## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 66/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 76/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 819 tokens (~136/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 97/100
  - Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (6)

### `list_services` (~69 tokens)

List services and prices

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.

### `get_index_stats` (~66 tokens)

Index coverage

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.

### `search_agents` (~324 tokens)

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.

Input parameters:

- `chain` (string): Filter by chain, e.g. 'base', 'ethereum'.
- `id` (string): Look up one agent by its UUID.
- `limit` (integer): Page size. Capped by your plan tier.
- `max_score` (integer): Maximum overall risk score (0-100).
- `min_score` (integer): Minimum overall risk score (0-100).
- `order` (string): Sort direction. Defaults to desc.
- `page` (integer): Page number, 1-indexed.
- `sort` (string): Sort field. Defaults to created_at.
- `verified` (string): Filter by verification status.
- `wallet` (string): Look up one agent by registrant or agent wallet address.

### `get_agent` (~95 tokens)

Get agent detail

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.

Input parameters:

- `id` (string, required): Agent UUID.

### `get_agent_activity` (~58 tokens)

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.

Input parameters:

- `id` (string, required): Agent UUID.

### `get_agent_report` (~98 tokens)

Get agent security 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.

Input parameters:

- `id` (string, required): Agent UUID.

## Common questions

### What is the ERC-8126 Scan MCP server?

ERC-8126 Scan is an MCP server listed in the public MCP registry as uk.co.cybercentry/erc-8126-scan. 378k+ ERC-8004 agents and their security verifications. Two tools free, the rest USDC over x402. This page covers its hosted endpoint (https://erc8126scan.ai/api/mcp).

### Is the ERC-8126 Scan MCP server safe to use?

ERC-8126 Scan scores 80 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the ERC-8126 Scan MCP server expose?

ERC-8126 Scan exposes 6 tools: list_services, get_index_stats, search_agents, get_agent, get_agent_activity, get_agent_report. Their descriptions and schemas cost roughly 710 tokens of context every time the server is loaded.

### Does the ERC-8126 Scan MCP server require authentication?

No. We connected to ERC-8126 Scan without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the ERC-8126 Scan MCP server still maintained?

ERC-8126 Scan is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
