A server's first observation is its baseline; later probes record what changes.
Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

cross_referenceread-only | Find substitutes for a part by MPN — the deterministic, program-only cross-reference the Kelvin web app runs: pre-gate the catalogue at the ranker's own reject edges, then score every candidate on value, ratings, footprint and mount type. No LLM judgement. An original whose own specs are incomplete can never yield a clean 'recommended'. |
describe_familyread-only | The exact field names one family can be filtered, sorted and bucketed on, and the designRequirements keys its selector reads. Call this before search_parts on an unfamiliar family rather than guessing field names. |
list_familiesread-only | Every component family in the TAS catalogue, with how many parts it holds and whether it has a deterministic selector. Start here. |
part_detailsread-only | One part by MPN: its extracted specs and, optionally, the full TAS catalogue record behind them (datasheet URL, mechanical drawing, provenance). |
recommend_partsread-only | Kelvin's deterministic selector: rank real parts against a designRequirements block and return the candidates with the margins that ranked them. Same authority Kirchhoff and Heaviside select through — no LLM judgement, reproducible. |
search_partsread-only | Parametric search over one family: numeric ranges, categorical values, MPN substring and manufacturer, with optional facet counts. This is the catalogue question — 'what parts do we have that ...' — and needs no converter design. |
spec_distributionread-only | How one numeric spec is distributed across a filtered slice of a family — bucket counts (log or linear) plus how many parts state the value at all. Answers 'what is available' questions that a top-N list cannot. |
Schemas: list_tools.
