## Findings

- **info** The word "credentials" in `discover_agent` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...rns agent capabilities only; NO payment credentials. Example: discover_agent('pay:acme.user..."
```

- **info** The word "credentials" in `get_agent_registration_info` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...Read-only — registration itself is the credential-gated POST this tool points at. Example..."
```


## Changes things (1)

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

### `check_alias_available`

- 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
Check whether a pay: alias can still be claimed. Returns exactly one of three states: 'available' (free to register), 'taken' (already registered), or 'reserved' (protected namespace). When available, also returns the number of founding spots remaining. Public — no API key required. Read-only: this never reserves or registers the name. Example: check_alias_available('pay:acme.user').
```

## Only reads (5)

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

### `discover_agent`

- The description's first verb is "get": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Get the AP2/A2A agent-commerce block for a pay: address — the DNS of Money equivalent of an A2A agent-card lookup. Use this during agent discovery before initiating a mandate flow. Returns agent capabilities only; NO payment credentials. Example: discover_agent('pay:acme.user').
```

### `get_agent_registration_info`

- The name "get_agent_registration_info" says "get": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Learn how to self-register a FREE pay:agent.<label> alias for your agent. Returns the registration endpoint, the AgentAuthorityCredential verifiable-presentation requirements (intent binding + domain), the rate limit, and the Merkle anchor-proof endpoint. Read-only — registration itself is the credential-gated POST this tool points at. Example: get_agent_registration_info().
```

### `get_payment_requirements`

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

Description, as the server wrote it:

```untrusted-server-text
Get x402 PaymentRequirements for paying a pay: alias. Returns the 402 `accepts` block (scheme, network, payTo, asset, amount, invoiceId) an x402 agent needs to construct and submit the payment. currency='XRP' settles on the XRP Ledger (amount in drops); currency='USDC' settles USDC on Algorand via the GoPlausible facilitator (amount in atomic micro-USDC, feePayer in `extra`). The deterministic resolver chooses the rail; this tool never moves money. Example: get_payment_requirements('pay:acme.user', amount='1.5').
```

### `get_payment_status`

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

Description, as the server wrote it:

```untrusted-server-text
Check whether a payment you already attempted was recorded, BEFORE you retry and risk spending twice. Pass the request_key you sent as the Idempotency-Key header on the paid request. Returns state 'settled' (we hold a receipt — do NOT pay again) or 'not_found' (we have no record — retrying is safe). Use this when a paid call timed out or its response was lost: on rails where the facilitator broadcasts, you never learn the transaction hash unless our response reaches you, so this key is the only thing that can answer. The key is a bearer secret — whoever presents it gets the receipt.
```

### `resolve_alias`

- The name "resolve_alias" says "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve a human-readable financial alias (pay: address) to payment endpoints and routing metadata. Call this before initiating any payment to a pay: address. Returns the preferred rail, fallback endpoints, an ISO 20022 hint, and a compliance signal. Anonymous calls return status only; a free API key (no credit card) unlocks the endpoint set — which rails and currencies the alias accepts — via POST /api/v1/access-requests. You do NOT need a key to pay: get_payment_requirements returns a payable address to any caller. Example: resolve_alias('pay:acme.user').
```
