## Quality 91/100 (strong)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 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: 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`: 7 of 7 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 2,152 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no 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: 7, about 2,152 tokens to load them all
- tool set hash: 71af11e35cc79f2f50764b9f8921099b
- badge: [![protogrid quality](https://protogrid.dev/badge/io.whatic/datasheets.svg)](https://protogrid.dev/servers/io.whatic/datasheets)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (7)

- `compare_parts`: Relative price tier, stock posture, and library class for a set of IC part
numbers (a ranking from a distributor snapshot, not a live quote).
- `find_parts`: Shortlist IC part numbers by parametric spec constraints, ranked by how many constraints each part satisfies, then by headroom past those thresholds, and spread across device families. Each constraint is {canonical, op: gte|lte|eq|range, value, unit?}. Returns per-constraint pass/fail/unknown, plus `matched` (parts meeting EVERY constraint), `ranked` (all parts scored, partial matches included) and `returned` (parts in this response). `truncated` means some qualifying parts are not on this page. When `matched` is 0 every result is a partial match. `canonical` MUST be one of the exact (case-sensitive) names enumerated in this tool's inputSchema, also readable as the whatic://parametric/canonicals resource.
- `get_image`: Fetch datasheet figure images (PNG/JPEG) for opaque `ref` tokens obtained
from search/lookup/get_segments. Returns each image plus its caption/description/page
metadata. Only `type='image'` segments have image data; a ref that is not one comes
back as an error record whose `available_images` lists the document's figures nearest
that ref's page and section, closest first.
- `get_segments`: Expand opaque `ref` tokens (from search/lookup) into full datasheet segment
content.
- `get_specs`: Read canonical extracted specs (min/typ/max, unit, conditions) for known
IC part numbers from a pre-extracted parametric index — not from datasheet text.
This is the cheapest and most precise source for numeric parameters where it has
coverage. Optionally restrict to specific canonical parameter names.
A part absent from `results` (with a "No specs found" warning) means no index
coverage, not that the datasheet lacks the parameter — fall back to `lookup`
for that part.
- `lookup`: One-shot spec/section retrieval: full content of the most relevant datasheet
segments for one or more parts (fuses search+get_segments). Already groups results per
part (via `parts`), so prefer `lookup` over `search` when you know the part(s).
- `search`: Search the datasheet corpus; returns hit records (metadata + snippet, each
with an opaque `ref`). Pass a ref list to `get_segments` for full content.
If you already know the part number(s), prefer `lookup` — it fuses this search
with `get_segments` in one call and groups full content per part. Use `search`
when the part is unknown, or to triage snippets before pulling full content.
For part-specific queries, pass scope='device:<MPN>' (e.g. scope='device:NE5532')
to restrict hits to that part and avoid cross-part contamination.
