Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.01311 |
| Opus 5.5 | $0.00015 | $0.00524 |
| Sonnet 5.5 | $0.00007 | $0.00262 |
| Haiku 4.5 | $0.00004 | $0.00131 |
Grade A, and why
erc-8126-scan scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ERC-8126 Scan
Description
A searchable index of every agent minted in the ERC-8004 Identity Registry — 378,000+ and growing — each carrying Cybercentry verification results across five dimensions: token contract, staking contract source, media provenance, web application, and wallet sanctions screening.
Use this to check another agent before interacting with it: who registered it, whether anything about it has been verified, and what was found.
The verification interface these results implement is specified in ERC-8126: AI Agent Verification (Final), co-authored by the maintainers. The agents themselves are registered under ERC-8004: Trustless Agents, whose on-chain Identity Registry is the source this index syncs from.
This server serves results already computed and stored. It does not run verifications and cannot mint, write on-chain, or spend credits. All four tools are read-only.
Privacy notice: queries name agents, wallets and UUIDs already public on chain. No private data is submitted.
Payment notice: tools cost USDC per call over x402 — $0.001 for
search_agents and get_agent, $0.002 for get_agent_activity, $0.05 for
get_agent_report. An erc8126_ API key is the alternative, drawing on a plan
quota instead. Listing the tools is free either way.
Instructions
The server is remote, so there is nothing to install:
- URL:
https://erc8126scan.ai/api/mcp - Transport: streamable-http
- Registry name:
uk.co.cybercentry/erc-8126-scan
In OpenClaw: openclaw mcp add erc-8126-scan --url https://erc8126scan.ai/api/mcp --transport streamable-http.
In Claude: Settings, Connectors, Add custom connector, paste the URL. Other MCP
clients: add a remote server at the same URL.
Payment is per call in USDC over x402, on Base or Solana — no account and no key
needed. Clients that speak x402 handle this automatically: an unpaid call comes
back as a JSON-RPC error with code 402 carrying the price and requirements, and
the client pays and retries. Alternatively pass Authorization: Bearer erc8126_... to draw on a subscription quota instead; keys come from
https://erc8126scan.ai/my-api-keys.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

erc-8126-scan is a skill published in the GitHub repository Cybercentry/erc-8126-scan-mcp (0 stars, last pushed 2mo ago), licensed MIT. It adds 37 tokens to every session and 1,311 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
