Description from the maker (original English)
378k+ ERC-8004 agents and their security verifications. Two tools free, the rest USDC over x402.
These three are never merged into one score: opinions, measurements and popularity are different things.

Tool names and descriptions exactly as the server reported them on Nov 10, 2026. The maker wrote them, not us; we show them as plain text.
list_servicesFree. The catalogue: every tool on this server, what it returns, what it costs per call, and how to read the risk fields. Call this first — it is authoritative about pricing, needs no payment, key or wallet, and answers most questions about what this server can do without spendin
get_index_statsFree. How much of the ERC-8004 agent population this index covers: total agents synced from the on-chain Identity Registry, and how many carry verification results. Use it to judge whether the index is likely to know about the agent you care about before paying to look it up.
search_agentsSearch and filter scanned ERC-8004 agents by chain, risk score range, and verification status. Returns a paginated list with per-dimension scores (ETV, MCV, SCV, WAV, WV) and an overall risk score. Pass `wallet` or `id` to look up a single agent directly. IMPORTANT: read `risk_le
get_agentFetch the full detail record for a single agent by UUID, including verification state and metadata. Judge the agent by `risk_level`, not the raw overall_risk_score: 'not_verified' means nobody has paid to assess it yet and scores 100 by presumption, which is not a finding against
get_agent_activityFetch on-chain activity and liveness signals for one agent, including whether it is currently active and when it was last checked. Costs $0.002 USDC per call when paying with x402.
get_agent_reportFetch the full security assessment report for one agent: per-dimension findings, evidence and recommendations. Returns data only for agents owned by the caller — the wallet bound to your API key, or the wallet that paid via x402. Other agents return FORBIDDEN_NOT_OWNER. Use get_a

Security intelligence for ERC-8004 agents: search the on-chain agent index and read verification results.
Nothing to install. This is a remote MCP server — connect to the URL and the tools appear.
| Endpoint | https://erc8126scan.ai/api/mcp |
| Transport | streamable-http |
| Registry | uk.co.cybercentry/erc-8126-scan |
| Website | https://erc8126scan.ai |
Every agent minted in the ERC-8004 Identity Registry is indexed automatically — 378,000+ and counting. Each one carries verification results across five dimensions, produced by the Cybercentry verification services:
| Dimension | What it covers | |
|---|---|---|
| ETV | Token verification | The agent's token contract |
| SCV | Solidity code verification | The staking contract source |
| MCV | Media content verification | C2PA provenance of the agent's image |
| WAV | Web application verification | The agent's live site or dApp frontend |
| WV | Wallet verification | OFAC sanctions screening and funding-chain risk |
This server exposes that index. It does not run verifications — it serves results already computed and stored.
Remote servers are added as connectors, not through claude_desktop_config.json — that file is for local servers that run a command.
https://erc8126scan.ai/api/mcpAnything that speaks MCP over streamable HTTP can connect. Point it at:
https://erc8126scan.ai/api/mcp
Check your client's own documentation for where a remote MCP server URL goes — some use a settings pane, some a config file. If yours takes a config file, the field is the server URL rather than a command.
Six tools, all read-only. None of them mints, writes on-chain, or spends your credits.
Two are free — no payment, wallet or account:
| Tool | What it returns |
|---|---|
list_services | The catalogue: every tool, its price, and how to read the risk fields |
get_index_stats | How many agents are indexed, so you can judge coverage before paying |
The other four are paid:
| Tool | What it returns | Per call | Plan |
|---|---|---|---|
search_agents | Filter the index by chain, risk score range and verification status; paginated | $0.001 | Starter |
get_agent | Full detail for one agent by UUID | $0.001 | Starter |
get_agent_activity | On-chain activity and liveness for one agent | $0.002 | Starter |
get_agent_report | Full security assessment: per-dimension findings and evidence | $0.05 | Pro |
Call list_services first. It is free, and authoritative about current pricing.
get_agent_report returns data only for agents owned by the wallet bound to your API key. Other agents return FORBIDDEN_NOT_OWNER. Public scores for any agent are available through get_agent.
Tools you cannot reach on your plan are hidden from tools/list rather than listed and refused.
Judge an agent by `risk_level`, not `overall_risk_score`.
Scoring presumes risk: a check that applies to an agent but has not been verified counts as 100. So an agent nobody has paid to assess scores exactly the same as one assessed and found dangerous. Most of the index is the former.
risk_level separates them:
| Value | Meaning |
|---|---|
not_verified | Nobody has assessed this agent yet. Not a finding against it. |
not_assessed | No score recorded |
low / moderate / elevated / high | Verified, scoring in that band |
critical | Verified and genuinely high risk |
Treating a not_verified agent as dangerous is the most common way to misread this data.
Two free tools, then two ways to pay for the rest. tools/list is public, so an agent can see everything on offer and what it costs before deciding to pay for anything.
x402 — no account, no key. The client is quoted a price, pays in USDC, and retries. Pay on whichever chain you hold funds on:
Base eip155:8453 USDC
Solana mainnet USDC
| Tool | Per call |
|---|---|
list_services | free |
get_index_stats | free |
search_agents | $0.001 |
get_agent | $0.001 |
get_agent_activity | $0.002 |
get_agent_report | $0.05 |
An unpaid call returns a JSON-RPC error with code 402, carrying the payment requirements in error.data — the same shape as the Cybercentry verification server.
API key — for volume, or clients that do not speak x402 yet. Pass an erc8126_ key as a bearer token:
Authorization: Bearer erc8126_...
Keys come from erc8126scan.ai/my-api-keys. Calls draw on your plan's daily quota instead of being paid for individually, and tool availability and page sizes follow your tier. A key that is presented but invalid is rejected outright rather than quietly falling back to per-call billing.
Either way, get_agent_report is scoped to agents owned by the caller — the wallet bound to your key, or the wallet that paid.
