Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

cross_reference Read-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_family

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.

read-only

Argument	Type	Description
family*	string

Input schema (JSON)

{
  "type": "object",
  "title": "describe_familyArguments",
  "required": [
    "family"
  ],
  "properties": {
    "family": {
      "type": "string",
      "title": "Family"
    }
  }
}

list_families

Every component family in the TAS catalogue, with how many parts it holds and whether it has a deterministic selector. Start here.

read-only

No arguments.

Input schema (JSON)

{
  "type": "object",
  "title": "list_familiesArguments",
  "properties": {}
}

part_details

One part by MPN: its extracted specs and, optionally, the full TAS catalogue record behind them (datasheet URL, mechanical drawing, provenance).

read-only

Argument	Type	Description
mpn*	string
family*	string
manufacturer	any
include_record	boolean

recommend_parts

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.

Argument	Type	Description
family*	string
options	any
max_results	integer

    }
  }
}

search_parts

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_distribution

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.
