Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 1493 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name harness-atlas.

  • Pass
    Lists tools

    tools/list returned 3 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 1099 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1454 ms over 2 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    2 of 2 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Pass
    Stable tool list

    No tool was removed and no required parameter was added in the last 30 days.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    9 of 11 parameters have a description (82%). The bar is 80%.

  • Fail
    Safety hints

    3 tools set neither readOnlyHint nor destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass

Capabilities

Tools 3

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is, and the groups are not interchangeable: `verified_replacements` are corroborated drop-in or manufacturer-superseded parts; `functional_equivalents` do the same job but need engineering review; `same_series` and `variants` are the same family in a different configuration and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.

Discovered
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). Manufacturers only: makers of production and test equipment (cut & strip, crimping, harness testers, ...) are not returned here; use search_equipment_suppliers for them.

Discovered
search_equipment_suppliers

Search the production and test equipment suppliers listed on Harness Atlas: makers of the machines and test systems wire harnesses are built and checked with (cut & strip, crimping presses and applicators, ultrasonic welding, twisting, seal loading, taping, tube processing, wire marking, electrical harness testing, crimp quality, assembly boards). These are equipment vendors, not harness manufacturers; use find_manufacturer for manufacturers. Filter by equipment category, country, or name. `country` matches the vendor's HQ country or any listed location (service centre, sales office, demo centre, representative). Returns each vendor's categories and its listed locations, each with the public source URL it was taken from.
