**3 tools: 1 can delete or cancel things and 2 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 1 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 0 | ask |
| Only reads | read | 2 | allow |

## Exfil surface

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

| 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__canli__run_tool` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `run_tool`

- The name "run_tool" says "run": a word for a change.
- The server marks it destructive (destructiveHint: true).
- 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
Run one tool ({name, arguments}) or several in one call ({calls: [...]}). Any argument can be {"$file": "path.csv", "column": "close"} (or "columns": [...] / "all") instead of pasted numbers. {"$result": i, "path": "close"} passes batch call i's output into a later call; every result also has a ref ("r1", "r2", ...) that later run_tool calls can pass the same way, {"$result": "r1", "path": "close"}, so data never needs to be copied.
```

## Only reads (2)

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

### `describe_tool`

- The name "describe_tool" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get one tool's full description and exact input JSON Schema before calling run_tool.
```

### `find_tool`

- The name "find_tool" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the 311 finance tools (packs: quant, validation, fundamentals, research, backtest, markets) by what you need, e.g. "deflated sharpe", "black scholes greeks", "revenue as of 2019". Returns names, packs, argument signatures and one-line descriptions, best first.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__canli__find_tool",
      "mcp__canli__describe_tool"
    ],
    "ask": [],
    "deny": [
      "mcp__canli__run_tool"
    ]
  }
}
```

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

- `mcp__canli__run_tool`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:56:28.475Z, unchanged since 2026-10-22T14:56:28.475Z. 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 | `1` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **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 1 tool that changes things (1 destructive). Whether a call also works without credentials was not tested: tools are never called.

https://canlicapital.com/mcp/canli: tools/list returned 3 tools to an anonymous client, including run_tool (destructive)
