**4 tools: 2 change things and 2 only read.**

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

| Only reads | read | 2 | 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__lookupd__get_entry` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__lookupd__get_entry` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `health`

- 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
Probe status of an entry: whether its remote endpoint is up, needs a login (auth_required), is down or dead, with 7-day uptime, median latency, tool count and the last probe. Stdio-only servers are not_probeable.
```

### `report_outcome`

- 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
After a task used an MCP server, report once per server whether it worked: servers found via lookupd in this conversation and servers already installed alike. `entry` is the registry name; for an installed server, get it from get_entry with the server's url or package (skip the report if there is no entry). `success` is required. Structured fields only (entry, capability_tag, success, latency_bucket, runtime, error_class); never task text, prompts or paths. Rankings improve from these reports.
```

## Only reads (2)

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

### `find_capability`

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

Description, as the server wrote it:

```untrusted-server-text
Find MCP servers that provide a capability for a task. Pass a short capability phrase (e.g. "read Linear issues"), not the user's full request. Results are ranked provisionally (no outcome evidence yet) and each includes an install snippet for the given runtime. Lookups are free.
```

### `get_entry`

- The name "get_entry" says "get": a word for reading.
- Tag untrusted-input: The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Full details for one entry: raw server.json, install snippets for the runtime, lookupd metadata. Pass the registry name (e.g. io.github.acme/linear-mcp), or, for a server already in your MCP config, its remote url or its npm/PyPI package; that finds the registry name to use with report_outcome. When several entries launch the same url or package, `matches` lists them all, most likely first.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__lookupd__find_capability"
    ],
    "ask": [
      "mcp__lookupd__get_entry",
      "mcp__lookupd__health",
      "mcp__lookupd__report_outcome"
    ],
    "deny": []
  }
}
```

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

- `mcp__lookupd__get_entry`: untrusted-input, outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-04T02:18:55.440Z, unchanged since 2026-11-04T02:18:55.440Z. 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 | `2` |
| 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` |

- **warn** 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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.lookupd.com/mcp: tools/list returned 4 tools to an anonymous client, including health (write), report_outcome (write)
```
