# Troubleshooting and feedback

> Check common connection problems and send useful feedback about Gatetrix Access, d0, or MTS.

## An agent cannot see a tool

1. Keep the relevant Mac app open.
2. Check that agent access and the selected MCP transport are enabled.
3. Confirm the credential belongs to the intended profile or connection.
4. Check the resource grants and allowed operations for that identity.
5. After upgrading, refresh the agent's MCP connection. In MTS, start a new
   conversation if new tools are missing from an older conversation.

A saved connection may still need sign-in, tool review, or an explicit grant
before it can be used.

## Setup works, but an operation is denied

In Access, check [profiles, grants, and approvals](/access/permissions).
In d0, check both the dashboard's trusted version and its
[runtime permissions](/d0/runtime). In MTS, check the connection's project scope
and allowed actions.

If a write returned an uncertain result, inspect its status before trying again.
Repeating the request can create a second action in the connected service.

## Send useful feedback

Use the app's feedback action, where available, or email
[hello@gatetrix.ai](mailto:hello@gatetrix.ai).

* The product, app version, and macOS version.
* What you wanted to do and the steps you took.
* What happened and what you expected instead.
* The error message, with private information removed.

Do not include API keys, passwords, MCP tokens, or private customer data.
