Changes things 2Claude Code: ask
  • artifact_certifyDraw and certify a chart from the input in chart, using matching data, brand and theme.No findings

    Why it is in this group

    • 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
    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.

    Why it is in this group

    • 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
    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.

  • catalog_listRead components a page at a time.No findings

    Why it is in this group

    • The name "catalog_list" says "list": a word for reading.
    Description, as the server wrote it
    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_previewLook up a recorded screen by object, context and framework.No findings

    Why it is in this group

    • The name "design_preview" says "preview": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The description's first verb is "read": a word for reading.
    Description, as the server wrote it
    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.

    • title: Check Health
    • readOnlyHint: true
    • destructiveHint: false

  • object_registryRead objects from the pinned registry.No findings

    Why it is in this group

    • The description's first verb is "read": a word for reading.
    Description, as the server wrote it
    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_snapshotRead the registry summary: active objects and traits, loaded names, loader issues, etag and generatedAt.Reads text others writeNo findings

    Why it is in this group

    • The name "registry_snapshot" says "snapshot": a word for reading.

    What it can reach

    • untrusted-inputThe description's first sentence says "read" and "issue": it reads issues, which other people can write.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • title: Snapshot Registry
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • structured_data_fetchRead the tokens or manifest dataset.No findings

    Why it is in this group

    • The name "structured_data_fetch" says "fetch": a word for reading.
    Description, as the server wrote it
    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.

    • title: Fetch Structured Data
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • tool_schemaRead a shipped tool schema by name and kind (input or output).No findings

    Why it is in this group

    • The description's first verb is "read": a word for reading.
    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

  • WarnThe whole server

    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.

    Matched text

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

    What this check looks for

Install

Pinned to version 0.11.2. Values in angle brackets are yours to fill in.

claude mcp add --transport http foundry https://oods-foundry.com/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.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": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as foundry. Review it before you use it.
