You need an Apple silicon Mac running macOS 13 or newer and an agent application that supports MCP. Access uses a separate background core; its window can be closed while the app stays running. Read Interfaces for the difference between closing the window and quitting.
1

Install Access

Download Gatetrix Access, open the disk image, and install the app in Applications. Open Access.
2

Create an agent profile

Open Configuration and create an Agent Profile for this agent or task. Give it a recognizable name, such as “Research assistant.” Select that profile before editing its connections and permissions.
3

Enable an MCP transport

Under Access Channels → MCP, enable MCP and the transport your client uses. Use stdio for a local process connection, or HTTP bound to 127.0.0.1 for a client on this Mac. Use the endpoint shown in Access.
4

Create the credential and connect your client

Open MCP Credentials for the selected profile and create a credential. Use the app’s generated client configuration for your chosen transport. Put the credential in your MCP client’s credential configuration, not in a conversation or project source file. Reconnect the client after configuration.
5

Add one useful data source

Open Connectors or Folders for the profile and grant the source you want this agent to use. For an online service, follow Set up a connector with an agent. Start with the smallest read scope that answers your question.
6

Verify access

Ask the agent to discover its tools and perform one bounded read from the approved source. Check that the result is useful and inspect Audit Log. If approval is required, decide in Access and have the agent retrieve the saved result.

What success looks like

The agent can discover and use the intended tool through its profile. It has not needed the connected service’s API key in chat. The activity appears in Access under the correct profile. If tools are missing, check the selected profile, credential, transport, and connection grants. An upstream MCP server connection also needs tool discovery and review. See Troubleshooting for the next checks.
