Nothing serious here today

Today is the operative word: we check Kelvin — power electronics components every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

cross

cross_reference

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

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.

families

list_families

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

part

part_details

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

parts

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.

recommend

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.

spec

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.

Kelvin — power electronics components — questions

Answers built from our own checks of this server.

What can Kelvin — power electronics components do?

It exposes 7 tools, read directly from the server on our last check. Among them: cross_reference, describe_family, list_families, part_details, recommend_parts, search_parts and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Kelvin — power electronics components working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 191 ms. The bar chart above shows every period we have measured.

How do I connect Kelvin — power electronics components?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Kelvin — power electronics components need an API key?

No. Kelvin — power electronics components completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Kelvin — power electronics components?

It answers our handshake in 191 ms on average, which is faster than 73% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
