## Findings

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

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

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

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

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

description: "...Solana), providers requiring connected credentials (Bridge, Circle), and explicit capabili..."
```


## Can't be undone (1)

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

### `trace_payment`

- The name "trace_payment" says "payment": 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use this whenever you need to determine whether a supported stablecoin payment completed, failed, or is delayed — where the money currently is, who owns the next step, and what should happen next. Typical triggers: 'the recipient says the payment never arrived', 'this payout is stuck', 'did this transaction go through?'. Give it a Base transaction hash, Solana signature, Bridge transfer ID, Circle payment ID, or a Base/Solana wallet address (USDC). Trace correlates blockchain and provider evidence into one deterministic normalized state: completed/terminal flags, health, current stage and owner, an evidence-backed diagnosis code with a machine-readable suggested action and retry timing, and a knowledge model separating observed facts from inferences from what Trace cannot see (e.g. beneficiary bank credit — onchain finality never proves the recipient's bank credited funds; unknown never means failed). Public blockchain data works without authentication; provider-connected state requires an API key. If the user has no identifier, ask for a transaction hash, provider payment ID, or supported wallet address. Read-only: this tool never moves funds, retries payments, signs transactions, or guarantees beneficiary receipt — do not use it to send or swap anything. If a payment's state is unresolved, do NOT send a replacement payment; follow the returned warnings and suggested action instead.
```

## Only reads (2)

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

### `get_trace`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve an existing Trace payment trace by its trace_id (tr_...), including the stage timeline. Read-only. Same normalized representation as trace_payment.
```

### `list_supported_systems`

- The name "list_supported_systems" says "list": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
List what Trace supports and can do: assets (USDC), chains with public tracing (Base, Solana), providers requiring connected credentials (Bridge, Circle), and explicit capability flags (read-only; cannot send, retry, or sign). Call this when unsure whether a payment is in scope for trace_payment.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__trace__get_trace",
      "mcp__trace__list_supported_systems"
    ],
    "ask": [
      "mcp__trace__trace_payment"
    ],
    "deny": []
  }
}
