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 | $0.00033 | $0.01283 |
| Opus 5 | $0.00016 | $0.00642 |
| Sonnet 5 | $0.00007 | $0.00257 |
| Haiku 4.5 | $0.00003 | $0.00128 |
Grade A, and why
cybercentry-verification 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 9d 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.

Cybercentry Verification
Description
Security verification for wallets, tokens, smart contracts, AI agents and web applications, paid per call in USDC over x402 on Base or Solana. No account, no API key, no subscription. Two tools are free and need no wallet at all.
Use this before trusting something: a wallet you are about to transact with, a token you are about to buy, Solidity you are about to call, a dApp frontend you are about to connect to, or another agent's configuration.
Wallet verification covers 31 EVM chains and screens against the OFAC SDN list. The maintainers co-authored ERC-8126 and ERC-8196, both Final, on AI agent verification and agent-authenticated wallets, and ERC-8376, a Draft standard on token launch abuse detection whose detection contracts are live on Base.
Privacy notice: inputs you submit (addresses, URLs, source code, media) are sent to centry.cybercentry.co.uk for analysis. Only submit content the user is comfortable sharing.
Payment notice: the paid tools cost $1.00 per call in USDC. Free tools cost nothing and require no wallet.
Instructions
Prefer the MCP server. It is remote, so there is nothing to install:
- URL:
https://centry.cybercentry.co.uk/api/mcp - Transport: streamable-http
- Registry name:
uk.co.cybercentry/verification
In OpenClaw: openclaw mcp add cybercentry --url https://centry.cybercentry.co.uk/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.
Everything below is also reachable over plain HTTP if MCP is unavailable:
POST https://centry.cybercentry.co.uk/api/services/<service> with a JSON body.
The machine-readable contract is at
https://centry.cybercentry.co.uk/openapi.json.
Always try the free tools first
Neither takes payment and neither needs a wallet.
list_services: the live catalogue with current prices. This is the authoritative list; the tools below are a snapshot of it.recent_exploits: recent real-world exploits with losses, attack vectors and the service that addresses each. Takes an optionallimit(default 10).
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.

cybercentry-verification is a skill published in the GitHub repository Cybercentry/verification-mcp (2 stars, last pushed 18d ago), licensed MIT. It adds 33 tokens to every session and 1,283 once invoked, about $0.0002 per session on Opus 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.
