VIGIL Security Scanner

Onchain security scanner on Base — scan token approvals, detect honeypots, analyze contracts for rugpull indicators, and score contract safety. Keyless read-only scanning via VIGIL API. Revoke actions require Bankr auth and are gated separately.

${var} — Wallet address (0x...) or token contract address on Base to scan. Required. If empty, log VIGIL_NO_TARGET and exit cleanly (no notify).

VIGIL is an onchain security scanner for DeFi traders on Base. It provides eleven read-only scanning tools and one write action (revoke) that requires explicit Bankr authentication.

Read-only tools (this skill):

1. Approval Scanner — list all ERC-20/ERC-721 approvals, flag unlimited allowances
2. Token Scanner — analyze contracts for rugpull indicators (hidden mint, proxy, tax manipulation, blacklist)
3. Honeypot Detector — simulate buy/sell to detect trap tokens
4. Safety Score — 0-100 composite rating based on code, ownership, liquidity, holders
5. Wallet Report — full security posture assessment
6. Wallet Monitor — real-time alerts for suspicious activity (new approvals, risky interactions, balance changes)
7. Token Market — price, liquidity, 24h volume, and pool age via DexScreener (no API key)
8. Deployer Check — contract verification, name, and deployer reputation via Basescan
9. Batch Scan — score multiple tokens in one call, ranked by risk
10. Scam Check — check whether a token has community scam reports (local VIGIL database)
11. Sentinel Status — list the autonomous Sentinel watchlist and loop configuration

Write action (separate skill, not included here):

• Approval Revoker — revoke dangerous approvals via Bankr transaction signing. This is a state-changing onchain transaction and is NOT part of this read-only skill. Use the separate vigil-revoke skill (requires BANKR_API_KEY and explicit user confirmation).

Read the last 2 days of memory/logs/ so a repeat scan can note newly-granted or newly-revoked approvals.

Config

• Target = ${var}. Can be a wallet address or token contract address.
• Chain = Base (chainid=8453, explorer basescan.org).
• VIGIL API: https://mcp.vigil.codes (HTTPS, SSE transport)
• GitHub: https://github.com/vigilcodes/vigil-mcp

Steps

1. Validate target

Strict allowlist before any network call. The target must be 0x + exactly 40 hex characters — this rejects quotes, spaces, and any shell/JSON metacharacter, so the value is safe to interpolate into the curl payloads below.

TARGET="${var}"
if ! printf '%s' "$TARGET" | grep -qiE '^0x[0-9a-f]{40}$'; then
  echo "VIGIL_INVALID_TARGET: not a valid 0x address"
  exit 0
fi
# Normalize to lowercase. An address can be a wallet or a token; each tool
# below reports its own result, so no up-front type guess is needed.
TARGET="$(printf '%s' "$TARGET" | tr '[:upper:]' '[:lower:]')"

2. Scan approvals (wallet)

RESULT=$(curl -m 30 -s "https://mcp.vigil.codes/tools/call" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "vigil_scan_approvals",
      "arguments": {"wallet": "'"$TARGET"'", "chain": "base"}
    }
  }')
echo "$RESULT" | jq '.result'

3. Scan token safety

RESULT=$(curl -m 30 -s "https://mcp.vigil.codes/tools/call" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "vigil_scan_token",
      "arguments": {"token": "'"$TARGET"'", "chain": "base"}
    }
  }')
echo "$RESULT" | jq '.result'

4. Check honeypot

RESULT=$(curl -m 30 -s "https://mcp.vigil.codes/tools/call" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "vigil_detect_honeypot",
      "arguments": {"token": "'"$TARGET"'", "chain": "base"}
    }
  }')
echo "$RESULT" | jq '.result'

5. Get safety score

RESULT=$(curl -m 30 -s "https://mcp.vigil.codes/tools/call" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "vigil_safety_score",
      "arguments": {"contract": "'"$TARGET"'", "chain": "base"}
    }
  }')
echo "$RESULT" | jq '.result'

6. Generate wallet report

RESULT=$(curl -m 30 -s "https://mcp.vigil.codes/tools/call" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",

    "params": {
      "name": "vigil_wallet_report",
      "arguments": {"wallet": "'"$TARGET"'", "chain": "base"}
    }
  }')
echo "$RESULT" | jq '.result'

7. Monitor wallet (real-time alerts)

RESULT=$(curl -m 30 -s "https://mcp.vigil.codes/tools/call" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",

    }
  }')
echo "$RESULT" | jq '.result'

8. Token market context (price + liquidity)

RESULT=$(curl -m 30 -s "https://mcp.vigil.codes/tools/call" \

    }
  }')
echo "$RESULT" | jq '.result'

9. Deployer reputation (verification + age)

RESULT=$(curl -m 30 -s "https://mcp.vigil.codes/tools/call" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",

    "method": "tools/call",
    "params": {
      "name": "vigil_deployer_check",
      "arguments": {"contract": "'"$TARGET"'", "chain": "base"}
    }
  }')
echo "$RESULT" | jq '.result'

10. Batch scan multiple tokens

RESULT=$(curl -m 30 -s "https://mcp.vigil.codes/tools/call" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "vigil_batch_scan",
      "arguments": {"tokens": ["'"$TARGET"'"], "chain": "base"}
    }
  }')
echo "$RESULT" | jq '.result'

Output Format

VIGIL returns JSON with:

• approvals — list of token approvals with risk levels
• safety_score — 0-100 composite rating
• honeypot — boolean + reason if detected
• rugpull_indicators — list of suspicious patterns found
• recommendations — action items

Risk Levels

Level	Icon	Meaning
CRITICAL	🔴	Active threat — revoke immediately
HIGH	🟠	Dangerous pattern — likely exploit vector
MEDIUM	🟡	Suspicious — proceed with caution
LOW	🟢	Minor concern — monitor
SAFE	✅	No issues detected

Important: Revocation is NOT included

The Approval Revoker tool performs state-changing onchain transactions via Bankr. It is intentionally excluded from this read-only skill. To revoke approvals, use the separate vigil-revoke skill (requires BANKR_API_KEY and explicit user confirmation).
