Agentic Autofill for Claude always fails with "relayUnavailable"

I'm trying to use the 1Password + Claude integration (Agentic Autofill), but every credential request from Claude fails with "relayUnavailable". The local relay between the 1Password browser extension and the desktop app never seems to come up.

Environment

- macOS

- 1Password for Mac 8.12.28 (81228025)

- 1Password browser extension 8.12.28.25 (81228025), STABLE channel, Chrome

- Claude browser extension installed and connected

- Developer Integrations: "Integrate with 1Password CLI" is on (used for a separate secret-reference workflow in .env files). "Integrate with 1Password SDKs" is currently off.

What works

- Pairing completes successfully. I get the "Authorize Claude with 1Password" dialog and approve it with Touch ID.

What fails

- Every credential request returns transport_error / relayUnavailable.

- This happens in both the Claude desktop app (Cowork) and Claude Code.

Already ruled out

- Swapped the extension from the Nightly channel to STABLE - no change.

- Restarted Chrome, the 1Password app, and the Mac - no change.

- Re-did the Claude / 1Password pairing - no change.

- Both app and extension meet the documented 8.12.28+ requirement.

- Tried "Integrate with 1Password SDKs" both enabled and disabled - no difference.

- Support's AI chatbot suggested "op plugin inspect/clear/init claude", but that returns "unknown plugin: claude" - the CLI shell plugins are unrelated to this issue.

Has anyone got Agentic Autofill working, or knows what else could stop the extension / desktop app relay from coming up?

Same issues here:

Fair. The integration didn't work — every request_credentials call came back with a transport error (reason: decode), which isn't even one of the documented failure modes I'm told to expect (unreachable app, outdated app, not connected). So it wasn't the usual "1Password isn't open" case; something in the actual handoff broke, and it broke silently enough that I couldn't route around it.

Hi @Sa371 and @bdruth, I’m sorry to hear that you’re running into issues with Agentic Autofill.

I’d like to have our support team investigate further. Could you create and share a diagnostics report from the 1Password desktop app: Send a diagnostics report (Mac)

Attach the diagnostics to an email message addressed to: support@1password.com

Thanks @1P_Gem! I've emailed the diagnostics to support@1password.com

Support ID: 683359

Note: the files were too large to attach, so I shared them via a Google Drive link in the email instead. Diagnostics from both the desktop app and the browser extension are included.
