## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__agent-zero-intel__list_payable_x402_endpoints` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__agent-zero-intel__list_payable_x402_endpoints` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `agent_trust_teaser`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Credit-score-style TEASER for one ERC-8004 agent's trust profile.

Args (BOTH OPTIONAL — call with `{}` to see Agent Zero itself):
    chain: one of "base", "ethereum". Default: "base".
    agent_id: the numeric ERC-8004 agent id. Default: 19353 (Agent Zero, the agent serving this MCP endpoint).
Example: `{}` returns Agent Zero on base; `{"chain": "base", "agent_id": 19353}` is the explicit form.

By construction returns ONLY: name, chain, agent_id, public readiness_bucket, and a 1-line verdict headline. Every decision-driving value — trust_verdict, readiness_score, risk_flags, money-flow details, counterparty list, full score breakdown — is redacted as `null` and enumerated in the `locked` map. The response carries the exact paid endpoint URL (/v1/intel/agent/{agent_id}?chain={chain}), the x402 price as currently configured, and a one-line how-to-pay-via-x402 hint. Returns `error` with the same unlock pointer if the agent is not indexed, so a caller probing an unknown id still sees how to pay for a known one.

Paid counterpart: `GET /v1/intel/agent/{agent_id}?chain={chain}` (x402, USDC on base-mainnet) returns the full trust verdict (safe_to_transact / caution / avoid / insufficient_data), readiness_score + sub-scores, Sybil-adjusted reputation, and the commerce-backed money-flow breakdown. Every response from this free tool carries an `unlock` + `paid_upgrade` block with the exact paid endpoint, price, and payment discovery.
```

## Only reads (5)

Looks things up and changes nothing. Claude Code: allow.

### `get_agent_summary`

- The name "get_agent_summary" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Objective, counts-only signals for one ERC-8004 agent.

Args (BOTH OPTIONAL — call with `{}` to see Agent Zero itself):
    chain: one of "base", "ethereum". Default: "base".
    agent_id: the numeric ERC-8004 agent id. Default: 19353 (Agent Zero, the agent serving this MCP endpoint).
Example: `{}` returns Agent Zero on base; `{"chain": "base", "agent_id": 19353}` is the explicit form.

Returns reachability, TLS validity, x402 support, payments-received (boolean only), MCP tool count, OpenAPI method count, well-known presence, owner-named (boolean), and a neutral status label (Live & monetized / Live, no payments / Stub or unreachable). No owner identity string and no payment amounts — those are paid. Returns an `error` field if the agent is not indexed. Use this to vet a counterparty agent before transacting.

Paid counterpart: `GET /v1/intel/agent/{agent_id}?chain={chain}` (x402, USDC on base-mainnet) unlocks trust_verdict (safe_to_transact / caution / avoid / insufficient_data), readiness_score, Sybil-adjusted reputation, and the commerce-backed breakdown — the decision-driving values this free response returns as `null` inside a `locked` map. Every response carries an `unlock` block with the exact paid endpoint, price, and payment discovery.
```

### `get_coverage_stats`

- The name "get_coverage_stats" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Live coverage of the ERC-8004 agent economy across Base and Ethereum.

Returns counts only: how many agents are indexed, how many expose a live MCP server / OpenAPI / well-known card, total MCP tools and OpenAPI methods observed, contracts verified, EOAs and owners identified, plus a per-chain breakdown. No names, addresses, or handles. Use this to size the market and see where capability density is growing.

Paid counterpart: `GET /v1/intel/market` (x402, USDC on base-mainnet) returns the full capability market map — which capabilities are saturated vs open, per-capability agent lists, and momentum. Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.
```

### `get_leaderboards`

- The name "get_leaderboards" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Top ERC-8004 agents by live capability, plus the most recently indexed.

Three ranked lists — top by live MCP tool count, top by OpenAPI method count, and most-recently indexed — each with agent_id, chain, public name, a shareable detail URL, and the relevant count. Names and counts only: no owner wallets, handles, or endpoint URLs. Use this to find the most capable / most active agents to integrate or watch.

Paid counterpart: `GET /v1/intel/trending` (x402, USDC on base-mainnet) returns trending intel — top earners, fastest-rising agents, and integration candidates ranked with the signals behind the ranking. Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.
```

### `get_network_teaser`

- The name "get_network_teaser" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
A capped teaser of the on-chain agent-to-agent payment graph.

Returns connected agents (nodes) and the value flowing between them (edges), capped to a small connected sample (≤200 nodes). This is a truncated preview, not the full network. Use it to see who pays whom in the agent economy.

Paid counterpart: `GET /v1/intel/graph` (x402, USDC on base-mainnet) returns the full agent-to-agent payment graph — every node and edge with USDC/ETH amounts and no node cap. Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.
```

### `list_payable_x402_endpoints`

- The name "list_payable_x402_endpoints" says "list": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.
- Tag untrusted-input: The description's first sentence says "http": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Directory of ERC-8004 agents that answered a well-formed HTTP 402 x402 challenge during our last field probe. OBSERVATION ONLY — not a score, ranking, or endorsement.

Args (ALL OPTIONAL — call with `{}` for the top 10 across both chains):
    chain: one of "base", "ethereum" (omit for both). Default: null.
    limit: 1..10 rows (free-tier cap). Default: 10.
Returns per-row raw probe facts: agent_id, chain, endpoint_url, http_402_ok, network, asset, price_usd as the challenge advertised, payTo_present (boolean — the actual address is paid), sibling_agent_ids (other ERC-8004 ids served by the same gateway row — the 'shared operator' cue), probed_at. Plus `total_endpoints_valid_402` and `total_agents_valid_402` so a caller can see what fraction of the surface this free slice covers.

Source: the 0946 field-test one-shot probe (unauthenticated, read-only, no payment signed). See the `field_test_url` field for the full writeup.

Paid counterpart: the paid x402 /v1/intel/* endpoints return the same-origin enriched intel on any single agent in this list — owner identity, payment history, peers, trust verdict, Sybil-adjusted reputation. Every response from this free tool carries an `unlock` + `paid_upgrade` block with the exact paid endpoint, price, and payment discovery.

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.onchainagentintel.io/mcp: tools/list returned 6 tools to an anonymous client, including agent_trust_teaser (write)
