Any other AI app that supports MCP

Send this to your AI agent. It adds PinPin to its own settings.

Add an MCP server named "pinpin" to your settings. It is a local stdio server: the command is /Applications/PinPin.app/Contents/MacOS/pinpin-mcp with no arguments and no environment variables. When it is added, remind me to restart you or start a new session, because PinPin only works in sessions started after it’s added.

App can’t edit its own settings? Add PinPin by hand

Add this to the mcpServers section of the app’s settings file, then restart the app. If the app asks field by field, choose a local (stdio) server named pinpin with the command below and no arguments.

{
  "mcpServers": {
    "pinpin": {
      "command": "/Applications/PinPin.app/Contents/MacOS/pinpin-mcp",
      "args": []
    }
  }
}

Check it worked

Troubleshooting

My AI says it can’t find PinPin

PinPin must be in your Applications folder. Move it there, then restart your AI app.

Your AI says PinPin isn’t reachable

Open PinPin and keep your Mac awake. Web AIs reach your notes through your Mac.

It’s connected, but can’t read or change anything

Check that AI access isn’t Off: PinPin menu bar icon › AI Access, or PinPin Settings › AI. Read only lets your AI read but not change your notes.
