What is apple-mail-mcp AGENTS.md?

Repository guidance describes an MCP server that lets Claude work with Apple Mail through AppleScript on macOS. AppleScript is Apple's automation language for controlling applications, and the document lists tools for finding, reading, changing, and drafting email.

Use it when developing or testing mailbox searches, message updates, drafts, and other Apple Mail operations on macOS.

It gives the agent the project's commands, testing rules, and Apple Mail-specific constraints before it changes the integration.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01552	$0.01552
Opus 5.5	$0.00621	$0.00621
Sonnet 5.5	$0.00310	$0.00310
Haiku 4.5	$0.00155	$0.00155

Security

Grade A, and why

apple-mail-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 1mo 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.

Apple Mail MCP Server

An MCP server bridging Claude and Apple Mail via AppleScript on macOS.

Stack: Python 3.10+, FastMCP, AppleScript (via osascript) Version: v0.10.2 | Tests: 1612 unit / 29 e2e / 62 integration | Coverage: 92%

Commands

make test                  # Unit tests (~1s, mocked AppleScript)
make test-integration      # Real Mail.app tests (requires test account)
make test-e2e              # End-to-end MCP tool tests
make lint                  # Ruff linting
make format                # Ruff formatting
make typecheck             # Mypy strict mode
make check-all             # All checks (lint, typecheck, test, complexity, version-sync, parity)
make coverage              # Coverage report
./scripts/check_complexity.sh          # Cyclomatic complexity check
./scripts/check_client_server_parity.sh  # Verify all connector methods are exposed
./scripts/check_version_sync.sh        # Version consistency across files

Running the server: uv run python -m apple_mail_mcp.server or via Claude Desktop config.

API Surface (35 MCP tools)

Core: list_mailboxes, search_messages, get_messages, update_message Drafts lifecycle (#134): create_draft, update_draft, delete_draft Mailbox CRUD: create_mailbox, update_mailbox (rename + move via IMAP), delete_mailbox (IMAP-only) Attachments & Management: save_attachments, get_attachment_content (#250, inline read), delete_messages Discovery & Rules: list_accounts, list_rules, get_thread, create_rule, update_rule, delete_rule Templates: list_templates, get_template, save_template, delete_template, render_template

Core Principles

TDD always — RED/GREEN/REFACTOR. Tests before implementation.
Backend + frontend together — Every feature touches mail_connector.py AND server.py. Verify with check_client_server_parity.sh.
Sanitize everything twice — All user input: sanitize_input() then escape_applescript_string() before AppleScript.
Structured responses — Every tool returns {"success": bool, ...}. Errors include error and error_type.
Security checklist per feature — see docs/guides/SECURITY_CHECKLIST.md for the canonical reference (5 concerns: input sanitization, AppleScript escaping, path-traversal-safe name validation, rate limiting, audit logging). Don't duplicate guidance here; link out instead.
If you touched AppleScript, write integration tests — Unit tests mock _run_applescript() and CANNOT catch AppleScript bugs.

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.
