## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__tangent__get_resource` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__tangent__browse_vertical` `mcp__tangent__get_person` |
| 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.


## Changes things (1)

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

### `related_resources`

- 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
Resources related to one resource, each with the reason (e.g. "shares Command Menu", "same maker"). Use it to follow tangents from a site you like. Example: {"slug": "stripe"}
```

## Only reads (9)

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

### `browse_vertical`

- The name "browse_vertical" says "browse": a word for reading.
- Tag untrusted-input: The name "browse_vertical" says "browse": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
The newest resources in one section: inspiration, components, motion, build, visuals, tools or learn. Use it to browse without a query, with the same filters as search_resources and cursor paging. Example: {"vertical": "components", "technology": "react", "limit": 20}
```

### `find_inspiration`

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

Description, as the server wrote it:

```untrusted-server-text
Turns a design brief into a short list of references (default 8, at most 10), each with `why` it fits: the pattern, style, category, technology or platform it shares with the brief, or how search matched it (e.g. "similar meaning"). It reads the brief against Tangent's taxonomy and synonyms and combines that with search; no AI calls. Use it when someone describes a screen or product they are about to design. `interpreted_as` shows how the brief was read. Example: {"brief": "onboarding for a fintech app, playful but clean", "platform": "mobile"}
```

### `get_pattern`

- The name "get_pattern" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
One UI pattern: its definition, its best examples, related patterns and the technologies the examples use. Use it before designing that pattern. Example: {"slug": "empty-state", "limit": 8}
```

### `get_person`

- The name "get_person" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
One person's profile: role, bio, website, social links, studios, what their site is built with (confirmed technologies) and their work on Tangent. Set include_image to also get a small preview of their site. Example: {"slug": "emil-kowalski"}
```

### `get_resource`

- The name "get_resource" says "get": a word for reading.
- Tag private-data: The description's first sentence says "note": it reads notes.

Description, as the server wrote it:

```untrusted-server-text
Everything Tangent knows about one resource: descriptions, taxonomy, editorial notes, the people behind it, and its related resources (tangents) with reasons. Use it to go deeper on a search pick. Set include_image to also get a small screenshot. Example: {"slug": "linear"}
```

### `list_patterns`

- The name "list_patterns" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Every UI and interaction pattern resources are filed under (Command Menu, Onboarding, Empty State and more), with example counts. Use it to pick a slug for get_pattern. Example: {}
```

### `list_people`

- The name "list_people" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Designers and design engineers in the catalogue, featured first, then by name, with optional technology and role filters and cursor paging. Use search_people to find someone by name or focus. Example: {"role": "design engineer", "technology": "nextjs", "limit": 20}
```

### `search_people`

- The name "search_people" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find designers and design engineers by name, role, focus or stack, ranked, with optional technology and role filters. Example: {"query": "motion", "role": "design engineer"}
```

### `search_resources`

- The name "search_resources" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Ranked search over Tangent's catalogue of design and design-engineering resources (sites, products, component libraries, tools, articles). Use it when you know roughly what you want; narrow with vertical, category, technology, type, pricing or open_source, and page with cursor. For a whole brief, use find_inspiration. Example: {"query": "command menu", "technology": "react", "limit": 5}
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__tangent__find_inspiration",
      "mcp__tangent__search_resources",
      "mcp__tangent__browse_vertical",
      "mcp__tangent__get_resource",
      "mcp__tangent__list_patterns",
      "mcp__tangent__get_pattern",
      "mcp__tangent__search_people",
      "mcp__tangent__list_people",
      "mcp__tangent__get_person"
    ],
    "ask": [
      "mcp__tangent__related_resources"
    ],
    "deny": []
  }
}
```

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

- `mcp__tangent__browse_vertical`: untrusted-input
- `mcp__tangent__get_resource`: private-data
- `mcp__tangent__get_person`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:47:22.245Z, unchanged since 2026-10-22T14:47:22.245Z. 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` |

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

https://tangent.directory/api/mcp: tools/list returned 10 tools to an anonymous client, including related_resources (write)
