**5 tools: 1 do something that can't be undone, 3 change things and 1 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

| Can't be undone | irreversible | 1 | ask |
| Changes things | write | 3 | ask |
| Only reads | read | 1 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__onramperx__create_onramp_session` `mcp__onramperx__create_swap` `mcp__onramperx__get_route_quote` `mcp__onramperx__provision_wallet` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__onramperx__create_swap` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `create_swap`

- The name "create_swap" says "create": a word for a change.
- The input addresses people (input.recipient): what it sends cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.recipient): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Use this to swap any token on any chain into USDC on Base via Relay. Returns a headless deposit address (no signing) or an on-chain intent. App fees accrue on swaps.
```

## Changes things (3)

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

### `check_swap`

- 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
Use this to check a Relay swap's status by requestId and confirm app-fee collection (appFees vs paidAppFees).
```

### `create_onramp_session`

- The name "create_onramp_session" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Use this when a US user wants to buy USDC on Base with a card / Apple Pay / Google Pay. Returns a payment link a HUMAN must physically tap (fiat legs cannot be programmatically triggered); a human is notified. US-only guest checkout, <= $500/week.
```

### `provision_wallet`

- The description's first verb is "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Use this to create a gasless, non-custodial CDP Embedded Wallet address on Base (TEE keys, user-exportable) to receive routed value.
```

## Only reads (1)

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

### `get_route_quote`

- The name "get_route_quote" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Use this when a human or agent wants the best non-custodial way to move value between fiat and crypto (or crypto to crypto). Returns ranked rails with fees, ETA, KYC burden, limits, and reasoning.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__onramperx__get_route_quote"
    ],
    "ask": [
      "mcp__onramperx__create_swap",
      "mcp__onramperx__check_swap",
      "mcp__onramperx__create_onramp_session",
      "mcp__onramperx__provision_wallet"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__onramperx__get_route_quote`: untrusted-input
- `mcp__onramperx__create_swap`: untrusted-input, outbound
- `mcp__onramperx__create_onramp_session`: untrusted-input
- `mcp__onramperx__provision_wallet`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:36:45.583Z, unchanged since 2026-10-22T14:36:45.583Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `https://router.mudko.com/.well-known/oauth-protected-resource` |
| Authorization servers | `https://router.mudko.com` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `yes` |
| Client ID metadata documents | `no` |

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (1 irreversible, 3 write). Whether a call also works without credentials was not tested: tools are never called.

https://router.mudko.com/api/mcp: tools/list returned 5 tools to an anonymous client, including create_swap (irreversible), check_swap (write), create_onramp_session (write), provision_wallet (write)
