## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `export_audit_bundle`

- 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
Export a JWS-signed audit-trail bundle of scoring decisions for a wallet.

MCP equivalent of GET /v1/audit/export. Compliance artifact for EU AI Act
Article 12 logging / NYDFS certification / debanking-defense. Because audit
data covers arbitrary wallets, this tool is operator-gated: pass the
operator's ``admin_token`` (checked against ``REVETTR_ADMIN_TOKEN``).
Disabled when that env var is unset. Note: ``admin_token`` travels in the
MCP request payload, so operators should treat MCP transcripts/logs as
sensitive. Verify the returned ``bundle_jws``
against /.well-known/jwks.json; the schema is in docs/audit-trail-export.md.
```

### `score_counterparty`

- 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
Score a counterparty before sending money. Returns risk score 0-100.

Accepts EVM wallets (0x...), Stellar wallets (G...), domains, IPs, and company names.
```

## Only reads (1)

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

### `verify_issuer`

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

Description, as the server wrote it:

```untrusted-server-text
Get an advisory risk verdict for a validated MCP issuer (iss).

Attach this at your MCP `iss` validation step: identity is your job, this
adds risk. Returns the same signed RiskCheckResult as POST /v1/iss-verdict.
Advisory and non-blocking — you decide based on the tier.
```

## Claude Code permissions
