# Connect Pomeroy to Claude Desktop

> Pomeroy opens its Claude extension and Claude Desktop asks to install it. No file to find, no Terminal. Then Claude Desktop can reach Mail, Calendar, Reminders, Notes, Contacts, Messages, Maps, Weather and Shortcuts on your Mac, each app behind its own switch.

**Claude Desktop** is Anthropic's Mac app, and it works with Pomeroy. Pomeroy
sets itself up in it with one click. Claude Desktop can then read the apps you
switched on, and no others.

<Info>
  **What Set up does.** Pomeroy opens the Claude extension it ships with, and
  Claude Desktop shows its own install prompt. Approve it. Nothing is written to
  Claude's configuration file.
</Info>

## Set up

<Steps>
  <Step title="Install Pomeroy and switch on your apps">
    [Download Pomeroy](https://pomeroy.app/download), drag it into Applications
    and open it. Switch on the apps you want Claude Desktop to reach. Everything
    starts off, and macOS asks you to approve each app as you switch it on. [The
    full walkthrough](/docs/getting-started/installation).
  </Step>

  <Step title="Install Claude Desktop, if you have not">
    Pomeroy lists the assistants it finds on this Mac, so install [Claude
    Desktop](https://claude.com/download) first if it is not there. Returning to
    Pomeroy's window re-checks.
  </Step>

  <Step title="Press Set up">
    In Pomeroy's **Assistants** pane, find Claude Desktop 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.
  </Step>

  <Step title="Pick it up">
    **Quit Claude Desktop and open it again.** It reads its server list only at
    launch.
  </Step>

  <Step title="Ask something">
    In Claude Desktop, ask what is on your calendar today. The answer comes from
    your Mac.
  </Step>
</Steps>

## The configuration

There is none to paste. Claude Desktop's route is the bundled extension: Pomeroy
opens the file and Claude Desktop installs it, so nothing is written to a
configuration file of yours.
[What the extension is](/docs/configuration/stdio#the-claude-desktop-extension).

## Over the local endpoint

Not available. Claude Desktop's connectors are brokered through Anthropic's
cloud, so an address on your Mac's own loopback is not reachable from them. The
extension is the route, and it needs no address.

[The two ways in](/docs/configuration/overview).

## How to check it worked

In Claude Desktop, open **Settings › Extensions** and Pomeroy is listed. In a
new chat, the tools menu under the message box shows Pomeroy's tools, one set
for each app you switched on.

If the tools are missing, the cause is almost always that the assistant has not
re-read its server list.
[Troubleshooting](/docs/getting-started/troubleshooting#an-assistant-cannot-see-the-tools).

## Worth knowing about Claude Desktop

The extension is Anthropic's preferred route for a local server, and the one
Pomeroy has shipped since its first release. Claude Desktop reads a new
extension only after a full quit and reopen.

## What it can reach

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