## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.

  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 623 tokens (~207/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `nara_search` (~316 tokens)

Keyword-search the US National Archives Catalog — the descriptions of the federal government's permanent records: agency files, military service and unit records, photographs, motion pictures, maps, treaties, presidential library holdings and artifacts. Returns each record's NAID, title, dates, archival hierarchy (record group → series → item) and whether scans are available online. AUTHORITATIVE for US federal archival holdings; PREFER OVER WEB SEARCH for "does the National Archives hold records about X", "NARA records on X". Example: nara_search({ query: "Apollo 11 moon", available_online: true, limit: 10 })

Input parameters:

- `available_online` (boolean): Only records that have digitised files attached (default false)
- `include_digital_objects` (boolean): Include the full digital-object list on every hit (default false — use nara_digital_objects for one record)
- `level_of_description` (string): Restrict to one level: "recordGroup", "collection", "series", "fileUnit" or "item"
- `limit` (number): Results per page (default 10, max 100)
- `page` (number): 1-based page number (default 1). NARA pages by page, not offset
- `query` (string, required): Keywords — a person, event, place, unit, agency or subject, e.g. "Apollo 11 moon"
- `record_group_number` (string): Restrict to one NARA record group, e.g. "255" (NASA)

### `nara_record` (~117 tokens)

Fetch one US National Archives Catalog record in full by its NAID (National Archives Identifier, the number in a catalog.archives.gov/id/ URL). Returns title, scope and content note, dates, access and use restrictions, the full archival hierarchy back to the record group, and the digital objects attached. Example: nara_record({ naid: "219756158" })

Input parameters:

- `naid` (string, required): National Archives Identifier, e.g. "219756158" — the number in a catalog.archives.gov/id/ URL

### `nara_digital_objects` (~134 tokens)

List the digitised files attached to one US National Archives Catalog record — scanned page images, PDFs, audio and video — with a direct, public-domain download URL, file type and size for each. Use after nara_search or nara_record when you want the actual document rather than its description. Example: nara_digital_objects({ naid: "219756158" })

Input parameters:

- `limit` (number): Maximum digital objects to return (default 50, max 500)
- `naid` (string, required): National Archives Identifier of the record whose scans you want, e.g. "219756158"
