**9 tools: 2 change things and 7 only read.**

## 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__foundry__registry_snapshot` |
| 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 (2)

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

### `artifact_certify`

- 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
Draw and certify a chart from the input in chart, using matching data, brand and theme. Returns the same result as viz_render: hashes, warnings and the certification verdict, including accessibility equivalence, determinism, contrast and accuracy. Optional chart.output fields add SVG, the accessible table and narrative, or the normalized specification. A verdict can be conformant false; each pillar explains its result.
```

### `viz_render`

- 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
Draw and certify a chart from inline data. Provide chartType and encodings with rows, a pattern with its own data, or an intent to recommend a tabular chart. Brand and theme apply to drawing and certification. The compact reply contains hashes, warnings and certification; output.svg adds the SVG drawing, includeA11y adds the table and narrative, and includeNormalizedSpec adds its specification. Request SVG when a displayed chart is needed. Up to 500 rows; optional outputs still share the 100,000-character reply bound. artifact_certify returns the same drawing and checks for an input in chart.
```

## Only reads (7)

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

### `catalog_list`

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

Description, as the server wrote it:

```untrusted-server-text
Read components a page at a time. category, trait, context and status filter the list; status describes the HTML renderer. detail is brief by default, or full when filtering; summary includes tags, contexts, regions and traits. Brief and summary allow up to 200 entries; full clamps pageSize to 10 and reports the adjustment. totalCount, hasMore and nextPage describe pagination. object_registry reads objects instead.
```

### `design_preview`

- The name "design_preview" says "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a recorded screen by object, context and framework. Returns its running screen URL, content hash, brand and theme. No new screen is generated. object_registry reads the definition behind the screen. Set reproduce true when the command and calls used to generate it are requested.
```

### `health_check`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the running service status, pinned version, registry counts, built brands, themes, token scopes and retained proof summaries. Uptime and latency are current process measurements; host paths are omitted. includeChangelog adds the DSL changelog, and sinceVersion keeps entries after that version. catalog_list and object_registry read the definitions behind the counts.
```

### `object_registry`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read objects from the pinned registry. action list returns names, traits and field counts; domain, trait and maturity filter them, and includeInternal adds internal objects. action show requires name and returns its composed definition; context narrows view extensions. registry_snapshot provides an overview; design_preview looks up recorded screens.
```

### `registry_snapshot`

- The name "registry_snapshot" says "snapshot": a word for reading.
- Tag untrusted-input: The description's first sentence says "read" and "issue": it reads issues, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Read the registry summary: active objects and traits, loaded names, loader issues, etag and generatedAt. detail full includes definitions; names narrows them. includeInternal adds internal objects. Replies larger than 100,000 characters are refused with their size. object_registry reads one composed object; catalog_list reads components.
```

### `structured_data_fetch`

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

Description, as the server wrote it:

```untrusted-server-text
Read the tokens or manifest dataset. Full data is the default; detail summary returns section counts and the first page call. page reads lossless JSON Pointer entries; pageSize defaults to 10, at most 100, also bounded by size. meta.next continues and meta.full requests full data. includePayload false returns metadata; listVersions lists dates, version selects one, and ifNoneMatch returns matched true without unchanged payload. catalog_list reads components.
```

### `tool_schema`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read a shipped tool schema by name and kind (input or output). Returns its JSON Schema, package-relative file, recorded file hash and source URL. tools/list describes this endpoint’s narrower accepted inputs; the full schema may describe operations outside the hosted tools.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__foundry__health_check",
      "mcp__foundry__catalog_list",
      "mcp__foundry__object_registry",
      "mcp__foundry__registry_snapshot",
      "mcp__foundry__structured_data_fetch",
      "mcp__foundry__design_preview",
      "mcp__foundry__tool_schema"
    ],
    "ask": [
      "mcp__foundry__viz_render",
      "mcp__foundry__artifact_certify"
    ],
    "deny": []
  }
}
```

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

- `mcp__foundry__registry_snapshot`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:37:39.937Z, unchanged since 2026-10-22T14:37:39.937Z. 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` |

| 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://oods-foundry.com/mcp: tools/list returned 9 tools to an anonymous client, including viz_render (write), artifact_certify (write)
