Connect Pomeroy to Cline

Pomeroy writes one entry to the settings file every Cline surface shares. No restart needed. Then Cline can reach Mail, Calendar, Reminders, Notes, Contacts, Messages, Maps, Weather and Shortcuts on your Mac, each app behind its own switch.

Cline is the coding agent inside VS Code and JetBrains, and it works with Pomeroy. Pomeroy sets itself up in it with one click. Cline can then read the apps you switched on, and no others.

What Set up does. Pomeroy adds pomeroy to Cline’s settings file, leaving every other server in it untouched. Cline watches that file and reconnects the servers that changed.

Set up

1. Install Pomeroy and switch on your apps

   Download Pomeroy, drag it into Applications and open it. Switch on the apps you want Cline to reach. Everything starts off, and macOS asks you to approve each app as you switch it on. The full walkthrough.

2. Install Cline, if you have not

   Pomeroy lists the assistants it finds on this Mac, so install Cline first if it is not there. Returning to Pomeroy’s window re-checks.

3. Press Set up

   In Pomeroy’s Assistants pane, find Cline and press Set up. It is safe to press any number of times. It writes the same thing every time, and it never disturbs another server already there.

4. Pick it up

   No restart needed. Cline picks the server up on its own.

5. Ask something

   In Cline, ask what is on your calendar today. The answer comes from your Mac.

The configuration

You do not need this. Set up writes it for you. It is here so you can see what Pomeroy adds, check it by hand, or set up a second Mac without opening the panel.

Goes in ~/.cline/data/settings/cline_mcp_settings.json:

{
  "mcpServers": {
    "pomeroy": {
      "autoApprove": [],
      "command": "/Applications/Pomeroy.app/Contents/MacOS/pomeroy-mcp",
      "disabled": false
    }
  }
}

The command is a single absolute path with no arguments, and it lives inside Pomeroy’s app bundle, so an update never changes it. What the pipe is.

Over the local endpoint

Cline can also reach Pomeroy over the HTTP endpoint instead of the pipe. Use it only for a copy running somewhere that cannot start a program on this Mac, such as a container or a remote workspace. Switch the local address on in Pomeroy’s Connections pane first.

Goes in ~/.cline/data/settings/cline_mcp_settings.json:

{
  "mcpServers": {
    "pomeroy": {
      "autoApprove": [],
      "disabled": false,
      "headers": {
        "Authorization": "Bearer <the key Pomeroy generates>"
      },
      "type": "streamableHttp",
      "url": "http://127.0.0.1:13579/mcp"
    }
  }
}

Pomeroy writes the real token in place of the placeholder when it can reach this assistant’s settings. Otherwise you can read the token under Connections.

How to check it worked

In Cline’s MCP Servers view, pomeroy is listed and connected. In the terminal, cline config mcp shows the same entry.

If the tools are missing, the cause is almost always that the assistant has not re-read its server list. Troubleshooting.

Worth knowing about Cline

Cline’s editor extensions, its JetBrains plugin and its command-line tool all read this one file, so setting it up once covers every place you use Cline.

What it can reach

Only the apps you switched on, and only through the tools Pomeroy publishes. Cline cannot send mail, send a message, delete anything or edit a contact, because no tool does those things.

What Pomeroy can do

Ten apps, 27 tools, and every refusal.

Permissions

What each toggle grants, and what macOS asks you for.

Other assistants

All 24, and what to do if yours is not listed.
