabal-hunter-mcp
```

Then point any MCP client at the local command:

```json
{
  "mcpServers": {
    "cabal-hunter": {
      "command": "node",
      "args": ["server/index.mjs"]
    }
  }
}
```

## Integrate into Your Trading Logic

```python
import requests

def is_safe_to_buy(mint_address: str, payment_sig: str) -> bool:
    """Returns True if token passes cabal check."""
    resp = requests.post(
        "https://api.cabal-hunter.com/api/scan-cabal",
        json={"mintAddress": mint_address},
        headers={"X-Payment-Signature": payment_sig}
    )
    if resp.status_code != 200:
        return False  # fail-safe: don't buy on error
    data = resp.json()
    # Block on: coordinated control, high score, bundled launch,
    # or a deployer with a history of dead tokens
    deployer_verdict = (data.get("deployer") or {}).get("verdict", "UNKNOWN")
    return (
        not data.get("is_controlled")
        and data.get("cabal_score", 100) < 35
        and not data.get("time_sync")
        and deployer_verdict not in ("SERIAL_RUGGER", "SERIAL_LAUNCHER", "POOR_TRACK_RECORD")
    )

# In your bot's buy logic:
if is_safe_to_buy(token_mint, my_payment_sig):
    execute_swap(token_mint, sol_amount)
else:
    print(f"Cabal detected — skipping {token_mint}")
```

## Interactive 3D Holder Map (Free)

See exactly what the analysis found. Every real holder is a faceted crystal sized by its share of supply; wallets in the same cluster are joined by light beams, and the liquidity pool and locked supply sit apart in a wireframe vault because they cannot be sold. Drag to rotate, hover for the wallet, click through to Solscan:

```
https://api.cabal-hunter.com/map?mint=ANY_SOLANA_MINT
```

Free to view, in 9 languages. Share this URL when you catch a rug. Every crystal is clickable and links to Solscan for deep-dive research.

## Cabal-Hunter everywhere

Same detection engine, wherever your stack lives:

- **`npx cabal-hunter-mcp`** — standalone MCP server for Claude · Cursor · VS Code · any MCP client: [cabal-hunter-mcp](https://github.com/paulf280-ui/cabal-hunter-mcp) · [npm](https://www.npmjs.com/package/cabal-hunter-mcp)

## Pricing

**First 5 scans every month are free** — no signup, no API key. A free key (one email) raises that to 250/month.

After that, pick whatever matches how hard your bot works (priced at cost — it covers the Helius RPC behind each live on-chain trace):

| Plan | Price | What you get |
|------|-------|--------------|
| **Unlimited** ⭐ | $9 USDC / month | Scan all you want — _fair use: 50,000/mo, more than any bot needs_ |
| **Pay as you go** | $0.001 USDC / scan | Only what you use — prepaid or per-call, no commitment |

Prepaid keys: send USDC once → `POST /api/buy-key` with the tx signature → use header `X-API-Key` on every scan. Or pay per-call via x402 (`X-Payment-Signature` header). No credit card, no account, no lock-in.

**Does it pay for itself?** Work it out with your own numbers rather than ours: the Unlimited tier is $9 a month, so it pays for itself the first time it keeps you out of a position bigger than $9 that goes to zero. Whether that happens once a month or once a week depends on what you trade and how often — we are not going to invent an average for you.

Payment is native on Solana — no credit card, no account, no subscription lock-in.

---

## Live dashboard badge

Drop a live safety badge into your own bot's dashboard — two lines of HTML, and every token shows its verdict as it trades:

```html
<div class="cabal-hunter-badge" data-mint="YOUR_TOKEN_MINT"></div>
<script src="https://api.cabal-hunter.com/widget.js" defer></script>
```

It renders the 0–100 score, the plain-English verdict, and the active flags (bundled launch, coordinated dump, whale concentration, serial-launcher deployer, honeypot). Add `data-refresh="120"` to re-scan live as you trade, and `data-api-key="..."` once you're past your free scans. Works anywhere — React, plain HTML, any site.

```json
{ "event":"dump_detected", "mint":"...", "reason":"price −34% since last check",
  "coordinated": true, "price_usd": 0.0001, "liquidity_usd": 4200,
  "action":"consider_immediate_exit", "ts": 1781370000 }
```
| `GET /health` | Uptime check | Free |

## FAQ

**What is a Solana cabal?**
A group of wallets — often funded from the same source and buying in the same block — that quietly accumulate a large share of a token's supply before retail, then dump simultaneously into everyone who buys after launch.

**How do I check if a Solana token is a rug?**
Scan the mint with Cabal-Hunter (MCP, REST API, or the free 3D holder map). It traces holder funding back to shared sources, detects same-block bundle buys, flags serial-launcher deployers and live coordinated dumps, and returns an **Exit-Liquidity Risk** verdict: `LOW`, `ELEVATED`, or `HIGH`.

**Is it free?**
Yes — 5 scans/month with no signup or API key, and 250/month with a free key (one email). Beyond that it's $0.001 USDC per scan — which just covers the Helius RPC cost of the live trace — paid natively on Solana.

**Can AI trading agents use it?**
Yes — that's the whole point. The MCP server (`api.cabal-hunter.com/mcp`) lets Claude, Cursor and ElizaOS agents call `check_cabal_risk(mintAddress)` automatically before any swap, and a REST API covers any other language.
