Troubleshooting

Most problems come from one of four places: the connector in your AI app, your sign-in, the agent on your computer, or the CAD program. Work down this page.

The connector will not add

  • Check the URL is exactly https://mcp.cadmcp.ai/mcp with nothing before or after it.
  • Claude Free allows one custom connector. Remove another custom connector, or use a paid Claude plan.
  • On Claude Team or Enterprise, an owner may need to add CADMCP.AI for the organisation first.

Sign-in fails or keeps coming back

  • Sign in with your CADMCP.AI account, not your Claude or OpenAI account.
  • Check that your plan is active on your account page.
  • Forgot your password? Reset it.
  • Remove the connector from your AI app, add it again and sign in once more.

“No computer connected”

  • Is the computer on and awake, and is the agent running in the tray?
  • Does the agent say it is connected? If not, check your internet connection and any company proxy or firewall that blocks outgoing connections.
  • Is Pause AI access switched on in the agent?
  • If you paired more than one computer, is this one marked as active in Your CADMCP.AI?

The AI cannot see my model

  • Open the CAD program and the document you want to work on.
  • In SOLIDWORKS, check that our add-in is switched on under Tools, Add-ins.
  • Planning questions work without a model open; reading and changes do not.

A change is waiting

That is expected: every change waits for a person. Look for the approval card in the CAD program (in SOLIDWORKS, our add-in’s task pane). Requests expire if nobody answers them; ask again if one has expired.

A change was refused

  • The document changed on disk after the request was made, or a different document is now active. Ask again with the right document active.
  • The request asked for something that is never allowed, such as saving over an existing file.
  • Change requests are switched off on that computer.

Codex says a tool timed out

A slow read in a large model can take longer than Codex waits. Try a narrower question (one body, one feature), or ask again. Change requests are not affected: they wait on the approval card.

Still stuck?

Email info@cadmcp.ai with the time it happened, your AI app (Claude or Codex), your CAD program and the message you saw. Please never send passwords, card numbers or confidential CAD files.
