remindctl-mcp

MCP server for Apple Reminders via remindctl.

Lets any MCP-compatible AI assistant (Amazon Quick, Claude Desktop, etc.) read and write your Apple Reminders through the standard Model Context Protocol.

Requirements

• macOS 14+ (Sonoma or later)

• remindctl installed (brew install steipete/tap/remindctl)

• Python 3.11+

• uv (recommended) or pip

Setup (Amazon Quick)

1. Clone & install dependencies

git clone https://github.com/ebi-yade/remindctl-mcp.git
cd ./remindctl-mcp
uv venv
uv pip install mcp

2. Register as MCP server

Open Settings → Capabilities → Connectors → + Add MCP server and configure:

Replace /path/to/ with the actual location (e.g. /Users/you/remindctl-mcp/).

3. Grant Reminders permission

macOS controls Reminders access via TCC. Permission is granted to the host app that spawns the MCP server process (e.g. Amazon Quick), not to python or remindctl directly.

1. Ask the assistant to call reminders_authorize

2. A macOS dialog will appear — click OK

3. Verify with reminders_status → should show "authorized": true

TCC Troubleshooting

If any tool returns "Reminders access denied", the fix is always the same:

# 1. Reset permission to trigger a fresh prompt
tccutil reset Reminders <bundle_id>

# For Amazon Quick:
tccutil reset Reminders com.amazon.QuickWork.mac

Then ask the assistant to call reminders_authorize again and click OK on the dialog.

Why this happens: macOS may revoke TCC grants after OS updates, or the user may have accidentally denied the prompt. tccutil reset clears the decision so the dialog can appear again.

Tools

How it works

MCP Host (Amazon Quick, Claude, etc.)
  ↕ stdio (JSON-RPC)
remindctl-mcp (this server)
  ↕ subprocess
remindctl CLI
  ↕ EventKit API
Apple Reminders (syncs via iCloud)

The server is a thin wrapper: it translates MCP tool calls into remindctl CLI invocations and returns JSON output. No data is stored or cached — all state lives in Apple Reminders.

Other MCP hosts

This server uses stdio transport and works with any MCP client. For Claude Desktop, add to claude_desktop_config.json:

{
  "mcpServers": {
    "remindctl": {
      "command": "/path/to/remindctl-mcp/.venv/bin/python",
      "args": ["/path/to/remindctl-mcp/server.py"]
    }
  }
}
