## 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)

Scored 2026-10-18.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised build step with no custom scripting around it.
  - 1 of 32 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to ianderso/gov-gazetteer-mcp).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 7 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1397 tokens (~232/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (6)

### `gov_search` (~265 tokens)

Find places in GOV by name: id, names, types, coordinates and current parents.

Matching is literal: whole words and word beginnings, ignoring case and
accents (Lubeck finds Lübeck), never spelling variants. German, Polish and
old spellings (Cöslin/Köslin/Koszalin) each need their own call, and a
zero covers only the spelling tried. GOV answers at most 500 objects; use
\`within` or `place_type` to narrow. Then call gov_place_at_date with the
event's year.

Input parameters:

- `limit` (integer): Most candidates returned (1-100).
- `name` (string, required): A place name, e.g. 'Quedlinburg'. One spelling per call.
- `place_type` (string): Keep these types: ids, GOV's German names ('Dorf', 'Kirchspiel', 'Standesamt'), or settlement, civil, parish, standesamt, court; comma-separated.
- `refresh` (boolean): Ask GOV again instead of the 7-day cache.
- `within` (string): Only places GOV records inside this object at any date: a GOV id of a Kreis, province or state, e.g. 'adm_133152'.

### `gov_object` (~177 tokens)

Read one GOV object in full: every name, type and parent, each with its dates.

Names carry languages; part-of, located-in and represents relations are
grouped by parent, current first, with dates and GOV's source ids. Notes
are volunteers' text. For one year's chain use gov_place_at_date.

Input parameters:

- `children` (boolean): Also list the objects GOV records inside this one (a parish's villages).
- `gov_id` (string, required): A GOV id (e.g. 'QUEURGJO51NT', 'object_289891'), its GOV page address, or an external id GOV records as 'system:ref' (e.g. 'geonames:2851465', 'wikidata:Q40623').
- `refresh` (boolean): Ask GOV again instead of the 30-day cache.

### `gov_place_at_date` (~206 tokens)

A place as it was in one year: its name and the civil chain above it to the state.

Each level gives its type and the link's dates. Links GOV leaves undated,
or attests only in another year, are marked. A place that changed Kreis
or state within the year shows both. Reads up to 40 GOV objects the first
time, then from the cache.

Input parameters:

- `gov_id` (string, required): A GOV id (e.g. 'QUEURGJO51NT', 'object_289891'), its GOV page address, or an external id GOV records as 'system:ref' (e.g. 'geonames:2851465', 'wikidata:Q40623').
- `language` (string): Preferred language of names, as GOV codes it: 'deu', or 'pol' for a place under Polish rule then.
- `year` (integer, required): The year of the event, e.g. 1885.

### `gov_registers` (~236 tokens)

Which parish and Standesamt kept a place's registers in one year, as GOV records it.

Looks at the place and every level above it in that year; each lead says
which level carries the link, with dates. Gives the bodies above each
parish (whose archive may hold the books) and the local court. Says
plainly when GOV records no parish or Standesamt. A link is a lead: confirm
it in the register's own heading.

Input parameters:

- `confession` (string): Keep parishes of one confession: protestant, lutheran, reformed, catholic, old catholic or jewish (or GOV's codes ev, lu, lt, rf, rk, ak).
- `gov_id` (string, required): A GOV id (e.g. 'QUEURGJO51NT', 'object_289891'), its GOV page address, or an external id GOV records as 'system:ref' (e.g. 'geonames:2851465', 'wikidata:Q40623').
- `year` (integer, required): The year of the event, e.g. 1885.

### `gov_enclosures` (~215 tokens)

Every dated enclosure of a place and of each civil place above it, for a place tree.

For each place: its names and types with dates, a suggested Gramps place
type, and `enclosed_by`, one entry per parent with its periods, current
first, each with a `gramps_date` ('from 1871-01-01 to 1937-03-31').
Parishes, courts and registry offices of the place come separately.
Narrow with from_year/to_year; at most 40 places.

Input parameters:

- `from_year`: Only enclosures that held in or after this year.
- `gov_id` (string, required): A GOV id (e.g. 'QUEURGJO51NT', 'object_289891'), its GOV page address, or an external id GOV records as 'system:ref' (e.g. 'geonames:2851465', 'wikidata:Q40623').
- `to_year`: Only enclosures that held in or before this year.

### `cache_status` (~28 tokens)

Report this session's requests to GOV, by operation, and cache use. Makes no network call.

### What tools does the GOV Historical Gazetteer MCP server expose?

GOV Historical Gazetteer exposes 6 tools: gov_search, gov_object, gov_place_at_date, gov_registers, gov_enclosures, cache_status. Their descriptions and schemas cost roughly 1,127 tokens of context every time the server is loaded.

### Is the GOV Historical Gazetteer MCP server still maintained?

GOV Historical Gazetteer is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
