## Exfil surface

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

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

## Findings

No check matched anything in these tool definitions.


## Changes things (5)

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

### `check`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a URL (input.endpoint): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
PAID $0.25/call (x402, mcp-pricing-v1.1). Level-1 payment-flow conformance against a live x402 endpoint: quote (402 + parseable v2 PAYMENT-REQUIRED), requirements (accepts[] validity; payTo vs catalog/registration/expected_payto is a named finding), then a REAL probe purchase from our own wallet when an 'exact' entry on our rail advertises ≤ $0.05, and delivery-of-something. Above the cap or upto-only: depth 'quote_only' with the cap disclosed in gates. One signed payment_flow_conformance verdict out (verdict-v1.1.0).
```

### `diagnose`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a URL (input.endpoint): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
PAID $1.00/call (x402, mcp-pricing-v1.1). Seller-side funnel diagnosis for one x402 endpoint, as data: findability (catalog presence, listing age, description quality, capability-v1 category), conformance (check's real flow — quote, requirements, a REAL probe purchase when an 'exact' entry on our rail advertises ≤ $0.05, settle, deliver), category demand (verified earners, seller-deduped 30d revenue, median on-chain payment vs your price basis) and competition — then ONE primary blocker under a frozen disclosed precedence. One signed seller_diagnostic verdict out (verdict-v1.1.0).
```

### `discover`

- 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
FREE (rate-limited: 10/min burst, 120/hour per IP). Text of what you need in → sellers out with chain evidence (tier, verified revenue windows, real-buyer counts, on-chain-observed median price), the seller’s endpoint and payment details, their description and capability category (seller-asserted/auto-assigned claims, source-labeled), and their registered spec where one exists. Referral-only: you contract and pay the seller directly.
```

### `register`

- 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
Supply-side registration: $5 / 30 days (x402, mcp-pricing-v1.1) for actions start and renew; actions challenge_response, status and update_spec are free. You pay to be EXAMINED (EIP-191 ownership challenge + endpoint 402-conformance + registration-v1.0.0 schema validation) and can pay and fail — the fee buys the examination, never the outcome. Presence in discover is never gated by registration, and tier/rank/verdicts never move with it: registration adds claims-labeled data. SPEND-CAP WARNING: $5 = 5000000 micro-USDC is above the $1 default per-call cap many x402 clients ship — raise your client cap for start/renew or it will refuse to sign. Flow: start (submit spec, pay, receive a 72h challenge) → challenge_response (submit the payTo key’s EIP-191 signature; the audit runs) → registered while paid_through holds. renew re-audits and extends 30 days; renewal grace 7 days after paid_through — the mark itself drops at paid_through exactly.
```

### `verify`

- 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
PAID $0.10/call (x402, mcp-pricing-v1.1). Seller address or slug in → one signed seller_trust verdict out: the frozen score-v1.0.0 predicate re-evaluated at issuance, the chain evidence it rests on, exclusions applied, and full provenance — recomputable by anyone. Ed25519-signed over RFC 8785 canonical JSON.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `agenteconomy`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__agenteconomy__discover",
      "mcp__agenteconomy__verify",
      "mcp__agenteconomy__check",
      "mcp__agenteconomy__diagnose",
      "mcp__agenteconomy__register"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__agenteconomy__check`: outbound
- `mcp__agenteconomy__diagnose`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:25:23.968Z, unchanged since 2026-10-22T14:25:23.968Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |

| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `5` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 5 tools that change things (5 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.agenteconomy.cloud/mcp: tools/list returned 5 tools to an anonymous client, including discover (write), verify (write), check (write), diagnose (write), register (write)
