# ERC-8126 Scan

> 378k+ ERC-8004 agents and their security verifications. Two tools free, the rest USDC over x402.

- version: 1.0.1
- connection class: R1 (autonomous)
- trust: 97/100
- quality: 86/100 (good)

**An agent can connect on its own if it already holds `ERC_8126_SCAN_TOKEN`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "erc-8126-scan": {
      "type": "http",
      "url": "https://erc8126scan.ai/api/mcp",
      "headers": {
        "Authorization": "Bearer ${ERC_8126_SCAN_TOKEN}"
      }
    }
  }
}
```

Placeholders to fill: `${ERC_8126_SCAN_TOKEN}`.

## Quality 86/100 (good)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: search_agents (destructiveHint, idempotentHint); get_agent (destructiveHint, idempotentHint); get_agent_activity (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 992 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 992 tokens to load them all

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `get_agent`: Fetch 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 the agent. Costs $0.001 USDC per call when paying with x402.
- `get_agent_activity`: Fetch 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_report`: Fetch 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_agent for public scores on any agent. Costs $0.05 USDC per call when paying with x402.
- `get_index_stats`: Free. 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.
- `list_services`: Free. 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 spending anything.
- `search_agents`: Search 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_level`, not `overall_risk_score`, to judge an agent. Scoring presumes risk, so an agent nobody has paid to verify scores 100 exactly like one assessed as dangerous. risk_level separates them: 'not_verified' means unassessed and is NOT a finding against the agent, while 'critical' means verified and genuinely high risk. Most indexed agents are 'not_verified'. Costs $0.001 USDC per call when paying with x402.
