## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `write_receipt`

- The name "write_receipt" says "write": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Hubs only (x-hub-key): lodge one receipt for a gate decision — the hash on the Confidential Ledger, the receipt kept and served by decision_id. Idempotent on decision_id.
```

## Only reads (1)

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

### `get_receipt`

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

Description, as the server wrote it:

```untrusted-server-text
The signed receipt of one gate decision on a GSC hub, by decision_id: what was cleared, for whom, under which rule, when — with the hub signature and the ledger transaction id. No caller data, no PII, no amounts.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `rco-a2a`:

```json
{
  "permissions": {
    "allow": [
      "mcp__rco-a2a__get_receipt"
    ],
    "ask": [
      "mcp__rco-a2a__write_receipt"
    ],
    "deny": []
  }
}
```
