## Quality 73/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-03-26; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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: 71 (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
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: search-parts (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); normalize-pn (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get-substitutes (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 433 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`: 7 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: 5, about 433 tokens to load them all
- tool set hash: 5996344d84fa27c039214e05d2ce608c
- tools last changed: 2026-10-20T02:55:10.771Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.partstable/partstable.svg)](https://protogrid.dev/servers/com.partstable/partstable)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

## Tools (5)

- `get-part`: Get the canonical record for a part: identity, manufacturer, description, category, lifecycle, and government classification (NSN/FSC) when present. Sourced from the PartsTable canonical read model.
- `get-substitutes`: Find substitute / equivalent / cross-referenced part numbers in the PartsTable cross-reference graph (2,001,002 cross-references, measured 2026-10-18).
- `normalize-pn`: Normalize an IT hardware part number into its canonical form. Handles HPE (B21/001/spare), Dell (400-XXXX, DP/N), and IBM/Lenovo (FRU) formats. Critical for deduplication and accurate lookups.
- `search-parts`: Look up a batch of part numbers (max 25) against the PartsTable catalog. Returns per-part identity summary and whether each exists.
- `validate-pn`: Validate a part number and check whether it exists in the PartsTable catalog (26,182,530 distinct part numbers, measured 2026-10-20), from government, OEM, and commercial authority sources. Returns structural validity and catalog existence.
