## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The input carries an amount (input.policy.max_cost.amount) and a currency, so it moves money.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "intentfence_checkout" says "checkout": a word for a change.
```

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

```untrusted-server-text
The input schema at properties.project_name.description mentions "credentials".

inputSchema.properties.project_name.description: "...blic-safe project label. Do not include credentials or secrets."
```

- **info** The word "credentials" in `intentfence_x402_readiness` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

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

description: "...$0.002 USDC on Base). Makes one bounded credential-free request to a public HTTPS target,..."
```


## Can't be undone (1)

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

### `intentfence_authorize_action`

- The input carries an amount (input.policy.max_cost.amount) and a currency, so it moves money.
- 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
Authorize an exact agent action against an explicit allowlist, spend ceiling, retention ceiling, and optional action-bound approval. Returns a five-minute ES256 receipt and never executes the downstream action. Callers must verify the receipt and fail closed if the action changes.
```

## Changes things (9)

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

### `intentfence_agent_risk_scan`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Free metadata-only scan of caller-supplied MCP tool definitions for missing schemas, unsafe annotations, approval binding, and cost boundaries. Does not execute tools or certify security.
```

### `intentfence_checkout`

- The name "intentfence_checkout" says "checkout": a word for a change.
- 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
Free machine checkout builder. Select a paid IntentFence outcome and receive the exact endpoint, validated request, USDC cap, shell-safe Agentic Wallet argv, MCP tool call, and opt-in local auto-payment budget. It never signs or initiates payment.
```

### `intentfence_policy_pack`

- 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Paid self-service integration pack (1 USDC on Base). Generates a runtime-specific TypeScript guard, signed action and policy receipt, negative test vectors, and a fail-closed deployment checklist for Cloudflare Agents, Coinbase AgentKit, or an MCP gateway. No meeting or account is required.
```

### `intentfence_preflight`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Free declared-input preview with no signed receipt, authorization proof, or enforcement guarantee. Returns safe_to_proceed, needs_review, or denied.
```

### `intentfence_us_cpi`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Paid official U.S. CPI and core CPI data ($0.001 USDC on Base), retrieved from the Bureau of Labor Statistics with a six-hour edge cache and returned with an ES256 provenance receipt. Optionally request a YYYY-MM period.
```

### `intentfence_verified_preflight`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Paid production preflight ($0.005 USDC on Base). Settles through x402 and returns a signed ES256 audit receipt plus settlement metadata.
```

### `intentfence_wallet_risk`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Paid AML/KYT wallet screening ($0.002 USDC on Base) before sending funds or approving a transaction. Checks live Base activity plus GoPlus sanctions, phishing, mixer, money-laundering, dark-web, blacklist, and related counterparty-risk flags, then returns a five-minute ES256 receipt. A low-risk result is not proof of identity, ownership, authorization, or future behavior.
```

### `intentfence_x402_assessment`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Paid assessment ($0.005 USDC on Base). Forward the exact base64 or base64url PAYMENT-REQUIRED header observed by the caller. IntentFence validates the quote, canonical Base USDC asset, price ceiling, payee allowlist, timeout, and resource binding without contacting the target, then returns a short-lived ES256 receipt bound to the quote hash. Supply allowed_payees for safe_to_proceed; omission yields needs_review.
```

### `intentfence_x402_readiness`

- 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Paid live endpoint check ($0.002 USDC on Base). Makes one bounded credential-free request to a public HTTPS target, blocks private networks and redirects, never pays the target, validates the returned x402 challenge, and returns a signed five-minute receipt.
```
