What is apple-notes-mcp CLAUDE.md?

A set of instructions for an MCP server that lets an AI assistant search, read, create, update, and manage Apple Notes using natural-language requests.

Use it when developing, checking, or testing the Apple Notes MCP server.

It gives a coding agent the project layout, data flow, commands, and testing rules, including which test command to use.

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	$0.01062	$0.01062
Opus 5.5	$0.00425	$0.00425
Sonnet 5.5	$0.00212	$0.00212
Haiku 4.5	$0.00106	$0.00106

Security

Grade A, and why

apple-notes-mcp CLAUDE.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 2mo 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.

Project Overview

MCP server for Apple Notes with semantic search and CRUD operations. Claude searches, reads, creates, updates, and manages Apple Notes through natural language.

Commands

bun run start      # Start MCP server
bun run setup      # Interactive setup wizard
bun run dev        # Watch mode
bun run check      # Type check
bun run test       # Run tests (uses vitest, NOT bun test)
bun run test:watch # Watch mode for tests

Important: Always use bun run test (vitest), never bun test (Bun's test runner is incompatible).

Architecture

Data Flow

User Query → MCP Server → Search Module → Embeddings → LanceDB → Results
                ↓
           Apple Notes ← JXA (JavaScript for Automation)

Entry Point

src/index.ts - Main MCP server with stdio transport for Claude Code

Core Modules

Search Pipeline (src/search/)

index.ts - Legacy hybrid search using Reciprocal Rank Fusion (RRF)
indexer.ts - Full and incremental indexing with indexed_at timestamp tracking
chunk-indexer.ts - Chunk-based indexing for Parent Document Retriever pattern
chunk-search.ts - Chunk search with note deduplication (keeps best chunk per note)

Embedding Providers (src/embeddings/)

Auto-detection: checks OPENROUTER_API_KEY to choose provider
local.ts - HuggingFace Transformers with Xenova/multilingual-e5-small
openrouter.ts - Cloud API via OpenRouter

Vector Store (src/db/lancedb.ts)

Singleton LanceDBStore with FTS index on content
Storage path: ~/.apple-notes-mcp/data
Schema: NoteRecord with vector, content, indexed_at fields

Apple Notes Access (src/notes/)

read.ts - JXA queries via run-jxa
resolve.ts - Note title disambiguation logic
conversion.ts - HTML→Markdown via Turndown
crud.ts - Create, update, delete, move operations (respects READONLY_MODE)
tables.ts - Table HTML parsing and cell editing

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.
