    How to connect

    How to connect Harness Atlas to Claude

    The server address to paste into Claude settings:

    https://harnessatlas.com/api/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect Harness Atlas to ChatGPT

    The server address to paste into ChatGPT settings:

    https://harnessatlas.com/api/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

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is, and the groups are not interchangeable: `verified_replacements` are corroborated drop-in or manufacturer-superseded parts; `functional_equivalents` do the same job but need engineering review; `same_series` and `variants` are the same family in a different configuration and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