Use it to create, view, edit, and delete reminders and lists on a Mac.
Why use it?
It lets an agent manage Reminders directly instead of requiring separate manual changes in the Reminders app. It only works on macOS.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

apple-reminders-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Apple Reminders MCP Server

Identity

MCP server for Apple Reminders on macOS. Exposes Reminders.app via native EventKit bindings (pyobjc) — no AppleScript, no binary installs.

Tech Stack: Python 3.11+, FastMCP, pyobjc-framework-EventKit, uv

Module Map

Module Path Purpose
server src/apple_reminders_mcp/server.py All MCP tools — reminder and list CRUD

Build & Run

# Install dependencies

# Run server locally
uv run apple-reminders-mcp

# Run directly from GitHub (no clone)
uvx --from git+https://github.com/yazilim-vip/apple-reminders-mcp apple-reminders-mcp

Project Rules

  • macOS only — EventKit requires macOS with Reminders.app
  • Version bump required — CI blocks PRs that don't bump version in pyproject.toml
  • Single-file server — all tools live in server.py; split only when complexity demands it
  • No AppleScript — use pyobjc EventKit bindings exclusively

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
