ical

apple-mail-cli

A Claude Code plugin marketplace with two read-only macOS automation tools. Both target macOS 13+ Apple Silicon (arm64) only and communicate with Apple apps via Apple Events — no credentials, no network access, no API keys.

Plugin	Binary	What it does
apple-mail	amail	Read and manage Mail.app — accounts, mailboxes, messages, rules, send
ical	aical	Read Calendar.app — calendars and events with date-range filtering

Platform: macOS 13+ · Apple Silicon (arm64) only

Install via Claude Code

Add this marketplace to Claude Code, then install the plugin(s) you want:

/plugin marketplace add trodemaster/apple-mail-cli
/plugin install apple-mail@amail-plugins
/plugin install ical@amail-plugins

Each plugin ships a pre-built, ad-hoc-signed arm64 binary in its bin/ directory. The plugin system adds it to PATH automatically — no manual setup required. On first use, macOS will prompt for automation permission — click Allow.

Build from source

Requires Go 1.21+ and macOS Apple Silicon.

make              # build, sign (ad-hoc), and install both binaries to $GOBIN
make skill        # cross-compile both arm64 plugin binaries and sign them
make skill-mail   # apple-mail plugin only
make skill-ical   # ical plugin only

amail commands

Accounts

amail accounts

Lists all configured email accounts with name, addresses, and type.

Mailboxes

amail mailboxes [--account "Account Name"]

Lists all mailboxes with unread and total message counts. Filter to one account with --account.

Messages

# List messages in a mailbox
amail messages list --account "iCloud" --mailbox "INBOX" [--limit 25] [--unread] [--summary]

# Read a full message by ID
amail messages read <message-id>

# Search across mailboxes
amail messages search [--from "addr"] [--subject "text"] [--query "text"] \
  [--account "Name"] [--mailbox "Name"] [--limit 25] [--summary]

• --summary fetches message bodies and shows a 2-line plain-text preview (HTML stripped, word-wrapped in Go)
• --from and --subject use Mail.app's indexed search — fast even on mailboxes with thousands of messages
• --query searches subject, sender, and body — slower; use --mailbox to scope it
• Without --mailbox, search automatically skips Trash, Junk, Sent, Drafts, and All Mail

Send

amail send --to "[email protected]" --subject "Subject" --body "Body text" \
  [--to "[email protected]"] \
  [--cc "[email protected]"] \
  [--bcc "[email protected]"] \
  [--attachment "/absolute/path/to/file"]

--to, --cc, --bcc, and --attachment are all repeatable.

Rules

# List all filter rules with conditions and actions
amail rules list

# Add a condition to an existing rule
amail rules add-condition --rule "services" --expression "example.com" \
  [--type from] [--qualifier ends-with]

# Create a new rule that moves matching messages to a mailbox
amail rules create --name "services2" --move "Services" --expression "example.com" \
  [--account "Account Name"] [--type from] [--qualifier ends-with]

# Apply a single rule to a mailbox using fast indexed queries (recommended)
amail rules apply --rule "services" [--mailbox INBOX] [--account "Account Name"]

# Apply all enabled rules (batched; slower on large mailboxes)
amail rules apply [--mailbox INBOX] [--batch-size 500]

Condition types: from to cc subject any-recipient body account Qualifiers: contains not-contains begins-with ends-with equals

Rule scale: Mail.app's GUI degrades beyond ~80 conditions per rule. When a rule is full, create a numbered sibling (services2, services3, etc.).

Schema

amail schema

Emits the full JSON spec of every command, subcommand, flag, type, and default. Useful for agents and scripting.

aical commands

Calendars

aical calendars

Lists all calendars with id, name, writable flag, and description.

Events

# Events for the next 7 days (default)
aical events

# Just today
aical events --today

# Specific date range
aical events --from 2026-05-01 --to 2026-05-31

# Relative window
aical events --days 14

# Filter to one calendar
aical events --calendar "Work" --days 30 [--limit 100]

Flags: --calendar NAME, --from YYYY-MM-DD, --to YYYY-MM-DD, --today, --days N (default 7), --limit N (default 50), --format json, --pretty

Output

All commands (amail and aical) print a human-readable table by default. When piped or when --format json is passed, output is a JSON envelope:

{
  "ok": true,
  "data": <T>,
  "error": { "code": "...", "message": "..." } | null,
  "meta": { "command": "...", "timestamp": "..." }
}

Use --pretty for formatted JSON.
