## Trust

- hygiene: 80
- liveness: 100
- freshness: 85
- provenance: 55
- drivers: +dns-namespace +website +reachable +uptime-100% ~updated-61d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 90/100 (strong)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 11 of 11 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,838 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 9 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 11, about 1,838 tokens to load them all
- tool set hash: cf8344cd4f5a1a8df910f71392f7e93c
- tools last changed: 2026-10-19T11:20:42.239Z
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.partsgraph/catalog.svg)](https://protogrid.dev/servers/ai.partsgraph/catalog)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (11)

- `build_bom`: Composes a complete BOM for a reference build — quantities, dated indicative prices, per-line rationale, a compatibility verdict for the chosen set, and a CSV export. Override any role with choices.
- `check_compatibility`: Evaluates a part set against the build's engineering constraints — supply windows, stall vs peak current, shaft/wheel fit, interfaces, solar chain — with a reasoned verdict per check. Every number cited is a corroborated attribute.
- `compare_parts`: Aligned attribute-by-attribute comparison of two catalogue parts. Absence means the sources did not state a value — never that the part lacks the property.
- `fetch`: Fetch the full provenance-backed record for a search result id as a citable document. Alias of get_part shaped to the search/fetch connector contract.
- `get_part`: The complete canonical record for one part: every attribute with its provenance (source, page, verbatim quote, file hash), vendors with dated indicative prices, and datasheet links.
- `get_provenance`: The receipt behind a stated value: the verbatim source quote, the page, the extraction method, and the sha-256 of the exact file it was read from — plus a ready-made citation line. Omit code for every attribute's receipt.
- `list_builds`: The catalogue's reference builds (robot, weather station, plant waterer) with their roles and candidate parts — the starting point for build_bom.
- `list_categories`: Every category in the catalogue with its part count.
- `search`: Search the Partsgraph demo catalogue. Returns result ids for fetch. Alias of search_parts shaped to the search/fetch connector contract.
- `search_parts`: Full-text search over the demo catalogue's provenance-backed part records. Filter by category, build or role. Every attribute returned was corroborated against the manufacturer datasheet or vendor page.
- `view_bom`: Composes the BOM for a reference build and renders it as an interactive view in clients that support MCP Apps. Same data as build_bom.
