apple-health-mcp-server 0.1.4

Probably the most complete Apple Health MCP server

apple-health-mcp-server

Probably the most complete Apple Health MCP server.

Read this in English / 日本語.

apple-health-mcp-server exposes the contents of your Apple Health export (export.xml plus the ECG CSV and GPX route files Apple ships alongside it) to any Model Context Protocol client — including Claude Desktop — through 17 read-oriented tools backed by a local DuckDB database.

Features

• Comprehensive ingestion. Imports Record, Workout (with WorkoutEvent, WorkoutStatistics, WorkoutRoute, and WorkoutMetadataEntry), ActivitySummary, Correlation, Me, ExportDate, ECG voltage samples, and GPX route points. Categorical state-of-mind entries (iOS 17+) land in a dedicated table.
• All data stays local — no external transmission. The importer reads files from disk, the server speaks MCP over stdio (HTTP is opt-in), and the only network artefact is whatever the client itself decides to send.
• DuckDB-backed. Re-imports are idempotent thanks to deterministic deduplication; ad-hoc analysis through run_custom_query runs at native DuckDB speed.
• Time-zone aware. GPX route timestamps are aligned to each parent workout's local offset so joins against XML-derived rows are clean.
• Cross-platform. Tested on Ubuntu, macOS, and Windows against Python 3.12 / 3.13 / 3.14.
• 100% branch-tested. Every release gates on full coverage with pytest --cov-branch --cov-fail-under=100.

Installation

The recommended entry point is uvx, which fetches a one-shot virtualenv on demand and never pollutes the system Python:

uvx apple-health-mcp-server --help

Claude Desktop

Edit claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: Claude Desktop is not yet released on Linux; use Claude Code below instead.

{
  "mcpServers": {
    "apple-health": {
      "command": "uvx",
      "args": ["apple-health-mcp-server", "serve"]
    }
  }
}

Then fully quit Claude Desktop and reopen — the config is only re-read at startup (closing the window is not enough).

Claude Code

Easiest path is the CLI helper, which writes the entry into the right scope and survives future schema tweaks:

claude mcp add --transport stdio --scope user apple-health -- uvx apple-health-mcp-server serve

• --scope user registers the server for every project (writes to ~/.claude.json). Use --scope project to share via a version-controlled .mcp.json at the repo root, or --scope local (the default) for the current project only.
• The -- separator is mandatory when the server command takes its own arguments — without it Claude Code would try to parse serve as one of its own flags.

Equivalent manual entry inside the chosen JSON file:

{
  "mcpServers": {
    "apple-health": {
      "type": "stdio",
      "command": "uvx",
      "args": ["apple-health-mcp-server", "serve"],
      "env": {}
    }
  }
}

A running session does not auto-reload .mcp.json edits; restart Claude Code to pick them up. Stdio servers are not automatically reconnected after a crash either — restart the session if the server goes away mid-conversation.

Codex CLI

Codex CLI stores MCP servers in TOML, not JSON. The simplest path is the helper command, which writes into ~/.codex/config.toml:

codex mcp add apple-health -- uvx apple-health-mcp-server serve

Equivalent manual entry in ~/.codex/config.toml (override the path with CODEX_HOME= if needed):

[mcp_servers.apple-health]
command = "uvx"
args = ["apple-health-mcp-server", "serve"]

Edits to config.toml take effect on the next codex invocation — restart any running session to apply them. The CLI also exposes codex mcp list / codex mcp get <name> / codex mcp remove <name> for inspection and cleanup.

Importing your export

Before any tool returns data you have to ingest your export once. Apple gives you a directory containing export.xml, an electrocardiograms/ folder, and a workout-routes/ folder; point the importer at the directory itself:

uvx apple-health-mcp-server import /path/to/apple_health_export

The import is idempotent — re-running it with a newer export merges the new rows into the existing database via the import_id column.

Database location

By default the database lands at the XDG-resolved data directory:

• Linux / macOS: ~/.local/share/apple-health-mcp/health.duckdb
• Windows: %LOCALAPPDATA%\apple-health-mcp\health.duckdb

Override with --db /custom/path/health.duckdb on either subcommand.

Tools

17 tools are registered with FastMCP, grouped by family:

Family	Tools
Record types & data	list_record_types, query_records, get_record_statistics
Workouts	list_workouts, get_workout_details, get_workout_route
Activity summaries	get_activity_summaries
Heart rate	get_heart_rate_samples
Correlations	list_correlations, get_correlation_details
ECG	list_ecg_readings, get_ecg_data
State of mind	list_state_of_mind
Me characteristics	get_me_attributes
Metadata & ops	list_data_sources, get_import_history
Escape hatch	run_custom_query (read-only validated SQL)

Updating

uvx caches the package on first run and re-uses that cached copy on subsequent invocations, so a new release does not install itself automatically. Pick one:

• Always run the latest — pass --refresh once whenever you want to pull a newer version:

  uvx --refresh apple-health-mcp-server serve
  

• Pin a specific version — write the version directly in your Claude Desktop / Codex / Cursor config so an unrelated uvx cache eviction cannot move you off it:

  {
    "mcpServers": {
      "apple-health": {
        "command": "uvx",
        "args": ["apple-health-mcp-server==0.1.0", "serve"]
      }
    }
  }
  

See CHANGELOG.md for the per-release notes.

Troubleshooting

Every tool returns "No Apple Health data has been imported yet."

The MCP server boots even when the local DuckDB file is empty so the client still sees the full tool list, but every tool that needs data returns this guidance string until you run the importer:

apple-health-mcp-server import /path/to/apple_health_export

After the import finishes, restart the MCP server (quit and reopen Claude Desktop / Claude Code / Codex, or stop and re-run the serve process). The server keeps a read-only DuckDB snapshot for the lifetime of the process; new rows only become visible to a fresh connection.

get_import_history is the one tool that stays callable on an empty DB — it returns an empty list, which is how you confirm "no imports yet" from the client side.
