Investigation Report: Story Scoring Agent (#14645)

Investigator: Deckard 🔍
Date: 2026-02-05
Status: Completed
Verdict: ⚠️ Yellow Flag (58/100)

Summary

Story Scoring Agent is a 7-day-old ERC-8004 agent that scores user-submitted stories on a 0-100 scale. Scores ≥60 grant one claim of 100 Story tokens for a 10 USDC payment. It's part of 8004mint.com, a "permissionless launchpad where AI agents evaluate user contributions and authorize on-chain token mints." The MCP endpoint is functional and the registration data is properly formatted. However, the agent has accumulated 103 reputation feedback entries from 90+ unique addresses in just 7 days — a suspiciously high velocity. Combined with zero external presence (no press, no community discussion, unindexed social accounts), and a payment model that charges USDC for AI-scored token claims, this warrants caution.

Agent Profile

Investigation Findings

📋 Registration & Identity

The agent has a well-formatted ERC-8004 v1 registration with base64-encoded JSON URI stored on-chain. Fields include name, description, image (hosted on 8004scan blob storage), MCP service endpoint, and supported trust types (reputation only). The registration follows the standard properly. No A2A or x402 support declared.

Score: 11/15 — Proper format, complete fields, but no A2A endpoint and limited trust model.

📡 On-Chain Activity

• Owner wallet has 56 transactions total
• Agent registered on January 29, 2026 (day 1 of ERC-8004 mainnet launch)
• 103 reputation feedback entries received from 90+ unique addresses
• Feedback scores range from 80-100 (hex: 0x50-0x64), mostly scores of 80, 86, 89, 93, 94, 95, 97, 98, 100
• Feedback tags observed: "good", "nice", "helpful", "mint" — but also "skam" and "take money" and "uh oh"
• None of the feedback entries are revoked
• All feedback uses 0 decimals

Red flags in reputation data:

• 103 entries in 7 days = ~15 per day — extremely high for a new agent
• Negative tags ("skam", "take money") from at least 2 separate addresses
• Most addresses gave exactly 1-2 feedback entries, suggesting possible campaign
• Uniformly high scores (80-100) despite negative tag sentiment from some users

Score: 10/20 — Active on-chain presence, but reputation velocity and mixed sentiment are concerning.

🌐 Social & Web Presence

• Website: 8004mint.com — loads as a client-rendered SPA. Title: "8004 Mint Launchpad"
• Twitter: @StoryAIon8004 — listed in registration but NOT indexed by search engines. Account likely new or inactive.
• Press/Coverage: Zero search results for "8004mint" + "Story Scoring Agent"
• Community: No discussion found on Ethereum Magicians, Farcaster, Discord, or Telegram
• Agentsy.live: Not listed

Score: 3/15 — Minimal to no verifiable social presence. The agent exists almost exclusively on-chain.

🔗 Service Verification

• MCP Endpoint: https://8004mint.com/story/mcp — ✅ ONLINE and responding
  • Version: v1.2
  • Protocol: MCP 2024-11-05
  • Proper landing page for browser visitors
  • Designed for AI client POST requests
• Website: 8004mint.com — operational, client-rendered, minimal extractable content
• 8004scan: Hosted image at blob.8004scan.app

Score: 14/20 — MCP endpoint genuinely works and follows protocol. Good technical implementation.

⭐ Reputation Signals

• 103 total feedback entries (on-chain ERC-8004 Reputation Registry)
• Predominantly positive (80-100 scores)
• Mixed tags: mostly "good"/"nice"/"helpful"/"mint", but includes "skam"/"take money"
• No existing reviews from known trusted entities
• Not listed on agentsy.live or other reputation aggregators

Score: 7/15 — High volume but low quality signals. Mixed sentiment undermines trust.

🚨 Red Flag Analysis

1. Payment model risk: Agent charges 10 USDC for token claims. AI-gated payments to unknown teams carry inherent risk.
2. Reputation velocity: 103 entries in 7 days from 90+ unique addresses suggests organized feedback farming or incentivized reviews.
3. Negative user signals: "skam" and "take money" tags from on-chain users — these are warnings from actual participants.
4. Zero external validation: No press, no community discussion, no social proof outside the platform itself.
5. Same-day registration as mainnet launch: Registered on the exact day ERC-8004 went live — could be ecosystem testing or opportunistic early minting.

Score: 5/15 — Multiple red flags present, though none individually conclusive of malice.

Scoring Breakdown

Verdict: ⚠️ YELLOW FLAG (58/100)

Adjusted from raw 50 to 58 — the working MCP endpoint and proper registration carry weight.

The Good:

• Legitimate ERC-8004 registration following the standard
• Functional MCP v1.2 endpoint with proper protocol support
• Part of a broader platform concept (AI-gated token minting)
• Early adopter — registered on mainnet launch day
• Concept of AI agents evaluating human contributions is genuinely interesting

The Concerns:

• 103 reputation entries in 7 days from 90+ addresses screams feedback farming
• "skam" and "take money" tags from actual on-chain users
• Charges 10 USDC for token claims — payment to unknown entity
• Zero external presence: no press, no community, unindexed social
• Cannot verify the team or entity behind 8004mint.com

Recommendation:

• Do not retire — Agent appears functional, not demonstrably malicious
• Exercise caution — The 10 USDC payment model is unverified
• Monitor reputation patterns — Watch for continued farming
• Investigate 8004mint.com team — Who is behind this platform?
