Search 500+ wire-harness & cable-assembly manufacturers by country, industry, and capability.
The publisher's own server: Red Atlas Api
Remote MCP server for sourcing wire harnesses and cable assemblies: search manufacturers and cross-reference component part numbers for alternatives.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.pawel-kowalczyk%2Fharness-atlas/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}A remote Model Context Protocol server for sourcing wire harnesses and cable assemblies. It answers two questions an agent cannot answer from general web knowledge: who manufactures this, and what part can replace this one.
Hosted, public, no API key, nothing to install.
Listed in the official MCP registry as io.github.pawel-kowalczyk/harness-atlas.
The endpoint moved to
harnessatlas.comon 2026-08-24 (manifest v0.2.0). The previous Supabase URL still works and is not being retired, so existing clients keep functioning — but this is the address to use.
Wire-harness sourcing data is scattered across trade directories, PDF catalogues and manufacturer sites that general-purpose models summarise badly and cite unreliably. Harness Atlas is a structured directory of the sector with per-field provenance, exposed over MCP so an agent can query it directly instead of guessing.
find_manufacturerSearch the directory of wire-harness and cable-assembly manufacturers. All parameters optional.
Returns name, HQ country and city, website, industries served, plant count, capabilities and a profile URL.
find_alternativeCross-reference a component part number — connectors, terminals, seals, cable protection —
against the XrefBase equivalence graph. part_number is required; manufacturer is optional and
disambiguates an MPN that exists under several makers (aliases such as TE and H+S are
accepted). Punctuation and case are normalised, so 1-967616-1 and 19676161 both match.
Results are grouped by relationship strength, and the groups are not interchangeable:
Every claim carries a confidence level and, where one exists, a public source URL. The grouping is the point: a tool that returns one flat list of "alternatives" invites an agent to propose a mating connector as a replacement part.

Straight JSON-RPC, to try it without a client:
verified_replacements is the only group that should be read as a substitution
recommendation, and even that warrants engineering review for a safety-relevant application.Harness Atlas is a directory and reference service. It does not broker, quote or transact, and listing is not endorsement.
The server runs as a hosted endpoint; its implementation is not open source. This repository is the public home for the server: its registry manifest, documentation and examples.
server.json is a mirror published for registry discovery. The canonical copy lives with the
implementation and is what mcp-publisher publishes — if the two ever disagree, the version in
the official registry is authoritative.

The licence does not extend to the Harness Atlas directory data returned by the hosted endpoint. That data remains proprietary and is offered for use through the endpoint itself.

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).
namelimitcountryindustrycapabilityCross-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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
