## 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__svgrid__list_examples` |
| 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.

### `check_svgrid_code`

- 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
Verify SvGrid code BEFORE handing it to the user. Checks the source against the real exported surface of the current version - <SvGrid> prop names, ColumnDef keys, grid API methods, importable symbols and theme files - plus Svelte 5 runes rules, and returns line-numbered diagnostics with the exact replacement for each. Run it on every file you write that uses SvGrid, fix what it reports, and run it again.
```

## Only reads (5)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the full text behind a search result. Pass a doc slug ("help/columns/column-definitions") or a demo id prefixed with "demo:" ("demo:11-stock-market").
```

### `get_api_reference`

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

Description, as the server wrote it:

```untrusted-server-text
The SvGrid public API grouped by category (components, headless, scheduler, data ops, export, row models, features, virtualization, accessibility, utilities), for the version this server tracks.
```

### `get_example_source`

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

Description, as the server wrote it:

```untrusted-server-text
Return the full .svelte source of one demo by id (e.g. "11-stock-market") - working code to copy, not a summary of it.
```

### `list_examples`

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

Description, as the server wrote it:

```untrusted-server-text
Browse the SvGrid demo catalogue: id, title, category and a one-line blurb. Call with no arguments for the category index, then filter with `query` or `category`, then read one with get_example_source.
```

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
Ranked full-text search across the SvGrid documentation and demo catalogue. Returns the best pages first with an excerpt and an id you pass to `fetch`. Use this before writing SvGrid code so the API names come from the docs rather than from memory.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__svgrid__search",
      "mcp__svgrid__fetch",
      "mcp__svgrid__list_examples",
      "mcp__svgrid__get_example_source",
      "mcp__svgrid__get_api_reference"
    ],
    "ask": [
      "mcp__svgrid__check_svgrid_code"
    ],
    "deny": []
  }
}
```

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

- `mcp__svgrid__list_examples`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:41:51.998Z, unchanged since 2026-10-22T14:41:51.998Z. 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://mcp.svgrid.com/mcp: tools/list returned 6 tools to an anonymous client, including check_svgrid_code (write)
```
