Available tools 2

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

alternative
find_alternative
Cross-reference a wire-harness component part number (connectors, terminals, seals, cable protection) against the XrefBase equivalence graph. Results are grouped by how strong the relationship is, and the groups are not interchangeable: `verified_replacements` are corroborated drop-in or manufacturer-superseded parts; `functional_equivalents` do the same job but need engineering review; `same_series` and `variants` are the same family in a different configuration and are NOT substitutes; `mates_with` is the counterpart connector the part plugs into, which is specifically not a substitute for it. Every claim carries a confidence level and, where one exists, a public source URL.
manufacturer
find_manufacturer
Search the Harness Atlas directory of wire-harness and cable-assembly manufacturers. Filter by country, industry served, process capability, or name. Returns listed manufacturer profiles (location, website, industries, capabilities).

Harness Atlas — questions

Answers built from our own checks of this server.

What can Harness Atlas do?
It exposes 2 tools, read directly from the server on our last check. Among them: find_alternative, find_manufacturer. 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 Harness Atlas 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 473 ms. The bar chart above shows every period we have measured.
How do I connect Harness Atlas?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Harness Atlas need an API key?
No. Harness Atlas completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Harness Atlas?
It answers our handshake in 473 ms on average, which is faster than 24% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
