## Exfil surface

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

| 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. | `mcp__paddock__verify_before_pay` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__paddock__check_payee` |

## Findings

- **info** Long descriptions in `verify_before_pay` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,127 characters long, over the 2,000 this check looks for.

description ends: "...and a URL a third party can verify independently against Paddock's published key."
```

- **warn** Annotations that disagree with the tool in `verify_before_pay` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "verify_before_pay" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The name "verify_before_pay" says "pay": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `verify_before_pay`

- The name "verify_before_pay" says "pay": a word that usually means money moves, which cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info long-description, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Should my agent pay this endpoint right now? Free key - a free pk_free_ key covers it against a shared 10 calls/day; $0.25 per call via x402 beyond it. Over MCP only, 1 free trial call/day is available without a key. CALL THIS BEFORE YOUR AGENT AUTHORIZES ANY x402 PAYMENT. An unpaid GET and POST at query time decode the 402 from the body AND the payment-required header; HTTP 200 is never treated as live. A contract mismatch is route:false and names the field (network, asset, seller, price). Includes independent paid-fulfillment results where available — whether a third party has actually paid this endpoint and got a valid response back, with the settlement hash. Test the result with route === true: the string "inconclusive" is truthy, and it is the one case where you must not pay on our say-so. The bias is deliberate: where evidence is incomplete, verify_before_pay favors inconclusive over a false pass — it will more often decline to clear a good endpoint than clear a bad one. route: true means the live contract matched your expectations — it is not an all-clear on every signal: stale settlement, a circular flag, a payTo divergence, and a failed request pre-flight can each coexist with it, so read the checks block rather than route alone. route_state carries the same verdict as route, always as a string ("true", "false", "inconclusive"), for clients that cannot type a boolean-or-string field. contract_and_request_ok is the narrower combined verdict: true only when route is true AND your own declared request passed pre-flight, false when either is bad, and the string "not_assessed" when a term was never established (usually because you passed no intended_params). Test it with === true; contract_and_request_ok_excludes names the risk categories it is silent on. No success-rate field is returned, deliberately: Paddock observes settlements, not failed calls, so recency and frequency are reported instead. Pass attest: true to also issue a signed, publicly fetchable record of this verdict — returns an attestation id and a URL a third party can verify independently against Paddock's published key.
```

## Changes things (1)

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

### `check_payee`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Is this the seller's wallet, before my agent pays it? Fast payee check before an agent pays. Send the resource URL and the payment terms you are about to sign: payee wallet, network and amount. Paddock answers from its daily settlement record in one call, with no live probe, and returns pass, warn, fail or unknown. Only fail recommends blocking. Free without a key up to 25 checks a day, or 1000 a day with a free key. For a full check against the seller's live payment terms, use verify_before_pay. Past the free limits, $0.01 per call over x402.
```

## Only reads (11)

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

### `get_best_value_provider`

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

Description, as the server wrote it:

```untrusted-server-text
Which provider in this category should my agent pick? Paid - $0.02 per call via x402, or a Builder / Pro Agent key. Over MCP only, 1 free trial call/day is available without a key. Ranks a category by reliability (7-day share of probes that succeeded), reputation (unique buyers), and price, returning every input so the score can be checked. The composite formula is published in the route and in the docs, and Paddock does not sell positions in this ranking. Valid categories: llm, data, search, infra, content, markets, payments, comms (aliases accepted).
```

### `get_category_detail`

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

Description, as the server wrote it:

```untrusted-server-text
Who's selling in this category, and who's actually getting paid? Free key - a free pk_free_ key covers it against a shared 10 calls/day. Every service in a category with daily transactions, USDC volume, unique buyers, and reliability score, from the nightly snapshot. Valid categories: llm, data, search, infra, content, markets, payments, comms. Accepts common aliases (e.g. 'LLM inference' -> llm, 'scraping' -> data, 'trading' -> markets, 'defi' -> markets).
```

### `get_changes`

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

Description, as the server wrote it:

```untrusted-server-text
What changed since a date I name? Paid - $0.10 per call via x402, or a Builder / Pro Agent key. Over MCP only, 1 free trial call/day is available without a key. Diffs today against any snapshot up to 90 days back — new services, retired services, category share shifts, top movers, with the figures on both sides.
```

### `get_circular_signal`

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

Description, as the server wrote it:

```untrusted-server-text
Is this facilitator's volume real, or is it paying itself? Paid - $0.99 per call via x402, or a Builder / Pro Agent key. Over MCP only, 1 free trial call/day is available without a key. Wash/circular-settlement signal per facilitator: flagged clusters, flagged volume and share, self-funding percentage, detection date. Methodology public (v0.1). Patterns attach to the facilitator only — no seller wallet addresses, operator identity, or per-wallet rows are ever returned.
```

### `get_liveness`

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

Description, as the server wrote it:

```untrusted-server-text
Was this domain up at last night's probe, per someone who isn't the seller? Free key - a free pk_free_ key covers it against a shared 10 calls/day; $0.001 per call via x402 beyond it. Over MCP only, 1 free trial call/day is available without a key. Per-domain 7-day share of probes that succeeded, latency p50/p95, sample counts, and last-probe time — including domains with no payment history at all. Sourced from an independent third-party monitoring feed, captured NIGHTLY: this is a daily series, not a live probe — for a check taken at query time use verify_before_pay. up is 7-day share of probes that succeeded >= 0.95 across every probed endpoint on the domain.
```

### `get_market_summary`

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

Description, as the server wrote it:

```untrusted-server-text
How big is agent commerce today? (The citation number.) Keyless - no key, no payment, no rate limit. Returns daily transactions, USDC spend, unique buyer agents, live providers, and top categories by share. Each category's share_of_transactions is its share of CATEGORIZED (attributed) transactions — named categories only, NOT a share of the full-ecosystem daily_transactions total; only the top 6 are returned, so the shown shares sum to <100% by design.
```

### `get_niche_gaps`

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

Description, as the server wrote it:

```untrusted-server-text
Where is demand outrunning supply? Free key - a free pk_free_ key covers it against a shared 10 calls/day; $0.01 per call via x402 beyond it. Over MCP only, 1 free trial call/day is available without a key. Every category ranked by opportunity score (high volume, few providers), with concentration and an Open/Tightening/Consolidating/Mature signal, and the published thresholds behind that label.
```

### `get_provider_revenue`

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

Description, as the server wrote it:

```untrusted-server-text
Who earns the most, and how much of the market can that answer see? Paid - $0.99 per call via x402, or a Builder / Pro Agent key. Over MCP only, 1 free trial call/day is available without a key. Resolved by payTo wallet attribution, not by counting events. ATTRIBUTED universe only, never the full-ecosystem census: facilitator pass-through and circular-flagged wallets are excluded from the leaderboard; unresolved wallets are not dropped — they surface as one explicit unattributed row (transaction share only, no dollar figure exists for them). Also reports whether the recipient list was complete on every aggregated day, and flags (retroactive_exclusion_caveat) any day before 2026-07-28 where a wallet added to the exclusion lists afterward could not be retroactively re-checked.
```

### `get_report_data`

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

Description, as the server wrote it:

```untrusted-server-text
What are the numbers behind the monthly report? Paid - $0.99 per call via x402, or a Builder / Pro Agent key. Metadata is free. No free trial on this tool. The monthly State of Agent Commerce as structured JSON: every figure with its universe label and methodology version, plus trends, category breakdowns, protocol comparison and reliability. Any Agent Commerce Index (ACI) block is a retained historical print — the index is suspended (ADR 0006) and no new prints are computed. Free metadata (title, TOC, executive summary excerpt) is available without payment at /api/mcp/report-data.
```

### `get_token_metrics`

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

Description, as the server wrote it:

```untrusted-server-text
Is today's number a real move or ordinary noise? Free key - a free pk_free_ key covers it against a shared 10 calls/day; $0.01 per call via x402 beyond it. Over MCP only, 1 free trial call/day is available without a key. Paddock's own first-party series — the same chart data the public /charts page reads — queryable by metric and date range. Metrics: spend_share_over_time, daily_transactions, category_concentration, new_services, liveness_score, aci. The aci metric returns the Agent Commerce Index series, which is SUSPENDED (ADR 0006): existing prints are retained and served, no new prints are computed, so that series does not advance. This is Paddock's series, not token prices; third-party token market data is deliberately not resold here.
```

### `get_whale_activity`

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

Description, as the server wrote it:

```untrusted-server-text
Where did the large settlements go? Paid - $0.99 per call via x402, or a Builder / Pro Agent key. Over MCP only, 1 free trial call/day is available without a key. Large settlements over a window, aggregated by facilitator, category and size band, plus per-category mover counts. Size and where, never who — no individual seller identity is returned.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (1 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://paddock.finance/api/mcp/mcp: tools/list returned 13 tools to an anonymous client, including verify_before_pay (irreversible), check_payee (write)
